evidently though gradually so toward the apex, where they are 

 separated by about their own diameters; dorsal striae obsolete, 

 represented by fine carinae, the sutural attaining the apex but be- 

 coming obsolete near the base; fourth dorsal reaching the apical 

 third, joining the obsolete sutural at base; third to first dorsals in- 

 creasing in length, the last named entire; oblique humeral obsolete, 

 internal subhumeral extending from base to apex, cariniform 

 throughout; external subhumeral short, impressed. Propygidium and 

 pygidium more coarsely and closely, nearly uniformly punctured. 

 Body beneath coarsely, closely punctate at sides, minutely and 

 sparsely so at middle. Prosternum very feebly convex at middle, 

 the striae horizontal, diverging a little before and behind the coxae, 

 broadly arcuately uniting behind the prosternal apex; interstrial 

 area with a few minute punctures. Anterior tibiae quadridentate. 

 Length 3.5 mm.; width 2.8 mm. 



California. Described from a single example taken by Mr. 

 G. H. Field in the mountains on the western border of the Colorado 

 Desert. This is one of the finest and mcst distinct species in our 

 fauna. The posterior tibiae are scarcely as wide as the middle 

 ones, but are hardly narrowed apically. This fact, together with 

 the nearly flat prosternum, indicates a position between Horn's 

 first and second groups ; it may, however, with about equal propriety 

 be included in Horn's group IV. The rugulosity at the sides of the 

 thorax is not due to the increase in size or longitudinal confluence 

 of the punctures; the latter are scattered over and between the 

 rugulosities and remain about as minute and sparse as at the middle 

 of the disk. 



Saprinus ciliatoides, n. sp. 



Closely related to, and very like ciliatiis, but on comparison 

 with type of the latter seems distinct by itfe larger size and generally 

 sparser, more niibute punctuation. In the type the elytra are as 

 Horn describes them, "densely aciculate punctate at sides and 

 apex," the punctures well separated only in the baso-sutural region 

 and narrowly along the suture posteriorly. The punctures are 

 in general elongate, a tendency that is evident even where they are 

 sparsest. In the present species the punctures are everywhere nearly 

 round, very sparse and fine on the disk, and even where closest, 

 as at the sides and apex, they are rarely much closer together than
