Distribution.- — Alabama: Mobile cand vicinity, May and June (Loding);

This species is quite easil}^ recognized by its stout suboval 

 form, pale color and subregular striae. There is considerable 

 variation in several respects; the ocular lines are usually ap- 

 parently absent, but occasionally are detectable a little removed 

 from the eyes. The sexes differ less than usual in cephalic 

 characters, the eyes in some males being fully as distant as in 

 some females, and the terminal joint of the maxillary palpi is usu- 

 ally — or at least often — nearly as pointed as in the female. 



27. Pachybrachys placidus new species 



Dull yellow, prothorax reddish yellow, head reddish brown, 

 lustre dull, upper surface without spots, venter dusky except 

 the margins; ocular lines wanting. Ave. length 3 mm. Ari- 

 zona. 



Head thickly punctate, uniformly dark reddish brown. Eyes lai'ge but 

 scarcely prominent, separated in the female by a distance equal to the length 

 of the first two antennal joints, and much less than the vertical width of their 

 upper lobes. Antennae short, not ciuite half as long as the body ( 9 ), joints 

 nine and ten twice as long as wide, outer joints dusky. 



Prothorax moderately transverse, widest at about basal fourth, sides a little 

 retracted and slightly sinuate before the basal angles, moderately convergent 

 and broadly arcuate toward the front, closely punctate almost to side margins, 

 the latter very narrowly smooth. 



Elytra parallel, about twice as long as the prothorax, quite regularly striate 

 in posterior half, the punctures more or less confused anteriorly, more especially 

 in a narrow baso-sutural triangle; striae everywhere finely impressed, a little 

 more noticeably at sides, the punctures fine and scarcely at all brownish; sub- 

 marginal stria nearly regular, the mai'ginal interspace punctured subserially 

 in basal half; shield small but distinct. 



Legs pale throughout; front claws (9) barely appreciably larger than the 

 others. 



Length 2.75 to 3.15 mm.; width 1.4 to 1.7 mm. 



Distribution. — Arizona: Huachuca Mts., July 14-20 (Wenzcl). 



Only two examples of this species — both females — have l)een 

 submitted to me. It is easih' recognizable among the yellow 

 species by the narrowly separated eyes and absence of ocular
