equal, seventh about twice the size of the sixth. Cluh rather 

 long, widest near the end, indistinctly jointed, its basal 

 portion hardly as broad as the seventh joint. Et/es nearly 

 round, placed close to the thorax. Head short, narrow above, 

 globose below. Thorax bisinuate and sliarply limited at the 

 base, without ocular lobes, usually oviform. Scutellwa 

 absent. Elytra of the same width as the thorax at the base, 

 shoulders not porrect, with a sharp slender basal margin. 

 Tarsi short, finely setose underneath ; thsir third joint entire 

 below, not broadly excavate above, rather narrow. 



Prosternum moderately long, slightly incurved at apex. 

 Anterior coxce prominent and contiguous, placed just behind 

 the middle of the prosternum. Metasternum short; hind 

 coxa3 widely distant. Abdomen long, its first segment 

 evidently shorter than the second, the intervening suture very 

 oblique towards the sides. 



The form, the position of the eyes, the rostrum, antennal 

 insertion, the gradual slope of the posterior declivity, and 

 other characters prove that this genus is not very close to 

 Phrynixus or its immediate allies. Ghanuepsephis may be 

 separated by its large broad head, which is not globose 

 below, by its more prominent and widely separated middle 

 cox£e, and by the position of the eyes ; these are distant from 

 the thorax and from each other, but in Arceoscapus they are 

 more approximated. 



In addition to the species described below this genus will 

 include Nos. 2552, 2553, and 2554, which were placed 

 temporarily in Chamcepsephis until more specimens could be 

 found. 



Arceoscapus ovipennis, sp. n. 



Elongate, subovate, slightly convex ; fuscous, thorax a 

 little rutescent, rostrum, antenna?, and tarsi red, femora obscure 

 testaceous ; sparingly clothed with minute yellowish scales 

 and patches of short, erect, coarse, pale setse. 



Rostrum rather longer than the thorax, finely punctured in 

 front, indistinctly carinate behind ; it is subparallel, but 

 minutely swollen where the antennse are inserted. Clah 

 densely and finely pubescent. Thorax slightly longer than 

 broad, oviform, but little wider before the middle than it is 

 elsewhere ; its punctuation rather shallow, somewhat rugose, 

 indistinct in front; there is a longitudinal but not deep 

 depression at the middle of the base. Elytra oval, not broad, 

 considerably narrowed behind, their posterior portion forms a 

 gradual slope ; the sutural region is a little depressed near 

 the base, there are two series of moderately large but not deep
