5. — Last dorsal prolonged, received in the fork of the greatly prolonged last 



ventral 6. 



Last dorsal with two long slender processes, receiving between them the 

 elongate last ventral ; the latter curved upwards in the arc of a circle, not 

 cleft at the tip, but obliquely flattened (or beveled) on the under side, and 

 pubescent; accessory processes slender, long, sj)iniform, directed obliquely 

 downwards and backwards, nearer the median line are two other stout 

 processes directed backwards and between them a small furcate object, 

 which is perhaps the intramittent organ. Length 3 mm. ; Md. ; one pair,

0. — Last ventral % large, broadly channeled, curved upwards in the arc of a circle, 

 furcate at tip, receiving in the fork the last dorsal which is narrow and 

 nicked at tip ; accessory processes not developed ; penultimate dorsal normal 

 in form. Piceous, head blackish, eyes large, antennae longer than elytra, 

 first joint testaceous, third scarcely shorter than fourth ; prothorax one-half 

 wider than long, narrowly margined, tinged with testaceous. Length 2.5 — 



3.5 mm.; L. Superior, and N. H 12. fuliginosus Lee. 



Last ventral testaceous, immensely long, narrow, bent sigmoidly upwards, 

 dilated into a broad and large deflexed terminal fork, which receives the 

 narrow deflexed last dorsal; penultimate ventral broadly emarginate; 

 penultimate dorsal greatly elongated, concave beneath, with a large lateral 

 deflexed marginal tooth near the hinder end. Black, eyes moderately large, 

 antennae stout, as long as the elytra, third joint a little longer than second, 

 shorter than fourth ; prothorax twice as wide as long, strongly margined.

Head black, convex, densely punctulate, eyes small ; antennpe slender, extend- 

 ing to end of elytra piceous, joints 2 — 4 nearly equal, first joint yellow. Prothorax 

 l)right yellow, not wider than long, transversely convex, sides narrowly margined, 

 front angles obliquely truncate. Scutel and elytra piceous, finely rugosely punc- 

 tured as usual, half as long as the abdomen ; abdomen yellow wiih last two dorsal

 strongly margined ; head densely punctulate, darker j)iceous, occiput feebly chan- 

 neled, eyes small, antennse stout reaching to the middle of the elytra, joints 2 — 4 

 nearly equal. Elytra nearly as long as the abdomen, three-fourths as long as the 

 wings, finely rugosely punctured. Differs from fragilis by sides of prothorax 

 straighter and angles better defined. Length 2.5 mm. ; Va.; one 9.
