'\ concealed by the ample pallium and with the sides partially hidden 

 beneath the short broad infraccrcal plates which overlie the borders of 

 the supraanal plate in this species; the median sulcus iiurrovv with 

 moderately elevated marj^-ins; furcula well developed, half as lon.r us 

 the supraanal plate and very broad, iKnirly half as broad iis loiif 

 touching- at the base and narrowed distally to a broadly rounded apex 

 the narrowing- more on the inner side; cerci very broad, about twice 

 as long as the basal width, tapering but little and that on the under 

 side of the apical third, the tip broadly rounded, thi; whole giMitiy 

 upcurved l)ut scarcely inclined inwards; subgcnital plate l)lack, the 

 tip elevated a little above the lateral margins and narrowly und shal-

Though the type of both this species and 21. cuneidu^s are in the 

 Museum collection I can lind no stable character for separating them. 

 The latter is the larger species, considering only the types, but with a 

 series, such as the one now before me, that is seen to be inadeciuatc 

 for their separation. As for the tubercled subgcnital plate of ocd- 

 dentalis^ as given l)y Scudder for the separatit)n of that species from 

 cuneafm, I nmst confess an inability to make anything out of it. The 

 cerci of cuneatus seem however to be shorter and inferiorly more 

 lobed than in occidcutaIli<. 



The males of this species, as represented by this series. \ary in 

 measurements as follows: 



Length of body, 1!) to 2o nun.; elytra, S.5 to 16 nun.; hind femora, 

 lO to 11 nun. The specimen from which the mininuim measurement 

 of the elytra was taken was collected at Glenwood Si)rings on duly 5, 

 and is an unique specimen of its kind so far as nrorded. no other 

 known individual having elytra less than 12 nun. in length.
