than the prothorax, with widely scattered and very moderate punctures, 

 the antennae thick, still thicker apically; prothorax elongate, parallel, very 

 dark testaceous, with numerous well separated and very moderate punctures, 

 which also form a distinct and unimpressed series at each side of the smooth 

 line; elytra large, much longer than wide, piceous in color, slightly wider 

 and much longer than the prothorax, with unimpressed series of rather small 

 punctures, the sutural series somewhat broadly impressed, the second in- 

 terval very wide; abdomen but little narrower than the elytra, minutely 

 and closely punctate. Length 5.6 mm.; width 0.9 mm. Indiana. 



The single female in my collection represents a species near col- 

 laris, but stouter, of different color and with much larger prothorax 

 and elytra. 



Lathrobiella depressula n. sp. Nearly parallel, rather depressed, shining, 

 pale testaceous, the head piceous : black, the abdomen uniform throughout, 

 moderately dark reddish-brown and dull in lustre; head parallel, much 

 shorter though barely visibly narrower than the prothorax, with widely 

 scattered coarse punctures, becoming numerous laterally; antennae rather 

 long, moderately slender, not at all enlarged apically; prothorax longer 

 than wide, not quite so wide at base as at apex, with numerous somewhat 

 close-set and rather coarse punctures, dense in the series at each side of the 

 smooth line, the series notably impressed ; elytra distinctly wider and longer 

 than the prothorax, longer than wide, with slightly impressed series of 

 dense, uneven and rather strong punctures, except in more than apical 

 fourth, where the punctures, though close-set and strong, are confused and 

 not in the least lineate; abdomen densely punctulate, slightly narrower 

 than the elytra. Length 5.0 mm.; width 0.8 mm. New York (Catskill 

 Mts.). 



This species, also represented by the female at present, is widely 

 different from anything before described and may be placed at 

 the end of the series. 



Microlathra Csy. 



Microlathra lineiformis n. sp. Very slender, rather convex, polished, 

 pale navo-testaceous throughout and perfectly parallel, all the parts being 

 of equal width; head nearly as in pallid iila but narrower, the punctures 

 strong but remotely scattered; antennae rather short and thick, feebly and 

 gradually enlarged distally; prothorax elongate, just visibly narrower at 

 base than at apex, with the moderately strong punctures sparse and dis- 

 posed in a few uneven short series; elytra much shorter than the prothorax, 

 the straight sides distinctly diverging from base" to apex, the surface of each 

 with about two broad and feebly impressed, suboblique lines, and with 

 rather small, sparse and unevenly sublineate punctuation; abdomen some- 

 what shining, the punctures fine but not dense. Length 4.0 mm.; width 

 0.5 mm. Iowa (Iowa City), \Yickham. 



Resembles pallidida Lee., but smaller and very much more slen- 

 der; the single type in my cabinet is a female.
