Hrum'.r : South Amkrican 'rKiRiciDK 103 



clo\atccl aiul foliaccous with its antt'rior c(\\i,c rracliiiii; the trout margin 

 of iho disk of ihi' iiroiiotiiiii, straii:;hl and tridentato, the liind part of 

 the crest less ahriipl and serrato-creniilate. Surface of tlio pronotum 

 rather closely punctate, less rucjosc than in the species with which it has just 

 been compared. Frontal costa less prominent and the rami not so widely 

 separated between the antenna^ as described for nnicristata. Lower 

 ]iosterior angles of the pronotum less prominent than in the preceding 

 species, the anterior angle jiroduccd into a blunt tooth, back of this very 

 gently crenulate. Tegmina elongate oval, the apex rounded. Wings 

 complete, a trifle surpassing the apex of the pronotal process, w'hich ib 

 smooth above instead of serrato undulate as in the i:)receding species. 

 Legs much the same as in the species with which it is being compared, 

 possibly with the carina? a trifle stronger and the teeth more pronounced. 

 General color dark fuscous, with the apical half of the pronotum and hind 

 femora tinged with ferruginous, the latter especially noticeably so. 



Length of body, d^, 8.5 mm.; of pronotum, 12.5 mm.; of hind femora, 

 5.35 mm. : length to tip of wings, 14.25 mm. ; height of pronotal crest above 

 humeri, 3 mm. 



Habitat. — -The type and onl\- sjierimen of the present si^ecies comes 

 from Para, Brazil, where it was taken during the month of July by H. H. 

 Smith. The type is in the Carnegie Museum, Pittsburgh. 



The three species of the present genus may be separated as foUow's: 

 A. Median carina of the pronotum only gently compresso-elevated between the 

 humeri; apical joint of the antenntt- pallid; carina? of anterior femora scarcely 



undulate tiirgida Bolivar. 



AA. Median carina of the pronotum greatly compresso-elevated or foliaccous; 

 carinae of the anterior and middle femora undulate. 

 b. Crest of pronotum not reaching its anterior margin, not ascending abruptly 

 in front but gradually, its height about equaling the width of dorsum 



between the base of the tegmina unicrislata Hancock. 



bb. Crest of pronotum reaching its anterior margin and ascending abruptly 

 in front, its height decidedly greater than the width of the dorsum be- 

 tween the base of the tegmina hancocki sp. nov. 



Genus Crimisus Bolivar. 

 Crimisiis Boliv.vr, Ann. Soc. Ent. Belg., XXXI, 1887, 246. —Hancock, Gen- 

 era Insectorum, fasc. 48, 1906, 40. 



The two species of this genus, neither of which is represented in the 

 material at hand for study, may be separated by the annexed table. 



A. Pronotum posteriorly lengthily subulate palruus Bolivar. 



AA. Pronotum posteriorly acuminate, not produced beyond the apex of the hind 

 femora contractus Bolivar.
