are similar scattered punctures ; the legs are noticeable for their 

 slenderness, which is even greater than that of the males of Agenius, 

 although the body of the latter is proportionately broader than that 

 of Eriopeltastes ; the anterior tibiae have two very broad, curved, 

 remote teeth, and also traces of a third in the form of ar angular 

 outcurving of the margin ; the intermediate tibiae are almost straight 

 and spiny on the outer surface like the hind ones, on which, owing 

 to the scattered spines, no teeth can be any longer detected, and it 

 differs thus most markedly in that respect from Stringophorus . The 

 tarsi are more than twice as long as the tibiae, very slender, glabrous, 

 spiny at the joints ; the very slender claws are only slightly bent, 

 and the " after claw " between them is unusually small and emits two 

 bristles ; the mesosternum is scooped out between the middle coxae, 

 and does not project. On account of the short, not convex, strongly 

 retracted abdomen, I take the only example I have obtained to be 

 a male ; I suppose that in the female the upper tooth of the anterior 

 tibiae will be more distinct, the tarsi shorter, and the antennal club 

 smaller. 



Eriopeltastes leucoprymnus. 



Black, with a flavous pubescence ; antennae, palpi, anterior tibiae 

 and tarsi, median tarsi and elytra yellowish fulvous ; anal opercule 

 (pygidium) greyish white. Length 3f mm." 



I have not yet met with this species. 



Tribe VALGINI. 



The only valid character I find to separate the insects included in 

 this Tribe from the Trichiini is the shape of the scutellum, which is 

 sharply triangular, and moderately long or very elongate. The great 

 distance separating the intermediate and posterior coxae was deemed 

 at one time to be the distinctive mark of the genus Valgus, contain- 

 ing many widely dispersed species. It has been now split into many 

 genera — too many, I think — but as in some of them that great 

 separation between the coxae is greatly reduced, it does no longer 

 remain a fundamental character. This induces me to include in the 

 Tribe the somewhat aberrant genus Calomctopus, which seems to 

 form a link between the Trichiini and the Valgini. It cannot 

 remain in the former on account of its sharply triangular scutellum ; 

 it differs greatly in general facies from the true Valgini, but it is also 

 clothed, although partly, with squamulose hairs. 



In the true Valgini the clypeus is very elongated but not cleft,
