382 Dr. G. A. K. Marshall on new 



bearing ten complete striae, with the lateral margin excised 

 for the reception of the base of the metepisternum, and the 

 apices separately rounded, leaving the pygidiuni slightly 

 exposed. Wings functional. Legs rather short ; the front 

 coxie contiguous and in the middle of the prosternum, the 

 hind pair not reaching the elytra ; the trochanters without 

 any bristle ; the femora moderately clavate, unarmed ; the 

 tibiae cylindrical, without any apical mucro, the corbels of 

 the posterior pairs almost transversely truncate ; the tarsal 

 claws rather small, free, and simple. Sternum with the 

 centro-sternal piece of the prosternum forming a small 

 separate tubercle ; the outer and. posterior sides of the 

 mesepimeron forming a very wide obtuse angle : the meta- 

 sternum at its shortest as long as a mid-coxa, with a deep 

 antecoxal impression, the base of the episternum only two- 

 fifths the length of its side. Venter with the intercoxal 

 process ogival and much narrower than the coxa ; ventrite 1 

 separated from 2 by a deep sinuate incision ; 2 as long as 

 3 + 4; 5 about as long as 3, gently sinuate at the apex in 

 the c? only ; 6 (withdrawn) entirely chitinised in the ? , the 

 unusually short forked strut being fused with its basal 

 margin (text-fig. 3, b) ; in the <$ 6 is also chitinous except 

 along a median membranous strip (text-fig. 2, b) ; in the <$ 

 all the exposed ventrites bear a continuous longitudinal 

 median impression. 



Genotype, Frontodes brevicornis, sp. n. 



The only known species looks like a small Cepurus, Schh., 

 but in the latter genus the prothorax is much larger in pro- 

 portion to the elytra ; the eyes are elongate, transverse, not 

 prominent, and approximated above ; the apex of the epi- 

 stome is not asymmetrical ; the scape barely reaches the 

 eye, and the funicle has seven joints, etc. 



The only other genus in the subfamily that has only six 

 joints in the funicle is the European Limobius, Schh., but it 

 differs, inter alia, in its long rostrum, elongate depressed 

 eyes, narrow forehead, etc. 



It may be noted that the asymmetry of the margin of the 

 epistome occurs also in Hypera. 



Frontodes brevicornis, sp. n. (PI. XIII. fig. 1.) 



Colour piceous, with moderately dense grey-brown scaling 

 (not entirely concealing the integument), each elytron with 

 a very ill-defined grey transverse patch behind the middle. 



Head with the forehead and the disk of the vertex
