but no doubt more or less variable as indicated by the presence of a 

 greenish tinge about the head and thorax of one of the male specimens. 

 Tegmina darker brown, the mottlings more or less scattered and com- 

 posed of rather small irregular flecks instead of large blotches or well 

 defined transverse bands, though at times there is a tendency toward the 

 latter near the apex. Both females possess a pale median dorsal stripe 

 which reaches from the fastigium to the tip of the closed tegmina, while 

 in the males it is absent. Pronotum above with the usual decussate or 

 x-shaped pale lines along the lateral caring and the dark discal markings 

 common to most of the members of this and related genera ; sides with 

 a median obscure patch ({^) or scarcely so provided ( ? ). Hind femora 

 heavily marked above and internally with three dusky bands which are 

 continued on the outer disk as oblique bars ; apices of femora and ex- 

 treme base of tibiae also black ; lower edge and tibiae largely blood-red, 

 the former sometimes inclining to testaceous, base of latter broadly pale 

 on outer and inner faces, most pronounced in the female. In the male 

 the apical third of hind tibiae is strongly tinged with bluish purple. 



Length of body, <$, 26, ?, 35 ; of pronotum, J\ 5, ?, 6.75 ; of teg- 

 mina, J\ 24.5, 9 , 28 ; of hind femora, $, 17, 9, 21 millimeters. 



Habitat. Two males and two females, Sapucay, Paraguay. 



Tropinotus regularis n. sp. 



A rather small but robust insect in which the tegmina and wings ex- 

 tend but little beyond the apex of the hind femora. In color it is nearly 

 uniform wood-brown above becoming paler below. The dark markings 

 of the discal field of tegmina are quite uniform and separated by trans- 

 verse parallel dirty white bars. 



Length of body, 28 mm ; of pronotum, 9, of tegmina, 23, of hind 

 femora, 16.5 millemeters. 



Habitat. A single male specimen from Sapucay, Paraguay. 



This insect was referred to by James A. G. Rehn in his paper 

 entitled " Records of some Paraguayan Orthoptera with the 

 Description of a New Genus and New Species," (ENT. NEWS, 

 xvi, p. 38). 



The insect falls into the section of the genus where the 

 members have the pron6tal crest smooth throughout. The 

 four species of the region which belong here may be separated 

 by the annexed table : 



A. Crest of the pronotum more or less crenulate, or even serrulate, pos- 

 teriorly. Genicular angles of hind femora acute, a little 

 lengthened discoideus, rosulentus, etc. 



A.". Crest of the pronotum smooth posteriorly. Genicular angles of hind 

 femora more rounded.
