MORGAN HEBARD 5 1 



distinctly iridescent^^; costal veins strongly and briefly clubbed 

 distad; intercalated triangle small but evident. Dorsal surface 

 of male abdomen not specialized. Subgenital plate of male simple 

 or greatly specialized, symmetrical or asymmetrical; styles of 

 varied distinctive types. Femora slender. Cephalic femora with 

 ventro-cephalic margin supplied proximad with (usually four) 

 long, widely spaced spines, the more distal shortest, succeeded dis- 

 tad by a more closely set row of shorter spines, terminated by two 

 long spines, the more distal the longer; ventro-caudal margin with 

 two, widely spaced, long spines meso-distad and a single long 

 distal spine. Other ventral femoral margins supplied with long 

 spines. First three tarsal joints very elongate, each supplied dis- 

 tad with a minute pulvillus *"^ produced In an elongate acute proc- 

 ess; fourth tarsal joint subquadrate, with distal half of brief ven- 

 tral surface occupied by a similar pulvillus. Small arolia present. 

 The genus is now known to Include ten species and one geographic 

 race.

The present species divides into two races in the Ignited States. 

 The present race is widely distributed over the southeastern United 

 States, but is replaced by Iidea mini?na in southern peninsular 

 Florida and In the Florida Keys. A single exotic specimen, from 

 Banos San Vincente, Pinar del Rio, Cuba, is before us, a female 

 referable to lutea lutea. 



This insect is much the smallest of the known species of the 

 Blattellitcs found in the United States. It is ochraceous-buffy in 

 general coloration, with head usually showing a transverse band 

 of bister between the eyes and occasionally below this, one, rarely 

 two, lesser bands of the same color. The pronotum is tinely pic- 

 tured with snuff brown to bister. 



In the reduction of tegmina and wings the present species is 

 distinct from the other known forms of the genus, of which near 

 relationship is shown to the genotype, C. punctulata. From that 



^= In Cariblatta imitans Hebard, alone, the wings show no trace of iridescence. 

 *^ This condition is also found in Neoblattella.
