TRICHODES Herbst. 



T. bimacillatns.— Dark blue, pubescent with long, soft, erecl^yellow 

 hair; prothorax convex, rugosely punctured with an indistinct dorsal line; 

 elvtra thickly but not deeply punctured with a few faint traces of strise near 

 the suture and a bright orange round spot about the middle near the side ; an- 

 tennsB black. Length .4 inch j 10 mm. 



Califoi-Dia and Oregon. This species has become quite frequent in 

 collections within the last two years. It is quite distinct from T. or- 

 natas by the prothorax more convex, less constricted in front, less 

 narrow behind, punctured and not shining. It is in these respects 

 more allied to T. Nntalh Kirby, and may perhaps be an extreme 

 variation of this species. Until intermediate forms occur it will be 

 better to distinguish it by a separate name. 



L,EB.4.SIEl,L..4. Spin. 



Li. Jiiaculicollis.— Dark blue, clothed with erect black hairs; prothorax 

 a little longer than wide, oval, convex, finely and sparsely punctured, shining, 

 red with a large disooidal black spot reaching the tip but not the base ; elytra 

 coarsely and thickly punctured. Length .2 inch; 5 mm. 



Mariposa, California; Dr. A. Thevenet. xMore elongate than L. 

 jaiithina and quite distinct by the color of the prothorax which is 

 lunger and less punctured. The antennae are testaceous with the last 

 four joints black; the legs seem to be brown. 



IlEDOBIA Latr. 



H. granosa.— Dark brown, clothed with coarse cinereous pubescence, be- 

 coming brownish at the middle of the prothorax, which is compressed and ele- 

 vated at the middle near the base; elytra densely granul.ite-punctate with 

 scattered distant, small, smooth granules; behind the middle there is on each 

 elytron a small angulatcd spot with less dense pubescence; scutellum very 

 densely pubescent. Length .17 inch; 4 mm. 



California. The prothoracic elevation is suddenly declivous and 

 almost perpendicular behind. 



XESTOBIIJM Motsch. 

 X. alfine.— Elongate, blackish-brown, very densely and finely pnnctulate, 

 clothed with yellowish-brown short pubescence, ^which in well preserved 

 specimens is probably uniform), disc of prothorax not channelled, sides not 

 strongly flattened. Length SA inch; fi mm. 



Vancouver and California. Resembles in form X. tenselatum, but 

 quite different by the finer punctuation, the less broadly flattened 

 sides of the prothorax, and by the puboscence being much finer and 

 not arranged in tufts ; the last three joints of the antennae are only 

 one-hilf longer and wider than the 8th joint, and the 2d— 8th are 

 much more slender than in X. tesseiatuni.
