184 MEMOIRS ON THE COLEOPTERA 



Gyrophaena attonsa n. sp. Stout, moderately convex, polished, the 

 abdomen a little less so, pale testaceous, the head blackish-piceous, the 

 elytra more silvery-flavate, the fourth tergite feebly infumate in great 

 part; head very moderate, transverse, three-fourths as wide as the pro- 

 thorax, the eyes very prominent, the converging tempora behind them 

 very short; front with a few scattered coarse punctures between the 

 broad and subconvex impunctate and entire median line and each 

 eye; antennae short, moderately setose, pale, gradually and moderately 

 incrassate, the third joint much shorter and thinner than the second, 

 fourth and fifth not longer than wide, the outer joints slightly transverse, 

 the last as long as the two preceding; prothorax short and very transverse, 

 twice as wide as long, broadly and rather strongly rounded from side to 

 side at base, the sides parallel, much shorter than the median line, round- 

 ing anteriorly, the surface with two large foveiform punctures, placed 

 transversely at basal third and near the median line, also a few other finer 

 punctures widely scattered; elytra transverse, parallel, only about a 

 fourth wider, the suture a fourth longer, than the prothorax, having 

 only a few rather large and feeble indentations postero-externally; ab- 

 domen at base nearly as wide as the elytra, feebly, subevenly tapering 

 thence to the apex, with but just visibly arcuate sides, the punctures 

 basally rather numerous but extremely feeble and not well defined; sixth 

 ventral plate (9) acutely angulate. Length 2.0 mm.; width 0.63 mm. 

 New York (Catskill Mts.). 



This species has a large prothorax, almost as wide as the elytra, 

 as in vitrina Csy., but it is here shorter and more transverse, with 

 the sides shorter when compared with the median line; the head 

 is relatively smaller than in vitrina, the antennae shorter, less 

 setose, with shorter fourth and fifth joints and broader outer joints 

 and the two pronotal punctures before the middle, well deyeloped 

 in vitrina, are apparently obsolete. 



Gyrophaena criddlei n. sp. Rather stout, fusoid, moderately convex, 

 shining though with the micro-reticulation evident; color pale, the head 

 blackish, the pronotum gradually clouded medially, the elytra blackish 

 toward the external angles, the abdomen feebly clouded medially and 

 subposteriorly ; head transverse, four-fifths as wide as the prothorax, 

 with a few large but shallow scattered punctures at each side of the front, 

 the eyes very prominent, the tempora nearly half as long; antennae 

 pale, gradually very feebly infuscate distally, rather long, slender basally, 

 joints five and following forming a much stouter parallel loose club, 

 the third much shorter than the second, constricted basally, fourth 

 but little thicker, wider than long, five to ten fully as long as wide or a 

 little longer, the last but little more than one-half longer than the tenth; 

 prothorax feebly obtrapezoidal, nearly one-half wider than long, widest 

 and with the sides rather broadly rounded at about two-fifths from the 

 apex, the punctures rather small and shallow, the post-median central 

 pair feeble; elytra parallel, a fourth wider than long, nearly one-half
