5. Teretilanguria ? 



Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 



A single specimen of a very narrow Teretilanguria with brownish elytra, but other- 

 wise coloured as T.panamce; it cannot be properly characterized in the absence of 

 the male. 



6. Teretilanguria ? 



Hab. Mexico, Jalapa (Hoge) ; Guatemala, Purula (Champion). 



Two specimens, one from each of the above localities, and not altogether agreeing 

 with each other, present a very puzzling aspect. They appear to be very closely allied 

 to T. nigro-wnea, but the eyes are less prominent and the cephalic structure is rather 

 that of Trapezidera. They probably belong to another genus, but the evidence is 

 insufficient for their proper assignment.

This species is only distinguished from L. sanguinicollis, Chevr., by having the 

 interstices of the punctured striae of the elytra with a very fine series of small punc- 

 tures, the punctures varying in strength. This is what I suppose to be implied by 

 Crotch's remark " distinct by the punctate interstices ;" but as he does not include 

 L. sanguinicollis in the North- American species, nor say from what it is distinct, the 

 remark is ambiguous.

The type is in Crotch's collection ; this specimen being now before me, I am able to
