black; a broad fascia before and another behind the middle, and the 

 apex purplish or bluish black; the margin of the fasciae arcuate upon 

 each elytron, the convexity being towards base of elytra; the fas- 

 ciae sometimes interrupted at the suture (= var. interruptus Lee.) ; 

 surface densely cribrate-punctate. Body beneath, legs, and abdomen 

 clothed with long gray hairs, blue to blue black; the apical and the 

 first and second ventral segments usually broadly red at the sides; 

 the apical segment usually with a large discoidal black spot. Length 

 8.2-15 millim. (Elytral markings, pi. VI, fig. 30.) 



The onl)^ species in our fauna with elytral markings at all similar 

 to this species is simulator Horn, in the description of which some of 

 the differential characters are given. 



Var interruptus Lee. (Trichodes apivorus var. interruptus Lee, Ann. 



Lye. Nat. Hist. N. Y., v, 1849, p. 18.) 



Specimens from Westfield, Massachusetts, and Spring Hill, Ala- 

 bama, given the writer by Prof. Wickham are referable to this va- 

 riety. The Massachusetts specimen is quite small, being but 8.2 

 millimeters in length ; the anterior fascia is reduced to a large, rounded 

 spot on each elytron, the post median fascia is widely interrupted 

 at the suture but attains the flanks; the apex, which is a much lighter 

 blue than the fasciae, has its anterior margin narrowly but deeply in- 

 cised with red along the suture; in all other respects the specimen is 

 typical. The Alabama specimen has the elytra less deeply and 

 coarsely punctate than in the typical form, but this is very likely 

 merely an instance of individual variation, a specimen from Marion 

 County, Florida, being intermediate between this and the forms with 

 normal sculpture. 



Occurs in Florida, Alabama, North Carolina, New Jersey, New 

 York. District of Columbia, Massachusetts, Canada, Nebraska, Texas, 

 and New Mexico. 



Isolemidia cariniceps sp. nov. (PI. V, fig. 6.) 



Elongate, piceous black, feebly shining; thorax, sutural, and 

 basal half of lateral margins of elytra bright yellow; mouth and base 

 of antennae pale yellowish, five apical joints of the latter dusky; legs 

 pale; the anterior tibiae, medial femora near apex, and middle and 

 posterior tibiae at base and apex piceous; middle and hind tarsi in- 

 fuscate. Head with the large, prominent eyes slightly wider than the 

 elytra; eyes nearly contiguous in front; occiput and front with ob- 

 tuse but distinct carina; surface very finely densely punctate, clothed
