COLEOPTERA OF BAJA CALIFORNIA. 42 1 



erect hairs. Legs roughly punctured with short hairs. 

 Length, .56 inch; 14 mm. 



This species so closeh' resembles /c/'rci'/Zr/c? that a spec- 

 imen sent me by Mr. Wickham covered with the argilla- 

 ceous coating so common in Asida was labeled farallela. 

 It has exactly the same form and facies, but differs in its 

 opaque surface and by the presence of a short additional 

 costa branchino- from the marofinal rido-e. 



Riverside, Arizona. Collected by Mr. H. F. Wickham. 



Asida connivens Lee. A short time since, I stated 

 that this species is the male of hifnrca. In the present 

 series it is shown that the only character of those men- 

 tioned by Le Conte for the separation of the two species 

 of any value resides in the prominent hind angles. How- 

 ever, in a somewhat related species, A. coiifinens, the 

 hind angles of the thorax are similarly prominent in the 

 male, and to that extent confirm the view expressed. 



A. HORRiDA Champion, Biol. Cent. Am., iv, pt. i, p. 

 500, pi. xxii, fig. 15, occurs in Texas near the lower Rio 

 Grande, the Mexican locality being Nuevo Laredo, Tam- 

 aulipas. It is probably best placed in our series near 

 sexcostata. The surface has short inconspicuous hairs, 

 the side margin of thorax reflexed as in hirsuta, each 

 elytron with tw^o feeble discal costa parallel with the suture. 



A. OBLiTERATA Champion, soc. cis., p. 493. This 

 occurs in southern Arizona. At first glance this species 

 would be placed near marginata, but the disc of thorax 

 is scarcely convex and the lateral margin not reflexed, 

 nor is there the median basal impression. 



EUSATTUS SECUTUS n. sp. 



Very like E. diibius, but a little more convex, oblong 

 oval, black, moderately shining. Head opaque, sparsely 

 punctate, clypeus nearly entire. Thorax rather more
