MISCELLANEOUS NOTES AND NEW SPECIES 359 



genae bright blue-green; frontal tumidity with moderate erect hairs; 

 labrum much produced and sharply tridentate medially; antennse mod- 

 erate, the third and fourth joints bright coppery red, each banded with 

 blue near the apex; prothorax short, obtrapezoidal, rugulose, nearly 

 twice as wide as long, subequal in width to the head, the apex and base 

 brilliant blue, the tranverse region between the sulci bright cupreous; 

 elytra one-half longer than wide, three-fourths wider than the prothorax, 

 inflated posteriorly and much wider at about posterior third than at 

 base, dull sericeous-green, the lateral margin very broadly shining blue, 

 this border angulate within at basal fourth and at the middle, abruptly 

 narrowed and obsolete apically; finely reflexed lateral margin brilliant 

 cupreous; surface finely, rather obscurely punctate, closely granulate, the 

 granules shining and mingled with others that are smaller, without trace of 

 subsutural impression; the only pale marking is a feebly oblique discal 

 median band, from the broad blue margin to inner fourth, and an externally 

 attenuated apical spot; under surface brilliant green, the sides of all the 

 sterna bright cupreous; legs shining cupreous, the knees redder. Length 

 ( 9 ) 14.0 mm. : width 5.8 mm. California (Dutch Flat, Placer Co.). G. 

 R. Pilate. 



This form may be placed near lauta Csy., and is rather closely 

 related; it seems, however, to be specifically valid. 



BOSTRYCHID^: 



In the male of Apatides Csy., the apical part of the elytra is apt 

 to be smoother and more punctureless than in the female, especially 

 toward the suture ; in the following species this feature is carried to 

 an extreme: 



Apatides pollens n. sp. Stout, cylindrical, deep black and shining; 

 head well developed, the neck longitudinally plicatulate, the vertex 

 moderately convex, finely and sparsely punctate; eyes convex and 

 prominent; antennae of the usual structure in the genus, blackish, with 

 rufous club; prothorax subquadrate, convex, a little wider than long, the 

 parallel sides slightly arcuate; apical processes approximate, slender, 

 abruptly turned upward at the apex, separated by between a fourth and 

 fifth of the entire width; surface coarsely granose, with a few reflexed 

 acute teeth at the sides anteriorly; near the base, toward the sides, the 

 surface becomes smooth, polished and minutely, sparsely punctulate; 

 elytra barely wider than the prothorax, more than three-fourths longer 

 than wide, the sides straight, the apex rapidly rounded; surface strongly 

 declivous at apex, with evenly elevated sutural margin, smooth and highly 

 polished and almost completely impunctate in about apical third, coarsely 

 but not very closely punctate in basal two-thirds, finely toward the sides, 

 the suture elevated basally, the humeri rather prominent; legs weak, 

 short and rather slender, deep black; abdomen finely and densely punctate 

 throughout, the punctures bearing small erect hairs. Length (cf) 16.0 

 mm.; width 5.8 mm. Arizona (Bill Williams Fork), F. H. Snow.
