Narrowly oval, subconvex. Black, shining; cheeks each with a small 

 median red spot, sometimes wholly reddish-yellow; pronotum with two 

 spots near front margin, three in a transverse row near middle, and 

 often the tips of humeral angles, red or orange-red ; scutellum with a spot 

 on each basal angle and another covering the apex, red or yellow; costal

 spine of second ventral and spot on outer margins of ventrals 2 and 5 

 reddish. Antennae black, joint 1 scarcely reaching tip of tylus, 2 more 

 slender, three and a half times as long as 1, 3 and 4 subequal, each 

 slightly shorter than 2, 5 tapering, slightly longer than 4. Head de- 

 pressed, sparsely irregularly punctate, cheeks concave. Pronotum 

 broadest across humeral angles, narrowed behind them, sides sinuate; 

 disk, as well as that of scutellum, sparsely and unevenly punctate. 

 Front tibiae of male with apical half flattened, its outer margin much 

 expanded. Length, 11.5 — 13 mm. 



Florida (VanD.). Bogota, Columbia (British Mas. Coll.). A 

 neotropical species of wide distribution and exceedingly vari- 

 able color. The typical form above described is known in this 

 country only from Florida. 



VI. Perillus Stal, 1862, 88. 



Small or medium sized oval species having the head more or 

 less declivent, longer than broad, its apex broadly rounded or 

 subtruncate ; cheeks broad, equalling tylus, slightly concave, 

 their margins parallel ; beak reaching or slightly surpassing 

 middle coxae, its second joint almost as long as the next two 

 united, the third shortest ; pronotum with front portion moder- 

 ately to strongly declivent, its side margins straight, entire, 

 humeral angles obtusely rounded; scutellum relatively broad, 

 not widened behind the middle, its tip broadly rounded ; apex 

 of corium oblique, feebly sinuate ; membrane passing the tip of 

 abdomen ; connexivum narrowly or not at all exposed ; ventral 

 spine short, obtuse, scarcely reaching hind coxae ; osteolar canal 

 long, curved, its margins broad, flattened ; tibiae sulcate above. 



Six species are known, all from Mexico and the United States, 

 three of which occur in our territory. 



KEY TO EASTERN SPECIES OF PERILLUS.
