properly species different from coracina, will not improbably be 

 proved at some future time and with more evidence at hand. 



Cryobius Chd. 

 The following species is represented in my collection by a con- 

 siderable series : 



Cryobius washingtoni n. sp.^ — Elongate-oval, rather strongly convex, 

 black, polished, the legs bright rufous; head as wide as long, three- 

 fourths as wide as the prothorax, the eyes prominent; impressions rather 

 long, interrupted; mandibles and palpi rufous; antennae rather heavy, 

 somewhat more (cf) to less (9) than half as long as the body, nearly 

 black or paler basally; prothorax barely visibly wider than long, the 

 sides broadly rounded and finely reflexed, more oblique and very feebly 

 sinuate basally; base transverse, not margined laterally and as wide as 

 the sinuate apex having blunt angles, the basal right and very sharp; 

 median stria fine, not quite entire; transverse impressions moderate, 

 the anterior sharper and deeper; foveae linear in basal two-fifths, rather 

 deeply impressed and feebly punctulate; near the outer margin there is a 

 short punctate channel at base; elytra oblong-suboval, more inflated 

 and oval in the female, nearly three-fourths longer than wide, a fourth 

 wider than the prothorax; humeri not denticulate, the apices oblique, 

 more or less subsinuate; striae distinct and impressed suturally, fine to 

 subobsolete externally, finely punctate except apically, the intervals flat, 

 feebly convex suturally, the third with two to three punctures; anterior 

 male tarsi with the first three joints rather strongly dilated. Length 

 (cf 9 ) 7.0-8.0 mm.; width 2.4-2.9 mm. New Hampshire (White Mts.). 



I have had this species in my collection for many years under 

 the name hudsonicus Lee, but in the latter the elytra are apparently 

 less convex and the third interval has three to four punctures; the 

 legs are paler rufous in washingtoni. 



The following species I have had for some years under the name 

 confusus Mots., which was described from the Kurile Islands, but 

 it is evidently different: 



Cryobius patulus n. sp.^ — Rather stout, oblong-suboval, only moder- 

 ately convex, polished black above and beneath, the epipleura piceous- 

 black, the legs paler, rufo-piceous; head not quite three-fourths as wide 

 as the prothorax, the eyes moderate though notably prominent; anterior 

 impressions concave, feebly punctulate; mandibles dark, the palpi 

 pale, rufous; antennae blackish, paler basally, fully half as long as the 

 body; prothorax a fourth wider than long, widest before the middle, 

 the sides rather strongly rounded,, distinctly reflexed, with the gutter 

 deep but narrow, equal; toward the basal angles, which are right and 

 very sharp, the sides become feebly sinuate; anterior impression ob- 

 solescent, the posterior feeble, the median stria fine, impressed, biabbre-
