middle and obsoletely in the middle before the base; punctures fine, feeble 

 and sparse. Elytra one-fourth longer than wide, the sides subparallel and 

 nearly straight ; apex transverse ; humeri not exposed ; disk scarcely visibly 

 wider than the pronotum but nearly two and one-half times as long, coarsely 

 strongly confusedly and not very densely punctate. Abdomen with nearly 

 four exposed segments, shining, subimpunctate and not distinctly pubescent. 

 Length 1.7-1.9 mm. ; width 0.7-0.8 mm. 



California (Sta. Cruz Co.). 



The two specimens are males, having the median elevated plate 

 of the terminal ventral segment large, trapezoidal in form, twice 

 as wide as long with the apex transversely truncate ; anterior tibiae 

 simple. In the female the pronotum will probably prove to be 

 distinctly shorter, as in californicum, tibiale and diversicolle. 



A. piinctatum. — Rather broad and cuneiform, pale rufo-testaceous, 

 the elytra more flavate, the abdomen sometimes feebly clouded with darker ; 

 integuments glabrous and very highly polished, the pronotum without trace 

 of reticulation or alutaceous lustre. Head four-fifths as wide as the protho- 

 rax, the eyes very prominent ; surface obsoletely, longitudinally biimpressed, 

 rather coarsely sparsely and unevenly punctate ; ocelli large and separated 

 by fully one-third of the width ; antennae as long as the head and prothorax, 

 outer six joints gradually thicker, tenth one-third wider than long and twice 

 as wide as the third. Prothorax three-fourths wider than long; sides sub- 

 parallel, feebly arcuate, a little more convergent anteriorly ; base distinctly 

 wider than the apex ; disk highly polished, very coarsely deeply and some- 

 what closely punctate, feebly impressed near the sides behind the middle and 

 obsoletely and unevenly along the median line. Elytra about as long as wide, 

 at the obliquely rounded and scarcely exposed humeri barely wider than the 

 prothorax but one-half wider near the apex, two and one-half times as long ; 

 sides divergent and nearly straight ; apex broadly, evenly rounded through- 

 out the width ; disk broadly impressed along the suture; punctures coarse, 

 deep, confused and rather close. Abdomen with three or four exposed segments, 

 shining, flat, scarcely perceptibly and remotely punctulate. Length 2.0-2.5 

 mm.; width 1.1-1.2 mm. 



California (Sta. Cruz Co.). 



This Rpecies is allied in general form and more distant ocelli to 

 pothos, but differs much in its more convex and polished, less trans- 

 verse and very coarsely punctate pronotum. It is represented by 

 four females. 



A. ti1>iale« — Subparallel, rather convex, shining, subglabrous, pale rufo- 

 testaceous, the antennae dusky toward tip ; elytra more flavate, the abdomen 

 piceous-black ; head and pronotum alutaceous. Head three-fourths as wide 

 as the prothorax ; eyes moderately prominent; ocelli distant by one-third the 

 width ; surface perfectly flat and unimpressed, minutely, rather closely punc-
