One specimen. Differs from the two other species of the genus 

 in the relatively broader pi-othorax and elytra, the prothorax more 

 rounded at the sides and with an additional fovea at the base, the 

 fifth ventral segment shorter, the elytra black at the apex and also 

 infuscate at the base. In the absence of the male, the species can 

 remain under Laccoderus for the present. 



EuRYPiNUS, n. gen. 



Head short, obliqiiely narrowed behind the eyes, with distinct frontal 

 groove, the epistoma not longer than the labrum, the antennae inserted beneath 

 the feebly raised orbits, short ; eyes large, rounded, entire ; terminal joint of 

 the maxillary palpi narrow, oval, obliquely truncate at apex ; prothorax trans- 

 versely quadi'ate, without lateral carina, conspicuously bifoveate at the base, 

 and excavate down the middle ; scutellum transverse ; elytra long, confusedly 

 punctate ; anterior coxae conical, exserted, the cavities open behind ; intermediate 

 coxae narrowly separated, the cavities closed externally by the sterna ; legs 

 rather short ; tibiae with minute spurs ; tarsi narrow, the penultimate joint 

 lobed and broader than the preceding joint, the claws appendiculate ; ventral 

 segments 4 and 5 equal in length, 2 with a pubescent pad in ^ . 



Type : E. mjasae. 



The single species from Tropical Africa from which the above 

 characters have been taken is very nearly related to the S. American 

 forms here included under Laccoderus, and the peculiar ^ ventral 

 pad (like that of Mycterus cMrcuUonoides) is similar ; but as the 

 African insect has a smaller and narrower apical joint to the maxilla I'y 

 palpi, and the two large dorsal foveae of the prothorax replaced by a 

 broad median channel, it is best placed in a separate genus. The 

 elytra have each a conspicuovis elongate callosity near the suture before 

 the apex, a character present or perceptibly traceable in various allied 

 forms. The much larger eyes and mesially sulcate prothorax separate 

 Earypinus from Lacconotus. 



1. — Eui-ypinus nyasae, n. sp. 



Elongate, depressed, sub-parallel ( <? ), much widened posteriorly ( ? ), 

 moderately shining ; ferruginous, the eyes, antennae, palpi, elytral callosities, 

 and abdomen, and the legs in part, piceous or infuscate ; densely, finely, 

 confusedly punctate, and somewhat thickly pubescent. Head slightly depressed 

 in the middle between the eyes, the latter more prominent in g than in $ , and 

 separated by a little less than their own width ; antennae about reaching the 

 base of the prothorax, rather stout, joint 3 longer than 2 or 4, 6-10 transverse, 

 11 ovate. Prothorax strongly transverse, in ^ narrower than, in 9 as broad 

 as, the head together with the eyes, sub-truncate at the base, the anterior angles
