3. — Legs black, picoous or testaceous 4. 



Legs bright yellow 5. 



4. — Entirely black, side margin of prothorax very narrow about the middle. 

 Very similar to fraxini, but differs in the form of the claws and in the 

 prothoracic margin ; it is the analogue of the European atra Linn. Length 

 5 mm.; H.B.Terr.; Anticosti 9. Iligritlllus n. sp. 



Prothorax yellow, with a broad dorsal black stripe, side margin rather strongly 

 reflexed; legs piceous or testaceous. Length 4.5 — 6 mm.; Can.; 111.; Fla.

a. — Prothorax yellow, without dorsal stripe. 

 /?. — Elytra with entire margin pale. 



Black, only the sides of the prothorax yellow; prothorax wider than long, 

 disc not excavated each side near the margin, sides nearly uniformly rather 

 strongly margined ; elytra more coarsely and sparsely rugose ; claws with 

 a strong acute tooth ; antennae hailf as long as the body ; 9 • Length

5. — Piceous, mouth, prothorax, margins of elytra and legs j^ellow; antennte long 

 and slender fi. 



Antennae stouter; prothorax with a black cloud, wider than long, disc very 

 feebly excavated each side in front of the middle; side margin nearly 

 uniform in width; tibiae and tarsi dusky. Length 6.5 mm.; Ga. ; one 

 specimen ]2. criiralis Leo. 



Black, mouth, base of antennae, legs and prothoi-ax orange-yellow, the latter 

 with a black dorsal line, wider than longi disc broadly concave each side in 

 front of the middle, side margin strongly reflexed, nearly uniform in width ; 

 antennae rather stout, but little shorter than the body, second joint one-third 

 as long as the third. 9 antennae two-thirds as long as the body, second 

 joint nearly half as long as the third. Length 6 mm. ; 111. ; Ks.

fi. — Prothorax wider than long, disc broadly concave each side in front of the

or without a piceous cloud. Length 3.5 — 7 mm. ; Atlantic region.

 a. — Pale yellow above, elytral stripe wanting, nigriceps Lee. 



Prothorax not wider than long, disc more strongly concave each side before 

 the middle, sides subsinuate, margin strongly reflexed, narrower for a short 

 distance behind the middle; elytra with pale margin narrower. The type 

 specimens of this species are pale yellow, but the form of the prothorax 

 sufficiently distinguishes it from sritulus and is quite characteristic. Length 

 4—6 mm.; Va. ; Ga 15. piisilliis Lee. 



More robust, prothorax entirely yellow, one-half wider than long, sides 

 rounded, margin reflexed, of nearly uniform width; (approaches in form
