Cariblatta minima Hebard 1916

Cariblatta lutea minima Hebard (Plate II, figures 3 to 5.) 1916. Cariblatta lutea minima Hebard, Trans. Am. Ent. Soc xlii, p. 170, pi. XIII, fig. 4. [cf, 9 ; localities listed in present paper.]
This geographic race is confined to southern peninsular Florida and the Florida Keys. It may be separated from t^'pical Iiitea by the average smaller size; average paler and more yellowish buff, rather than distinctly cinnamon, tones of general coloration; more decided tegminal reduction, particularly in the male sex, in which these organs show fully as much reduction as in the female; apparently always vestigial wings, and by the narrower median production of the male subgenital plate.
Type. — cf ; ?^Iiami, Florida. March 3, 1915. (M. Hebard.) [Hebard Collection, Type no. 418.]
Description of Male. — Type. Size very small, form slighth' more robust than is normal in typical lutea. Pronotum with point of greatest width at the latero-caudal angles, caudal margin nearly straight, more truncate than in this sex of lutea. '''^ Tegmina decidedly reduced, reaching only to base of seventh dorsal abdominal segment; with three longitudinal discoidal sectors (thus the median vein branches but once) and no cross-veinlets. Wings vestigial. Supra-anal plate as in typical lutea. Subgenital plate as in that race, but with specialized styles slightly closer to each other and production of intervening portion of distal margin very small, subquadrate, very slightly longer than wide.
Allotype. — 9 ; Miami, Florida. March 14, 1916. (M. Hebard.) [Hebard Collection.]
Description of Female. — Allotype. Similar to male, but larger and distinctly more robust. Pronotum slightly broader, caudal margin straight, truncate. Tegmina and wings much as in male, except that dextral tegmen has four discoidal sectors. Supra-anal plate very small, strongly transverse, weakly produced, with distal margin showing a small, short, median concavity. Subgenital plate as in tpical lutea.

" As we have found elsewhere in the Blattidae, tegminal reduction appears to be accompanied by a broadening of the pronotum, with a lessening of the convexity of the caudal margin and a coincident shifting caudad of the point of greatest pronotal width. The pronotal features given above show rather this adjustment than what might appear, to the casual observer, to be features separating the present race from lutea lutea and the species widely from the other members of the genus. The flattening of the caudal margin of the pronotum is more pronounced in this race, which shows normally greater tegminal and wing reduction than does typical lutea.
The young of this race are inseparable from those of hitea lutea. The habits of the insect agree fully with those of the more northern race; but, when present, we have found lutea minima decidedly the more numerous.
The single ootheca before us is 1.8 mm. in depth. The dorsal and ventral margins are parallel and very slightly cur'ed, the dorsal (suture) being supplied with widely spaced, minute knobs"'-; the divisions of the Qgg sacks are distinctly indicated on the weakly roughened, moderately convex sides, by widely spaced vertical ines. The single example before us bearing an ootheca, is carrying this egg case with suture laterad.''^
