1 78 Mr. A. Murray on Coleoptera from Old Calabar, 



nentj apices truncate, slightly rounded, and with the angles, 

 both external and sutural, rounded, the exterior angles most so. 

 Pygidium and part of penultimate segment of abdomen visible 

 from above. Underside finely punctate and pubescent. Legs 

 moderately broad ; tibiae ciliated ; four anterior tarsi dilated and 

 villose, the posterior two not so much dilated. 

 One specimen only received. 



2. Amphicrossus fuscus. 



Capite et thorace ignotis, ceteris nigro- fuscus, ovatus, subnitidus, 



punctatus, breviter pubescens, lateribus dense griseo ciliatis. 

 Long. — ? lin., lat. 1^ lin. 



Head not known. Thorax not known. In other respects 

 brownish black, ovate, more elongate than the other species, 

 very finely punctate, clothed with a very short pubescence ; the 

 margins ciliated with a fringe of long, close, griseous hairs. 

 Scutellum triangular, apex not very acute, less punctate than 

 the elytra. Elytra finely punctate, sides not explanate, but the 

 margin briefly reflexed, and not very broadly inflexed below; 

 shoulders not prominent, almost absent ; apex truncate, external 

 angles rounded, sutural angles obtuse. Pygidium and part of 

 penultimate segment of abdomen visible from above. Underside 

 finely punctate and pubescent. Legs moderate. 



Only the posterior half of a single specimen received ; but I 

 have thought it worth while to describe it as probably sufficient 

 to enable it to be recognized in future when an entire specimen 

 may be found. 



In addition to the above two, there are three species of 

 Amphicrosstis known, which have been described by Erichson : — 



One from North America {ciliatus). 



One from South America [lateralis) . 



One from the Indo-Malayan district {discolor). 



Mr. Wallace also brought at least one other species from the 

 New Guinea Islands. 



Ipidse. 



Cryptarcha, Shuck. 



Subgenus Arhina (from a and piv, noseless). 



At first sight I took this for a convex Prometopia : looking 

 more carefully, its resemblance to Camptodes led me to suppose 

 it an African representative form of the South-American genus 

 Camptodes (a thing not hitherto met with) ; but on examining 

 the mouth, I found that it was nothing but a Cryptarcha, As 

 the facies, however, is aberrant, and difi'ers from the usual charac- 

 ter of the genus in being glabrous and brilliantly shining, as well
