the sutures as in the genus Tragus ; basal segment black, broad at the 

 apex, bilineated, confluently punctured ; basal foveas of the second seg- 

 ment very deep, transverse, slightly oblique and strongly aciculate ; 

 the two apical segments clothed above with rufous pubescence, as well 

 as the ventral segments which are also rufous, shining. Length 11 — 

 12 lines ; expanse of wings 17 — 19 lines

A fine, large species, probably the same as Say's variety of his Ich. 

 devinctor with black scutellum and legs, but in that species the scutel- 

 lum is flat, the central area of the metathorax is large and subquadrate, 

 the abdomen more smoothly and finely punctured and the segments 

 not contracted at their sutures as in rtgnatrix. 



This species seems very close to Ich. grandis Brulle, but among a 

 dozen individuals I cannot find one with a yellow spot on the scutel- 

 lum, as is mentioned by Brull6. 



Ich. tibialis Brulle seems to be identical with Ich. devinctor Say. 



65. Ich. semicoccineus, n. sp. 



Black, face yellow, wings dark fuscous, abdomen bright rufous, central area 

 of metathorax moderate, transverse. 



M(de. — Head black, the face beneath the antennae, narrow frontal 

 orbits, clypeus, a spot on mandibles and the palpi yellow, the face with 

 a large black spot on its middle, sometimes reduced to a mere dot ; 

 antennge porrect, more than half the length of the body, black, brown- 

 ish beneath towards the tip, basal joint beneath yellow. Thorax black, 

 shining, finely and sparsely punctured ; scutellum slightly convex, 

 polished, black, deeply impressed in front; njetathorax somewhat sca- 

 brous, the elevated lines well defined, the central area transverse, mode- 

 rate, its margin smooth and shining. Wings blackish-fuscous, with a 

 strong aeneous reflection ; nervures and stigma black, the latter with a 

 pale spot at base; areolet 5-angular, slightly oblique. Legs black, the 

 anterior and intermediate tibiae yellowish in front. Abdomen elongate, 

 sublinear, bright rufous, opaque, the segments strongly incised ; the 

 basal segment black, slender, rather broad at tip, bilineated ; basal 

 foveae of the second segment deep ; beneath, the segments are yellow- 

 ish-ferruginous. Length 8 lines; expanse of wings 12j lines.
