3 — Vestiture of the elytra squamiform ; inner ridge strong and continuous to the 



apical declivity bicornis Web. 



Vestiture more hair-like and still more unevenly disposed in clusters ; inner ridge 



feeble and much interrupted, the outer almost obsolete aritliger Lee. 



4 — Elytral vestiture long and hair-like, very sparse and almost evenly disposed ; 



ridges fine, feeble and subobsolete calif ornicus Horn 



5 — Antennae io-jointed as usual tr uncaticollis Lee. 



Antennse 9-jointed. Evenly cylindrical, black, the antennas and tarsi paler ; vesti- 

 ture coarsely hair-like, fulvous in color, dense and conspicuous, somewhat un- 

 even on the elytra but much less nucleated than in triincaticollis. Head 

 moderate, opaque, pubescent, the eyes well developed ; antennse as long as the 

 width of the head, the funicle 4-jointed. Prothorax nearly as long as wide, 

 roughly tuberculose, pubescent, the basal angles acutely prominent; median 

 line somewhat depressed. Elytra slightly wider than the prothorax, two and 

 one-half times as long as wide, coarsely, densely, unevenly punctured and finely 

 tuberculose. Legs rather short and slender, the hind tarsi longer than the tibise. 

 Length 6.4 mm.; width 1.8 mm. New Jersey (Woodbury). 



angustus, sp. nov. 

 In the males the elytral apices are minutely spinulose throughout, 

 but there is very little sexual difference otherwise, except that the male 

 is generally smaller and with the elytra less elongate. It will probably 

 prove necessary to generically separate the American species of Bostri- 

 chus from the European forms, when the family is monographed as a 

 whole. 



Micrapate, gen. nov. 

 This genus is founded upon the Sinoxylon dinoderoides of Horn, 

 and its allied species, and I have ventured to include also the S. simplex 

 of that author, although the size is so much greater that renewed obser- 

 vation would possibly disclose some divergencies of a generic nature. I 

 should have been disposed to refer the specimens described above under 

 the name Amphicerus brevicollis to S. simplex, were it not for the fact 

 that the basal parts of the pronotum are said to be " densely punctate," 

 which language it would be impossible to apply to brevicollis, where the 

 sculpture of that part consists of short, isolated and longitudinal raised 

 lines, as in the Amphicerus teres of Horn. It is a peculiarity of Mi- 

 crapate that the basal parts of the pronotum are truly and simply punc- 

 tate, and not in any way asperate, granose or tuberculose. Our species 

 "are as follows: — 



Pronotum less densely or rather sparsely punctured toward base ; size much smaller, 



never materially exceeding 4 mm. in length 2 



Pronotum densely punctate toward base , 3 



2 — Surface '* feebly shining;" suture moderately and evenly elevated on the apical 

 declivity. Arizona and Texas (Brownsville) dinoderoides Horn
