June, 1920.1 NoTMAX : CoLKOPTF.RA, X. Y. IS'.I 



Elytra one fifth longer than wide, om- half longer than the thorax; punctures 

 nearly twice the size of those on the thorax, separated by about their diam- 

 eters, interspaces slightly rugulose, shining; strongly impressed along the 

 suture from base to apical third. Abdomen slightly narrower than the elytra 

 at base, as wide at the apex of the fifth segment ; surface reticulate, very finely, 

 moderately punctate. Length, 1.9-2.25 mm. ; width, .5-.6 mm. Seven specimens. 



This species is an intermediate form between groups IV and V of 

 Casey's synopsis. It would be distinguished from dclicaliis Csy. by its 

 hirgcr size, narrower thorax, not transverse fourth antennal joint. 



Trogophloeus vespertinus new species. 



Form somewhat slender, rather depressed ; ])iceous, abdomen Ijlack, elytra 

 somewhat paler, three basal joints of the antenna: and legs brownish testa- 

 ceous. Pubescence pale, fine, short and dense. Integuments feebly shining; 

 head, thorax and elytra \ery finely, densely and shallowly punctate throughout, 

 elytra slightly more coarsely but no less densely. Head slightly transverse, 

 scarcely narrower than the thorax ; eyes large but only moderately convex, 

 coarsely faceted ; tempora slightly less prominent, broadly rounded, one half 

 the diameter of the eye ; frontal prominences strong, antenna: reaching the 

 base of the thorax, somewhat stout, second joint as long as the next two and 

 much stouter, fourth joint slightly transverse, fifth larger, quadrate, sixth to 

 tenth distinctly transverse, tenth one third wider than long. Thorax one fourth 

 wider than long, widest at apical third where it is just perceptibly narrower 

 than the elytra, sides rounded in front, nearly straight and convergent behind, 

 base slightly narrower than the apex; discal impression well marked, distinctly 

 divided ; apical angles obtuse but distinct, basal rounded. Elytra scarcely 

 longer than wide, one third longer than the thorax, scarcely impressed along 

 the suture at base. Abdomen as wide as the elytra at base, slightly wider to 

 the apex of the fourth segment which is distinctly the widest part of the body. 

 Length, 1.5 mm.; width, .35 mm. Two spccinwns. 



This species may be distinguished from T. volans by its smaller 

 size, stouter antenna; and wider abdomen. The thorax and elytra 

 are narrower than in T. inccrtiis Csy. or dclicatiis Csy. to which it is 

 evidently related. 



Bledius fracticornis Payk. 



The specimens at hand agree exactly with European examples. 

 B. (Iccct^livKS Fall is closely related to this species and perhaps 

 .synonymous with it. It has not been recorded heretofore from North 

 America.
