l^-i Mr. G. J. Arrow on Coleoptera 



from Para, from which place he examined and labelled an 

 example in the British Museum. Tiiis, the only one from 

 that locality, I regard as the real type. Other specimens in 

 Pascoe's collection were brought from E2:a, while two were 

 labelled Rio by him, probably in error. In this species the 

 prothorax lias only very slight rudiments of dorsal costte and 

 the elytra bear widely interrupted, instead of continuous, 

 carina. In that described by Dr. Sharp from Central America 

 there are strongly elevated ridges upon the prothorax, which 

 is rather longer and less wide at the front margin, and the 

 ridges upon the elytra form continuous costse. I propose to 

 call this L. ornatus, the name at first intended for it by 

 Dr. Sharp. The type is from Paso de San Juan, Mexico. 

 I cannot distinguish from this the form labelled " type " by 

 Pascoe. 



Bothrideres mitshus and merus, Pasc, both belong, in my 

 opinion, to B. viftatiis, Newm., and B lobatus, B. versutus, 

 and B. servus, Pasc.j also form a single species. The types 

 of all these are in the National Collection. 



Bothrideres simplex, incidentally mentioned in the Biol. 

 Centr.-Amer., Col. ii. pt. 1, 1895, p. 489, is not, as Dr. Sharp 

 supposed, a species described by Pascoe and must therefore be 

 called B. simplex. Sharp. It is from Rio de Janeiro. 



Pycnomerus sophorce. Sharp, is the species described long 

 previously as Lyctus depress iusculus, White *. 



The specimens from Panama (with the exception of one 

 from Tol^) , referred to Ethelema sohrina. Sharp, in the descrip- 

 tion of that form, belong in reality to another species which 

 I describe here : — 



Ethelema gracilis, sp. n. 



Nigra, omnino setosa ; elytris post medium griseo-fasciafcis, posfcice 

 fuscis ; prothorace valde convexo, marginibus lateralibus depressis, 

 vix denticulatis, angulis posticis obsoletis. 



Long. 3'o-4 mm. 



Hah. Panama : Chiriqui, Bugaba, David, Told, 

 The prothorax is very convex, with the lateral margins 

 depressed and not distinctly serrated, and the hind angles are 

 rounded off. The elytra are decorated with a band of grey 

 scales behind the middle, enclosing a dark spot on each side, 

 and the part lying behind this band is dark. 



* It may be mentioned here that Lyctus retractus, Walker, is a species 

 of Ptilinus.
