344 MEMOIRS ON THE COLEOPTERA 



antennse (9 ) slightly longer than the body, the twelfth joint slender, 

 finely pointed, barely a third as long as the third, three-fourths as 

 long as the eleventh. Length (9 ) 10.0 mm.; width 2.7 mm. New 



Mexico (locality unrecorded) : brevicollis n. sp. 



Prothorax less abbreviated, never more than one-half wider than long. . 8 



8 Male with the well defined black area of the hypomera or inflexed 



flanks of the prothorax separated from the anterior margin by a 



sharply denned red band 9 



Male with this equally well defined black area solid to the apical margin; 



entire prosternum as in the preceding, deep black 10 



9 Prothorax moderately coarsely, very closely punctate, the impunctate 

 line variable but never well defined. Male with the antennse very 

 slender, two-thirds longer than the body, the joints decreasing very 

 slightly in length, twelfth arcuate distally, very slender, distinctly 

 longer than the eleventh; subbasal spots of the elytra well developed, 

 the submedian transverse, sometimes slightly prolonged posteriorly 

 on the suture, the subapical suboval, moderate, isolated or oblique 

 to the suture. Female with the antennae not less slender, a fourth 

 longer than the body, the last joint two-thirds as long as the eleventh 

 and very much more slender; subbasal elytral spots as in the male, 

 the two more posterior also similar but much larger, broadly uniting 

 on the suture and connected longitudinally by a black sutural line; 

 longitudinal distance between the spots much greater than their 

 own length. Length (cf 2,9 i) 11.5-12.2 mm.; width 2.8-3.3 mm. 



New Mexico (Jemez Springs) medialis n. sp. 



A Prothorax as in the preceding. Male with the elytra much shorter 

 and more parallel than in medialis, with the subbasal spots not 

 quite so large, the submedian very large, oblong, obliquely at- 

 taining the suture very broadly but not prolonged, the subapical 

 similarly large but rounded, broadly attaining the suture, the 

 anterior outline of the combined spots sinuate suturally; antennas 

 still more slender, barely one-half longer than the body, the outer 

 joints relatively much shorter and more rapidly decreasing, the 

 last but very little longer than the eleventh; hind tibiae unusually 

 coarsely punctate. Length (cf, 9) 9.5-12.0 mm.; width 2.6-3.0 



mm. New Mexico (Jemez Springs) bifasciata n. subsp. 



10 Prothorax similar. Male with the antennae almost similar through- 

 out, the subbasal spots of the elytra large, elongate-oval, the sub- 

 median very large, broadly attaining the suture, the subapical 

 similarly very large, the combined spots forming a large area which 

 gradually narrows to the combined submedian blotch; abdomen 

 finely, very closely punctate, the fifth ventral very broadly arcuate 

 at apex as usual but longer than in the preceding, a third longer 

 than the fourth; hind tibiae much more finely punctate. Length 

 (cf ) 10.0 mm.; width 2.7 mm. New Mexico (Jemez Springs). 



conjuncta n. sp. 



A Prothorax more coarsely punctate and a little more abbreviated, 

 similarly well rounded at the sides. Male elytra with the inner 

 of the subbasal spots much smaller than the outer, the very large 

 blotches formed by the confluent submedian and subapical spots
