Brownsville, Texas. 



This species differs from crucifera Lac, that is, the North Ameri- 

 can specimens identified as that species, in being shorter and conse- 

 quently more robust, the prothorax though finely but distinctly punc- 

 tate, the median basal lobe of prothorax not at all reflexed, more or 

 less distinctly so in the specimens of crucifera collected by myself 

 and others in Arizona, and the epipleural lobe is more subangulate. 



Cryptocephalus pinicolus new species. 



Narrower and a little more elongate than quadrimaculatus Say, prothorax 

 distinctly dark metallic blue, elytra black with a bluish tint, an elongate 

 humeral spot, extending inwardly to the fifth or sixth dorsal stria and a sub- 

 apical spot red. Head sparsely punctate with moderate punctures ; antennae 

 as in quadrimaculatus. Prothorax rather finely and sparsely punctate, punc- 

 tures larger near base. Elytra not as coarsely punctate as quadrimaculatus ; 

 intervals smooth. Pygidium coarsely and rather densely punctate with a more 

 or less distinct median carina. Abdominal segments two, three and four 

 closely and moderately coarsely punctate, each puncture bearing a very short, 

 pale hair. Last ventral segment of the female with a very large, deep, circular 

 fovea. Length 3.5 mm. 



Huachuca Mts., Arizona. 



Two of the few specimens are marked " beaten from pine." The 

 narrower and relatively more elongate form and the distinct dark 

 metallic blue color will separate this from quadrimaculatus or quadru- 

 plex. Specimens of quadrimaculatus especially those from the South 

 have at least the prothorax more or less blackish blue, but the form 

 of these is more robust and the elytral punctuation is more coarse. 

 The apical read spot is absent in one specimen. 



Cryptocephalus pubiventris new species. 



Similar in coloration to C. quadrimaculatus var. notatus Fab. but much 

 larger. Head closely punctate with moderately large punctures, median line 

 without punctures. Prothorax less transverse and relatively a little longer 

 than in the var. notatus; distinctly punctate, but punctures not close and 

 moderately large. Elytra with rows of moderately large, not closely placed 

 punctures. Underside densely punctate, except the first ventral segment on 

 which the punctures are less dense than on the following segments, clothed 

 with relatively long greyish white pubescence. Length 6 mm., width, across 

 the middle of elytra 3.25 mm.
