250 MEMOIRS ON THE COLEOPTERA 



allic, the coxae rufescent; head with rather prominent eyes, the stri- 

 oles moderate and oblique; antennae piceous-black, with two rufes- 

 cent basal joints, extending to about basal fourth of the prothorax, 

 the latter two-thirds wider than long, the sides very finely reflexed, 

 subevenly and moderately arcuate, becoming parallel basally; apex 

 sinuate, much narrower than the base and with rather blunt, not 

 very prominent angles; basal angles right, not rounded; surface 

 feebly impressed and with longitudinal rugulae along the apex, the 

 stria very fine, much abbreviated ; inner subbasal striole fine and 

 short, the outer impression small, feeble, sublinear and posteriorly 

 oblique; elytra one-half longer than wide and evidently wider than 

 the prothorax, arcuately ogival in almost posterior half; striae very 

 fine, impunctate, the scutellar moderate; lateral series rather widely 

 interrupted; sinus wide and shallow; intervals nearly flat, with but 

 faint traces of irregularity. Length (9) 7-8 mm.; width 3.3 mm. 

 Mexico (Salazar, Mex.), Wickham *consors n. sp. 



Body more broadly oblong-oval, the elytra more rapidly and obtusely 

 ogival behind 7 



7 Form oblong-oval, convex, shining, with very faint bronzy lustre; 

 elytra ( 9 ) but very slightly alutaceous; under surface polished, with 

 slight greenish lustre; legs, coxae and trochanters deep black; head 

 smooth and convex, with rather prominent eyes, the strides more 

 minute than usual, extremely short, fine and barely evident; anten- 

 nae black, slender, extending to about basal fourth of the prothorax, 

 the two basal joints obscurely rufous; prothorax but little more 

 than one-half wider than long; apex deeply sinuate, much narrower 

 than the base, with prominent though narrowly blunt angles, the 

 basal right and not rounded; sides moderately, subevenly arcuate, 

 rather finely but strongly reflexed and becoming subparallel basally, 

 the surface smooth, not notably depressed latero-basally, the inner 

 striole very small, fine, short and faint, the outer impression lying 

 anteriorly in a very indefinite depression, small and subobsolete; 

 elytra one-half longer than wide, not distinctly wider tha^i the pro- 

 thorax, ogivally rounded in apical third, the parallel sides feebly 

 arcuate; striae only moderately fine, somewhat groove-like, impunc- 

 tate, the scutellar long; lateral series more widely spaced medially 

 but not at all interrupted; intervals flat, feebly convex apically, the 

 sinus shallow. Length (9) 8.2-8.35 mm.; width 3.75 mm. New 

 Mexico (Fort Wingate), Shufeldt. Two examples. 



modulata n. sp. 



Form oblong-oval, convex, almost equally shining in the two sexes, the 

 elytra micro-reticulate in both but shining, with scarcely bronzy 

 lustre, the under surface black, not at all metallic; legs black, the 

 tibiae and tarsi sometimes rufescent; head but little more than half 

 as wide as the prothorax, the eyes only feebly convex, the strioles 

 well developed and coarse; antennae black, with two or three pale 

 basal joints; prothorax fully three-fourths wider than long, the apex 

 deeply sinuate, with prominent and rather sharply defined angles, 

 much narrower than the base, the sides evenly and feebly arcuate 

 from base to apex and finely reflexed, not becoming quite parallel
