1 82 MEMOIRS ON THE COLEOPTERA 



punctate; the apical margin of the prothorax in front of the line of 

 maximum width is not quite so transverse. 



Stictalia Csy. 



This genus appears to be distinct from Bolitochara and not 

 properly a subgenus; it differs so greatly in its very wide neck and 

 unconstricted base of the head, that there can be no doubt of a 

 considerable degree of taxonomic isolation, though forming one 

 of the Bolitochara group of genera. It is peculiar to the Pacific 

 coast fauna and the species are numerous and closely allied among 

 themselves, so that much care is necessary in identification. At 

 the same time there is a good deal of diversification, as may be 

 seen in passing from punctiventris to californica, then to collaris 

 and finally through the small forms such as brevicornis. I am 

 unable to announce any synonymy among the species as hitherto 

 published, though there are several that may prove to be rather 

 subspecies than species. The following is quite distinct from any 

 other in its very much finer sculpture throughout: 



Stictalia carlottae n. sp. Somewhat stout, moderately convex, slightly 

 shining, the micro-reticulation small, rather strong, obsolescent on the 

 strongly shining abdomen; color pale castaneous, the head piceous, the 

 elytra rather pale, infumate toward the scutellum and broadly toward 

 the outer posterior parts, except at the immediate hind angles which are 

 pale, the abdomen piceous-black throughout, the legs pale; punctures 

 fine, feeble, not dense, rather close and asperate on the elytra, fine but 

 strongly asperate and rather close throughout the abdomen; pubescence 

 rather short and coarse, pale; head but little wider than long, the eyes 

 prominent, at scarcely their own length from the base, the tempora less 

 prominent, rounding to the base, becoming parallel behind the eyes; 

 antennae short, slender and pale basally, infumate and rapidly, evenly 

 and strongly incrassate distally, the second and third joints subequal, 

 each much shorter than the first, the fourth obtrapezoidal, as long as 

 wide, the tenth nearly twice as wide as long, the last as long as the two 

 preceding, sharply ogival; prothorax nearly one-half wider than long, 

 evidently wider than the head, widest at two-fifths from the apex, where 

 the sides are rather broadly rounded, thence slightly converging and 

 straighter to the base, the angles rather sharp, obtuse, the surface with a 

 very feeble simple transverse ante-scutellar impression; elytra large, 

 about as long as wide, parallel, slightly tumid at each side of the suture 

 behind the scutellum, two-fifths wider and more than two-thirds longer 

 than the prothorax; abdomen distinctly narrower than the elytra, 

 parallel and straight at the sides, narrowing very slightly at apex, the 

 three basal impressions strong. Length 2.7 mm.; width 0.72 mm.
