138 MEMOIRS ON THE COLEOPTERA. 



Dolosota tergina n. subsp. Similar to redundans but still more parallel, 

 the antennae infumate at tip, the head not quite so transverse, with the eyes 

 a little more distant from the base, the prothorax more parallel and some- 

 what less strongly rounded at the sides, the elytral suture very distinctly 

 longer than the prothorax and the abdomen almost as wide as the elytra, 

 more parallel, narrowing only very slightly toward tip. Length 1.8 mm.; 

 width 0.45 mm. Pennsylvania (Mt. Airy). 



There is still another variety before me from the Catskill Mts., 

 having the antennae a little more incrassate and with more trans- 

 verse joints apically. 



Dolosota sequax n. sp. Rather stout and subparallel, moderately shining, 

 the punctures as in the preceding, the reticulation of the abdomen coarse, 

 distinct and irregular; pubescence pale, decumbent; body and legs pale 

 flavo-testaceous, the head and an indefinite subapical abdominal cloud 

 piceous-black; head transversely subtriangular, distinctly inflated at base, 

 the eyes scarcely longer than the swollen tempora, rather convex and strongly 

 faceted; antennae rather long and stout though only feebly and gradually 

 incrassate, pale ochreo-flavate and bristling with long setae throughout the 

 length, the first joint stout, elongate-oval, the second and third of equal 

 thickness, narrower and shorter, the third shorter and more obconic than the 

 second, the fourth to tenth from a little wider than long to obviously trans- 

 verse, the last distinctly shorter than the two preceding; prothorax large, 

 transverse, narrowing slightly and with well rounded sides from base to apex, 

 very much wider than the head and distinctly wider than any part of the 

 elytra, evenly convex and unimpressed; elytra small, transverse, subparallel, 

 the suture not quite so long as the prothorax; abdomen at base about as 

 wide as the elytra, gradually feebly tapering and with feebly arcuate sides 

 thence to the tip, distinctly and rather closely, asperately punctured. Length 

 1.5 mm.; width 0.38 mm. Iowa (Cedar Rapids). 



Recognizable by the form of the head and structure of the an- 

 tennae. 



Dolosota secunda n. sp. Form, coloration and sculpture nearly similar 

 but more slender, the elytra largely but feebly infumate except broadly 

 toward the sides and apex; head not so large, similarly transverse but nearly 

 parallel, the tempora not more prominent than the eyes and distinctly shorter 

 than the latter, nearly straight; antennae nearly similar but darker, brownish- 

 testaceous, becoming flavate basally, the fourth joint almost as long as wide, 

 the outer joints only slightly wider than long, the last larger, gradually pointed 

 and fully as long as the two preceding; prothorax similarly large, convex 

 and of the same form, much wider than any part of the elytra, the latter small, 

 subparallel, the lateral sinuses at apex very feeble, the suture a little shorter 

 than the prothorax; abdomen nearly similar but more slender, a little nar- 

 rower than the elytra. Length 1.5 mm. ; width 0.34 mm. Iowa (Iowa City), 

 YVickham. 



The type is gummed with a moderate sized blackish-piceous ant,
