perhaps a trifle more robust. Its hind femora are rather profusely 

 and evenly granulated with black, and have all the carinas decidedly 

 nigro-serrate as in scahripes. The median carina of the pronotum is 

 moderately elevated, evenly and gently arcuate, the transverse sulci 

 quite profound but with the difterent sections more closely approxi- 

 mate than in discoideus, the hind lobe somewhat the longer and acute 

 angled behind; lateral carina? prominent and bowed outward in middle. 

 Tegmina long, slender, tapering; very closely veined on basal half, less 

 so on apical, without markings. Posternal spine rather large and long, 

 directed posteriorly but not reaching the front edge of the mesoster- 

 num, not sulcate in front as in scahrljyes. 



General color above brownish ferruginous, a little paler below; the 

 dorsal held of tegmina testaceous; occiput and fastigium of vertex also 

 with a narrow line on each side of same color. Hind wings long and 

 narrow, the disk orange red; hind margin and obliquel}" inwardly 

 directed band, along with basal half of anterior field dark fuscous, the 

 apical portion faintly clouded, the scalariform space transparent, 

 vitreous. Hind tibia" brownish with a faint lavender tint, the tarsi 

 fuscous. Antennae pale on basal half, infuscated apicall}". 



Length of body, female, 45, of prononotum, 15, of tegmina, oT, of 

 hind femora, 24, of antennae, 16 mm. 



Type.—C^t. No. 9732 U.S.N.M. 



Habitat. — Sapucay, Paraguay, a single female collected by W. T. 

 Foster in February. 



While the writer is unacquainted with T. scdbripes Stal, to which 

 this insect seems to be quite closely related, it seems to be distinct. 



TROPINOTUS REGULARIS Bruner. 



Tropinotus regularis Bruner, Ent. News, XVI, 1905, p. 214-215. 



The present collection contains 9 males and 8 females of this insect. 

 Since the female was not described when the species was named, and 

 because of the material now at hand showing some variation, the addi- 

 tional description is here presented. 



Besides being much larger and more robust than the opposite sex, 

 some specimens of' both the male and the female insects exhibit a few 

 of the color variations of T. Ixvlpes Stal, but difler from it by the 

 much shorter and more robust hind femora and in being either alto- 

 gether or largel}' brown and black. The female, like the male, has the 

 discal field of the tegmina regularly maculate with black quadrate spots 

 well toward the apex. In some specimens the dorsum of pronotum is 

 largel}^ and the tegmina above the discal row of maculations entirely 

 green, in others the lower apical half and a narrow subcostal stripe on 

 the basal half is cinereous.. Hind femora prominentl}^ provided with 

 dusky bands externally and above, the lower sulcus and inner face 

 testaceous; the hind tibiie testaceous more or less regularh^ conspersed 

 with fuscous.
