apex of front femora with tAvo long spines on lower margin. Other 

 characters as given in generic key. One species, many times re- 

 corded from the Southern United States as Cerutitioptcra dia- 

 pJicina (Fab.), occurs in our territory. 



13. AGLAOPTERYX GEMMA Hebard, 1917a, 32. Little Gem Cockroach. 



Head clay-yellow with a broad, dark brown band on under side between 

 the eyes, this sometimes continued downward on the face; pronotum 

 transparent buffy, its disc bordered in front and each side with a narrow 

 blackish-brown stripe, this broadening toward base, disc also with an an- 

 chor-shaped cross-bar of dark brown; tegmina buffy with the black length 

 wise stripe of pronotum extending obliquely back along the anal field to 

 suture and continuing along it to tips; dorsal surface of abdomen black- 

 ish-brown marked with dull orange; legs and under surface buffy, the 

 abdomen margined with blackish-brown. Pronotum with front margin 

 transverse, side margins broadly convex, hind margin feebly bisinuate, 

 front and hind angles broadly rounded. Tegmina subquadrate, a little 

 longer than wide, extending only slightly beyond first dorsal segment ol 

 abdomen; their tips broadly rounded. Ootheca 2.8x4.8 mm.; the suture 

 with a row of 18 blunt teeth. Length of body 17 , $, 7.58.9, 9, 8.69.7; 

 of pronotum, $, 2.7 3, 9, 2.9 3.2; of tegmina, $ and 9, 3.5 4.1 mm. 

 Width of pronotum, $, 3.84, 9, 3.94.3; of tegmina, $ and 9, 2.53 

 mm. (Fig. 33, A.) 



1T The measurements following the descriptions of Blattida? in this work are the ex- 

 tremes of the two sexes as given by Hebard (19173). He, having had many more examples 

 before him than are available to me, was able to <=how much better the variability in 

 size of each species. The length of body is considered as the length from the vertex 

 to the end of the subgenital plate of the dried insect.
