of the female is slightly less than the length of the basal joint 

 of antennae, in the male it is only about half its length. Tlie 

 legs are sometimes almost entirely flavous, but usually the 

 middle and hind ones, or the hind ones only, are infuscated; 

 the elytra are sometimes quite as black as the prothorax, but 

 are usually obscurely paler (dark brown). 



DiTROPIDUS SIMILIS, U. sp. , 



J . Black ; labrum, basal half of antennae, and parts of 

 legs pale. Glabrous. 



Head subopaque and with indistinct punctures. Eyes 

 rather widely separated. Prothorax about thrice as wide as 

 long, sides strongly rounded; punctures very small. Elytra 

 short; striae and punctures much as on vagans and tran- 

 quillus. Length (d", 9)? 1*75-2 mm. 



9 • Differs in the usual particulars of eyes, legs, and 

 abdomen.

At first sight apparently belonging to tranquillus, but 

 head subopaque and with much less distinct punctures, 

 punctures of prothorax slightly smaller, and of abdomen 

 sparser, and metasternum impunctate in middle. The lateral 

 striae of the elytra are of the usual depth, but some of the 

 ordinary rows of punctures appear to be in striae, much as 

 on vagans and tranquillus, although less conspicuously than 

 on the preceding species, from which it also differs in its more 

 widely separated eyes. On the only male in the Museum the 

 tarsi and parts of the tibiae are obscurely pale, but on four 

 females the middle and hind femora only are infuscated, the 

 rest of the legs being usually of a rather bright flavous, the 

 muzzle also is brighter than on the male; on the females the 

 median line of the head is fairly distinct, but it appears to 

 be absent from the male. 



D. Front angles of 'prothorax of male -flavous. 



DiTROPIDUS LATEROAPICALIS, n.Sp. 



S . Black; front half of head, basal half of antennae 

 (club infuscated), palpi, front angles of prothorax, pres- 

 ternum, part of mesosternum, and most of legs flavous. 

 Under-surface and legs scarcely visibly pubescent. 



Head with sparse punctures; median line well defined. 

 Eyes rather close together. Prothorax about twice as wide
