The fifth rentral segment is always very broadly impressed, the 

 impression deeper at the lateral extremities, appearing under certain 

 angles of reflection as if distantly bi-impressed ; this character ap- 

 pears to be independent of sex. 



N. piiberillus Lee. — Ann. Lye. N. Y., V, p. 145. — Oblong-oval, convex, 

 black ; head slightly rufous ; integuments smooth but rather dull ; pubescence 

 moderate in length, fine, sparse, recumbent and dark in color, not very con- 

 spicuous. Head t)-ans verse, feebly convex, deeply and broadly bilobed at 

 apex, some<vhat finely, moderately densely and asperately punctate, the punc- 

 tures not contiguous and almost granuliform ; upper lobe of eye very miniite, 

 much longer than wide ; antenn?e robust, much shorter than the head and 

 prothorax, the last three joints wider, third a little shorter than the next two, 

 eleventh almost circular, miich narrower than the tenth. Prothorax one-half 

 wider than the head and nearly one-half wider than long; apex much nar- 

 rower than the base, strongly emarginate in circular arc, the angles narrowly 

 rounded ; base transverse, gradually, feebly sinuate very near the sides, the 

 basal angles being slightly acute, not at all rounded and projecting posteriorly 

 beyond the median portion ; sides strongly arcuate, straighter in basal two- 

 thirds ; disk about equal in width throughout basal two-thirds, rather finely 

 piinctured, the punctures transversely arcuate, moderate in size, rather sparser 

 toward the middle, denser laterally, asperate throughout. Ehjtra ovate, very 

 little wider than the prothorax and slightly more than twice as long, but little 

 longer than wide ; sides distinctly arcuate ; humeri obtusely rounded ; disk 

 finely, somewhat densely and evenly punctate throughout, with vague traces 

 of series of widely distant punctures of the same kind. Abdomen rather 

 strongly, asperately punctate toward base. 



Male. — Not determined. 



Length 4.8-5.5 mm. ; width 2.5-2.7 mm. 



California (Vallecitas) Cab. LeConte ; (San Bernardino) Mr. 

 Dunn. 



The specimens before me exhibit no sexual impression toward the 

 base of the abdomen, but have the fifth segment strongly bi-impressed 

 as usual. The under surface and legs are rufous, the latter pale. 



IV. Sll'bstriatus n. sp. — Oblong, somewhat robust, black, rather strongly 

 shining ; legs and antennje rufous ; pubescence nearly as in puherulus. Head 

 transverse, bilobed at apex, somewhat coarsely, densely punctate, the punc- 

 tures very strongly granuliform ; upper- lobe of eyes very minute ; antennje 

 nearly as in puherulus. Prothorax aboiit one-half wider than the head and one- 

 half wider than long ; apex much narrower than the base, feebly, evenly 

 emarginate in circular arc, the angles narrowly rounded ; base transverse, 

 extremely feebly sinuate near the basal angles which are right, not rounded 

 and extremely feebly, posteriorly prominent ; sides evenly and rather strongly 

 arcuate throughout ; disk very distinctly wider in the middle than at base,
