COLEOPTERA OK BAJA CALIFORNIA. 39I 



Scarcely louj^er than broad . latus. 



Oue-half longer than In-oad. estriatus. 



With scf/dus I have united piinctnlata. These were 

 originallv described from uniques, and the character based 

 on size, which seems to be the only one separating them, 

 has entirely disappeared in a series of twenty. The name 

 Jatiis is proposed for obsolctus, as there is at present a spe- 

 cies with the latter name in Hemiptychus. 



Hemiptyciius robustus n. sp. 



Oblono- oval, moderately densely clothed with ochre- 

 ous pubescence which conceals the piceous color of the 

 surface. Antenna; pale. Head minutely punctulate. 

 Thorax minutely densely punctulate with coarse punc- 

 tures widely scattered but closely placed near the hind 

 ano-les. Elvtra similarlv punctulate, the sHghtlv larger 

 punctures more numerous and more evident near the 

 apex, the marginal stria? deep, extending from the apex 

 nearly to the middle. Body beneath similarly punctured 

 to the upper surface, the coarser punctures of the abdo- 

 men more abundant and more evident. Length, .18 

 inch ; 4.5 mm. 



A number of specimens of this large species have been 

 seen. At first glance they resemble estriatus, although 

 more coarsely pubescent. It is at present the largest spe- 

 cies known with the elytra striate at sides near the apex. 



Southwestern Texas, near the Rio Grande. 



The genus Hemiptychus threatens to be very trouble- 

 some. A number of species still exist without names, 

 but it has not been thought advisable to name any but 

 those necessary, in advance of anv general revision of 

 them. 



Ceracis similis n. sp. 



Cylindrical, castaneous, the elytra slightly darker at 

 base, glabrous, distinctly punctate. Antenna; pale, the
