fahraei Fst.), Hip. alternans Fahr., Tan. ellijMcus Pasc, Hip. 

 hertince Fst., and possibly some other species among the Tanyr- 

 rhynchi described by Boheman in which the femora are unarmed. 



Origenes, gen. nov. 



Head deeply set in prothorax, continuous with rostrum, ante- 

 ocular fuiTOws absent ; eyes elongate, transverse and subdepressed, 

 with their uj)per edge strongly elevated above tlie level of fore- 

 head. Rostrum as long as head and prothorax, curved and 

 strongly dilated apically ; scrobes deep and continued to beneath 

 base of rostrum. Antennce inserted near apex of rostrum ; scape 

 not reaching eye ; funicle with seven joints, 1 and 2 longer than 

 the others and of equal length, 3-7 short and subequal ; club 

 large, elongato-ovate. Prothorax transverse, sides rounded, base 

 truncate, apex truncate dorsally and with very large ocular lobes 

 upper surface tuberculate and with a broad central furrow. 

 Elytra very short, ovate, apices jointly rounded in both sexes, 

 shoulders roundedly prominent ; upper surface convex, foveolato- 

 sulcate, the intervals tuberculate. Abdomen with segment 2 

 about as long as 3 and 4 togethei- and separated from 1 by a 

 distinct curved suture ; intei-coxal piece broadly truncate. Legs 

 rather short, femora slightly clavate, tibiae simple, corbels of 

 posterior pair broad and open ; tarsi short, spongy beneath, joints 

 of about the same width, 2nd and 3rd subequal, 1st longer ; 

 onychium rather elongate ; claws free. 



This genus, which was proposed by Mr. Peringuey, contains 

 only one described species, viz. Hipporrhinus callidus Gyl. ; but 

 there are two or three undescribed species of similar facies which 

 Avill probably have to be included in it.
