AMERICAN COLEOPTERA. 125 



fifth with a small pubescent apical tubercle in the male. Legs moderately slen- 

 der, first tarsal joint subequal to the two following on all the feet. Length 

 2.5 3.2 mm. 



California (San Francisco, Santa Cruz Mountains, Contra Costa). 

 One example from Miami, in the Mariposa region, is referred to here 

 with some doubt. 



This species appears to have a limited range. It is very similar 

 to fallax, which is much more widely diffused through the State, and 

 is to be separated by its larger eyes and distinct apical ventral tuber- 

 cle in the male. 



23. I*, concurrent n. sp. — Closely similar to interruptus, from which it 

 differs in its smaller eyes ( % ), coarser s trial punctures and the shorter antennal 

 joints, the tenth being scarcely more than two and one-half times as long as wide. 

 The eyes ( % ) are separated on the front by a distance which is nearly one and 

 one-third times their vertical diameter, and distinctly more than the combined 

 lengths of the second and third antennal joints. Length 2.5-2.8 mm. 



Northern Illinois, Arkansas (Stromberg). 



24. I*. ia list v n. sp. — Differs from interruptus in the smaller eyes of the male, 

 these being separated on the front by a distance which is evidently greater (about 

 one and one-fourth times) than their vertical diameter, and which exceeds the 

 united length of the second and third antennal joints; and in the absence of a 

 distinct apical ventral tubercle in the same sex. While the above differences, 

 which are those given in the table, are the most conspicuous and reliable ones, 

 there are some others which are evident on careful comparison. The head and 

 prothorax seem relatively smaller in fallax, and I think this is not due wholly to 

 the smaller eyes; the antennae are a little more slender, and the inner margin of 

 the black area is more oblique, receding from the suture anteriorly so as to leave 

 three or even four interspaces rufous, while in interruptus the inner margin of the 

 black area is more nearly parallel with the suture, seldom leaving more than two 

 interspaces rufous in front. This narrowing of the black area anteriorly in 

 fallax results in the short oblique median dash of pale hairs forming a nearly 

 continuous line with that bordering the black area in front, while in interruptus 

 the oblique dash is nearly parallel to the anterior fascia bordering the black spot. 

 These differences are easily obscured in specimens in which the vestiture is not 

 perfectly preserved. 



The species ranges from Southern California to Oregon, both in 

 and to the west of the Sierras. Those from the first named region 

 are typical; the Oregon specimens are slightly different, but I can- 

 not find good grounds for separating them. 



25. V. vegrsindis n. sp. — Of the interruptus type but much smaller; pale 

 areas rarely well defined, the suture usually and the base and apex of the elytra 

 frequently more or less completely suffused with the darker color of the central 

 area. Eyes of male more prominent than the sides of the prothorax, but dis-
