their own diameters. The form, colour, striae, prosternum, etc., 

 are virtually as in ciUatiis. Length 3.2 mm.; width 2.5 mm. 

 (Length of cilialus 2.5 mm.) 



Nevada, Las Vegas. One specimen. I have seen another, 

 apparently the same, placed with the type of ciliatus in the Le Conte 

 collection ; it was taken by Crotch near San Bernardino, California. 



Saprinus martini, n. sp. 

 Moderately robust, brownish piceous with faint aeneous lustre, 

 integuments polished. Head densely punctate. Prothorax ciliate 

 at sides, densely punctate in front and at sides, becoming rapidly 

 but not abruptly smooth in the baso-medial region; the posterior 

 margin punctate. Elytra moderately, strongly and closely punctate 

 throughout, except between the sutural and fourth dorsal striae, 

 the smooth area rather well defined but not sharply limited behind, 

 the punctures extending further forward within the fourth stria 

 than along the suture. First and second dorsal striae attaining, 

 the apical third, third and fourth dorsals sub-equal and shorter, 

 sutural entire and joining the fourth dorsal; internal subhumeral 

 oblique, continuous with the humeral, parallel with and as long as 

 the first dorsal; external subhumeral short, distinct from the 

 marginal. Propygidium and pygidium densely but not confluently 

 punctate, the punctures becoming finer at the apex of the latter. 

 Prosternum rather strongly convex but not compressed, the striae 

 divergent and terminating in foveae, which are more remote than 

 usual from the prosternal apex. Margin of front tibiae about 6- 

 denticulate, each denticle bearing a stout spinule. Length 2.4-3 

 mm.; width L8-2.2 mm. 



California. Described from two examples taken by Mr. J. O. 

 Martin in Palm Canyon, on the western border of the Colorado 

 Desert. This species is of the same form and general appearance 

 as the common fimhriatus; this latter, however, ha\ing the pro- 

 sternum compressed, belongs to a different group. Martini, by 

 its prosternal character, belongs to Horn's group YI, and by the 

 ciliated margins of the prothorax is nearest ciliatus. In the latter 

 the punctuation of the elytra is more aciculate, the second dorsal 

 stria shorter than the third, and the prosternal foveae are less 

 distant from the apex. 



Bactridium californicum, n. sp. 

 Similar in general appearance to striolatum, to which it is
