tate, less coarsely so toward apex, and with three fine almost entire cariniiles, 

 narrowly impressed along each side of the suture toward base. Legs slender, 

 the posterior long, with the tarsi fully three-fourths as long as the tibiae. 

 Length 19.0-20.0 mm. ; width 5.7-6.3 mm.

The description is taken from three perfectly similar males, the 

 single female before me being slightly more robust, with more par- 

 allel elytra, in which the narrow sutural dash of black becomes very 

 broad, abruptly narrowed to the suture just before the middle, not 

 extending to the edges except at apex. The antennaa in the female 

 are scarcely three-fourths as long as the body but not much stouter 

 than in the male, and the posterior legs, and especially the tarsi, are 

 decidedly shorter. This species belongs near coraUinus Lee. 



CROSSIDIUS Lee. 



C. "blandi n. sp. — Narrow, cylindrical, shining, bright rufous, the head 

 and postpectus black ; elytral blue-black area extending from the base for a 

 short distance, then abruptly contracted, extending narrowly along the suture, 

 gradually becoming wider to the middle where it becomes parallel, extending 

 with two- thirds of the total width to apical fourth where it is abruptly widened 

 nearly to the lateral edges, thence extending broadly to and enveloping the 

 apex ; pubescence long, sparse, erect and cinereous throughout. Head very 

 densely, coarsely punctate ; antennae a little longer than the body in the male, 

 two-thirds as long in the female, slender. Prothorax wider than long, parallel 

 and evenly rounded at the sides, evenly convex, coarsely punctate, the punc- 

 tures very uneven, dense near the apex, sparse elsewhere. Elytra slightly 

 wider than the prothorax, a little more than tvvice as long as the head and 

 prothorax combined, each broadly and evenly rounded at apex without trace 

 of truncature, reentrant at the suture, the angles rounded ; disk very coarsely 

 punctate, the punctures everywhere distinctly separated and becoming but 

 slightly less coarse toward apex. Prosternum before the coxae very coarsely 

 punctate in the male, finely and inconspicuously so and less pubescent in the 

 female. Length 7.7-9-5 mm. ; width 2.0-2. 5 mm.

This beautiful little species is widely distinct from discoideus in 

 its smaller size, narrower form and sparse punctuation, especially 

 of the pronotum, and from pulchrior Bland — which does not appear 

 to be exactl}^ the same as discoideus — it differs in the uneven pro- 

 notal punctuation, and in the gradually and not abruptly anteriorly 

 narrow^ed black area of the elytra. In discoideus the elytra are 

 always feebly but perceptibly truncate at apex, and the pronotum 

 is scarcely ever devoid of the two subapical black spots, of which 

 there is no trace in hlandi. Four specimens.
