SUBFAMILY II. — COREIN^E. 219 



Tribe II. ANISOSCELINI Amyot & Serville, 1843, 217. 



Species of medium size and elongate depressed form having 

 the head elongate, convex, much prolonged in front of the 

 insertion of antennae; tylus longer than cheeks and deflexed in 

 front of them, not compressed and elevated above them as in 

 the preceding tribe ; antennae rather slender, surpassing the 

 pronotum; beak reaching or surpassing hind coxae; pronotum 

 subhexagonal, its front portion strongly declivent, humeri 

 prominent, acutely to obtusely angled; hind femora straight, 

 stouter than the others, but not greatly swollen ; hind tibiae 

 widely dilated, usually on both sides. 



The tribe, as above characterized, comprises 11 genera, 8 of 

 which are confined to Central and South America, representa- 

 tives of the other three occurring in the United States, two of 

 them in our territory.

I. Chondrocera. 



act. Antennal segments not dilated, the basal joint usually equal to or 



slightly longer than the head. II. Leptoglossus. 40 



I. Chondrocera Laporte, 1832, 44. 



Elongate subdepressed species having the head porrect, 

 longer than wfde ; cheeks wider than tylus, convex, their tips 

 rounded; ocelli small, separated by a distance equal to that 

 between them and eyes ; pronotum with front portion strongly 

 declivent, the sides straight and converging from the acute 

 hind angles to apex, hind lobe also declivent, separated from 

 front one by an obtuse carina; apical margin of corium very 

 long, bisinuate ; connexivum narrowly exposed ; hind tibiae with 

 outer expansion angulate near middle, its front portion nearly 

 three times as wide as inner expansion. One neotropical 

 species occurs in Florida. 



156 (243). Chondrocera laticornis LaPorte, 1832, 45. 



Elongate subparallel. Head and pronotum brownish-yellow; scutel- 

 lum and elytra rather dark reddish-brown; membrane dark chestnut- 

 brown; under surface and legs pale dull yellow, the expansions of tibiae 

 thickly sprinkled with reddish dots. Antennae nearly as long as body, 



4n Gibson and Holdridge (1918a, 3) in their "Key to Genera of Anisoscelini" use 

 "Basal joint of antenna? equal to length of head or slightly longer" as the one char- 

 acter distinguishing Leptoglossus from the other genera. In at least two of our eastern 

 species, fulvicornis and corculus, this joint is distinctly shorter than head.
