Thin .spwie.s «lilTers front all other .speeie.s of I'assalua known to me in Homctinies having 

 a distinct lamella in front of the three ordinarily found on the antennae of Kpericit of this 

 genus. Thin lamella, however, in not fullv developed as are the additional lamellae found 

 in the genu.s I'ajrilliin. Iiut is either inueh >!enderer than tho.st> following it as well u.h only 

 aliout half their length, or is «|uite short antl inronspicuous.' The anterior margin of the 

 heatl hears a pair of small hut well developetl tubercles on either side of the median notch, 

 which is con.set|Uently nnu'h more pronounced than is ever the case in I'asiUim. The 

 cephalic t idiercles ami ridge.s clo.selv resend)le those of I'ltssahts s/tiiiitjer. The pronotum 

 re>end»le> that of /'. npiniijcr in shape, but is un|)unctured except in the scars and nuirginul 

 grooves. An oval patch a little below the middle of the mesothoracic episterna, the 

 mesosternal s«-ars, the lateral areas of the metasternum. and the lower parts of the 

 shi>ulders of the elytra (but not the ejtipleura) arc covered with hair-bearing punctures. 

 The po.sterior intermediate areas of the metasternum are coarsely punctured behind and 

 on the inner side. The elytra are strongly and uniforndy puncturetl. The middle and hind 

 tibiae beor from one to three spines which are stronger on the former than on the latter.

One specimen from Nicaragua, 32 mm. long. 



This .species is very like the last, but the triconcave margin of the head betw«-fii 1 in- 

 outer tubercles is thickened and lightly conve.x as a whole ; the frontal area and the 

 pronotiim (even in the s<-ars and anteriorly weak marginal grooves) are unpuncture<l ; 

 the mesothoracic episterna, the mesosternal .s<-ars. the metasternum and the elytra are 

 hairle.Hs, the second and third being entirely unpuncttired, and the last being punctured 

 in the lateral grooves ordy : and there are no very distinct spines on the middle and hind 

 tibiae.

The head and pronotum resendile tho,se of the pre«e<ling .species in <nitline, but the 

 central tubercle is nnidi elongated with free decundient ape.x, the frontal ridges are feebly 

 developed, the anterior margin of the head is not thickened, and the .sides of the pronotum, 

 inrluding the .scars and anteriorly enlarged marginal grooves, are strongly punctured. The
