4. Elytra tuberculate. 

 This sub-section includes several species so like one another and 

 so inadequately described, that it becomes amatter of great difficulty 

 to make them out ; fortunately I have in my collection the original 

 of S. eclmiatus, a species described by the Rev. Mr Hope from 

 an insect sent him by W. S. Macleay, whose MS. name is affixed 

 to the specimen which 1 now redescribe. 



81. Hel^us echinatus, Hoj^e. 



Trans. Ent, Soc. Lond. Vol. V. p. 54, pi. VII. fig. 1. 



Oval, black, opaque. Head very minutely rugosely punctate, 

 ti-ansverse, depressed in front, no visible clypeal suture, clypeus a 

 little emarginate in front, labrum large. Thorax very minutely 

 and roughly striolate punctate, very minutely pubescent, slightly 

 transverse, the margins thickly raised and reflected on the borders 

 the anterior angles crossing in front of the head and terminatingin 

 a narrow rounded point, leaving a transverse opening for the head, 

 the posterior angles very much curved backwards and acute, the 

 disk moderately convex and even, with alow cari.a on the median 

 hne interrupted in the middle, and a little elevated at the base. 

 Elytra slightly broader than the thorax at the base, not ampliated 

 behind, convex, the margins corrugated and slightly reflexed, 

 broad at he shoulders and narrow at the apex ; the disk coarsel^ 

 punctured ni twelve close rows, a row of glossy tubercles on the 

 alternate interstices, three of these larger than the others, one 

 rising on each side of the scutellum and running obliquely t^ the 

 suture at about one-fourth of the length from the base, and thence 

 along the suture, and consisting until near the apex of elongate 

 nearly continuous tubercles, the third and fifth rows of tubercles 

 are larger and more distant, the second, fourth and sixth rows still 

 more distant and slightly smaller. The under surface and legs are 

 opaque and very minutely granulate, the prosternum is very 

 obsoletely carmate; the antenna are setose, the four last joints 

 broader a little than the others.
