374 MEMOIRS ON THE COLEOPTERA 



from the description, in the absence of what could be termed "long 

 poils blond" and in the somewhat longer antennje, which are not 

 sharply bipartite in color as described by Chevrolat; the subbasal 

 discal fascia does not unite at the margin with the third, and, finally, 

 I cannot place the "point sutural jaune de chaque cote, plus 

 rapproche de la deuxieme que de la troisieme bande." The solid 

 apical yellow spot in nimbata is sometimes resolved into two narrow 

 fascise. Dimidiaticornis is described from Oaxaca and is a slightly 

 larger species than nimbata. 



Paraclytus n. gen. 



The species described by LeConte under the name Clytus lanifer 

 (Sm. Misc. Coll., 264, 1873, p. 198) is isolated in all its features of 

 structure and ornamentation, and cannot be closely associated with 

 either of the two preceding genera, differing in the directions noted 

 in the table given above. It is a local development, confined so 

 far as known to California and the adjacent parts of Arizona. 

 There seem to be three species as follows: 



Antennse (cf ) slightly more than half as long as the body, black, flavo- 

 pubescent; prothorax and base and suture of the elytra clothed with 

 long hairs, the former slightly longer than wide, the base constricted, 

 the sides subangularly rounded, sinuate posteriorly, densely and 

 coarsely punctate, with a short dorsal line smooth; elytra with the 

 suture, subbasal fascia, another transverse at the middle and a third 

 oblique and ante-apical, flavate; scutellum densely navo-pubescent; 

 tibise and tarsi ferruginous. Length 14.0 mm. California (Owen's 

 Valley) lanifer Lee. 



Antennae (cf) two-thirds to nearly four-fifths as long as the body; pro- 

 thorax seminude toward base, the smooth ragged dorsal line only 

 present basally ; size smaller though varying greatly 2 



2 Rather stout and convex, shining, black, the elytral suture, largely 

 expanded basally and ante-apically and not attaining the apex, and 

 an entire transverse slightly ante-median fascia, sometimes inter- 

 rupted on each elytron, pale testaceous, the ante-basal parts of the 

 prothorax and the sutural pale regions densely clothed with long 

 flavate hairs, the transverse fascia nude; head more sparsely clothed 

 with rather long pale hairs; antennae (of) infuscate, black basally, 

 not very slender, slightly thickened basally, gradually tapering dis- 

 tally, fully three-fourths as long as the body, the third joint longer 

 than the first and one-half longer than the fourth, the basal joint 

 notably stout, or ( 9 ) rather more than half as long as the body, 

 not tapering but flattened and more serrate distally, the joints sim- 

 ilarly proportioned basally, except that the third is barely as long as 

 the first; prothorax not quite as long as wide, truncate at apex and
