332 MEMOIRS ON THE COLEOPTERA 



inadequately described types of Gory and Percheron; large and 

 carefully collected series will be necessary before coming to any 

 useful conclusion regarding the species, which are doubtless rather 

 numerous. I believe, however, that the synonymy here suggested 

 will prove to be very near the truth. 



Devulsa Horn, is probably not closely allied to dimidiata and pos- 

 sibly may not belong to this group at all, but not having seen the 

 species I am unable to do more than give the characters assigned 

 it by its author. 



Group VIII. 

 Subgenus Parisorhipis nov. 



The single species forming the type of this group is, so far as I 

 can discover, absolutely isolated and without even an approach to 

 a close relative in the entire genus. The principal elements of 

 distinction are stated in the foregoing table of groups. The clypeus 

 is in general rather flat, the apex but little narrowed, with an angular 

 sinus extending from side to side, the obtuse subdentiform lobe at 

 each side gradually and moderately reflexed; on the vertex there 

 are two large, elongate, densely punctate and conspicuously pubes- 

 cent impressions, narrowly separated by a cariniform longitudinal 

 line. The anterior tibiae have two very long slender spiniform 

 teeth at and near the apex and, just above them, the edge is broadly 

 and feebly angulate but without trace of anything that could be 

 called even a vestigial tooth. The mesosternum is in the form of a 

 vertical polished glabrous plate, the exposed edge of which is 

 separated from the metasternum by a deep, transversely eroded, 

 punctate and very pubescent line. The tarsi are long and slender ; 

 only two joints of the posterior remain in the type, but these 

 combined are more than half as long as the tibiae. The type may 

 be described as follows : 



Form rather elongate-oval, moderately convex, very shining and black 

 throughout, the pronotum with vague trace of metallic lustre; 

 pubescence above very long, erect, evenly sparse throughout, a little 

 closer on the pronotum and yellowish-cinereous, rather longer, very 

 coarse, dense and conspicuous on parts of the sterna and femora, 

 shorter and very sparse on the abdomen; head densely but not very 

 coarsely punctate, a transversely sinuate line, bordering the impres- 

 sions of the vertex posteriorly, subimpunctate and shining; antennal 

 club black, not as long as the stem; prothorax a third wider than
