AMERICAN COLEOPTERA. 197 



outer edge squarely sinuate-truncate, the inner side strongly rounded ; 

 middle coxa? subcontiguous. The prothorax is also more narrowly 

 margined and the elytra more lightly striate ; the tarsi relatively a 

 little longer, the basal joint of the middle and hind tarsi a little 

 longer than the three following, barely as long as the three follow- 

 ing in Vrilletta. A single California species is known ; it has quite 

 the appearance of a large Xyletimis harrisii. 



1. E. xyletinoides u. sp.— Cylindrical, convex, two and one-half times 

 as long as wide ; brown, surface feebly shining, clothed with fine short and rather 

 sparse appressed fulvo-cinereous pubescence. Eyes not large, moderately con- 

 vex, front wide, not at all carinate at middle, punctuation rather sparse and fine. 

 Antennae (fig. 16) nearly one-third the length of the body, first joint moderately 

 short, elongate-ovai, and a little arcuate; second short, obconic ; third to eighth 

 gradually shorter and wider, the third about twice as long as wide, the eighth 

 slightly wider than long; uiuth subequal to the four preceding and but little 

 wider than the eighth, sides subparallel and a little sinuate; tenth similar to the 

 ninth but slightly narrower ; eleventh still narrower and a trifle longer, apex 

 pointed. Prothorax transverse, rather strongly and evenly convex, sides moder- 

 ately convergent anteriorly, margin narrowly explanate in front, becoming wider 

 at the hind angles, which are rounded and undefined, front angles right ; surface 

 finely punctulate and with more distant larger punctures, which are, however, 

 not coarse and show a tendency to become rugose. Elytra equal in width to the 

 thorax, surface finely rather densely punctulate, lightly striate, the strife finely 

 punctate. Under surface finely and closely punctate and finely pubescent. 

 Length 5.4-6 mm. 



California. 



Three examples have been seen, one takeu by Mr. Hopping at 

 Kaweah, the other two by Dr. Fenyes in the Sierra Madre Mount- 

 ains near Pasadena. There are no obvious antennal differences in 

 the three specimens and it is probable that they are all males. 



XYLETOMERUS new genus. 



This genus is erected for a small California species which has the 

 form, size and general appearance (except in color) of Sitodrepa 

 panicea. Structurally it is most closely related to EuvrilleUa, from 

 which it differs in antennal and palpal formation as follows: The 

 terminal joints of both maxillary and labial palpi are narrower, 

 fully twice as long as wide, feebly dilated apically, with the outer 

 edge strongly oblique. The antennal club is obviously longer than 

 all the preceding joints, the joints of different form ; the funicular 

 joints not more than half as wide as the club, scarcely serrate.
