COLEOPTERA OF BAJA CALIFORNIA. 373 



each side not reaching the apex or base, surface coarsely 

 and rather closely punctate, becoming cribrate at the 

 sides, sparsely hairy. Elytra narrower at base than the 

 thorax, sides gradually arcuately narrowing to apex, mar- 

 gin serrate, disc with rows of coarse and deep closely 

 placed punctures nearly as wide as the intervals, these 

 latter uniseriately punctate, each puncture with a black 

 hair; color yellow, marked with round black spots ar- 

 ranged in three rows, a sutural row of about seven spots, 

 the largest scutellar, a median row beginning at the 

 umbone, slightly sinuous, of six spots, a marginal row of 

 five spots, the anterior one slightly separated from the 

 margin. Anterior margin of prosternum trisinuate, at 

 middle coarsely and closely punctate, flanks with shal- 

 lower variolate punctures. Metasternum more coarsely 

 and closely punctate, denseh^ at the sides. Abdomen 

 coarsely not closely punctate, punctures equally placed. 

 Body beneath sparsely hairy, last ventral segment with a 

 double margin at apex, the additional edge forming a 

 plate projecting beyond the true edge. Length, .47 inch; 

 12 mm. 



The specimen before me is a male from Texas, given 

 me by Mr. Ulke. 



In addition to the characters given above, it will be 

 observed that along the basal edge of the elytra the sur- 

 face is more closely punctate. Among our species, 

 maculifera should be placed near amplico/h's, with which 

 it agrees closely in form and structural characters, although 

 a little flatter. The species is unique, as far as known 

 to me, in the style of elytral ornamentation. 



Mr. Waterhouse figures a form which he considers a 

 variety of dclectahilis Waterh., resembling guttifera, 

 above described, so closely that they are probably the 

 same, but it is not quite so clear that either is merely a
