HALIPLUS, Latr. (Type ruficollis.) 



A. — Thorax punctate without a basal impression. 

 H. fascial us. Aube, Spec, vi., 30, 18. — Ovate, fulvous, thorax deeply punc- 

 tate, disc smooth ; elytra deeply striate punctate, the punctures becoming finer 

 towards the apex, interstices sparingly punctate, variegated with black irregu- 

 lar spots, apex black. L. -16 inch. 



Middle aud Western States. Distinct by the entirely rufous thorax 

 and very finely punctate head. 



H. puiiotatiis, Aube, 1. c, 32, 19. — Very closely allied to the preceding, 

 but with the thorax black in front on the middle, head visibly punctate, front 

 narrow; elytra similarly variegated, but with the spots more confluent. L.-14 

 inch. 



Middle and Southern States. 



H. triopsis. Say, Tr. Am. Phil. Soc. ii., 106 — Very near to 22". punctatus, 

 and only separable by the broader front; similarly spotted, but generally 

 lighter, and with the spots more defined and much less extended. L. -13 — "14 

 inch. 



Middle and Western States. 



H. boreal is. Lee. Lake Sup., p. 212, 32. — Distinct by the more convex 

 eyes, elytra more deeply sinuate at the apex, shorter form; the thorax is 

 scarcely infuscate in front, the head rather closely punctate, sides of thorax 

 and elytra less deeply punctate, the elytral spots are as in triopsis, but ill- 

 defined and less visible. L. -12 inch. 

 Lake Superior. (Leconte.) 



H. concolor, Lee. Ann. Lye. v., 201. — Allied to the first three species, but 

 smaller, entirely fulvous, without black marks, punctuation less strong, head 

 sparingly punctulate. L. "12 inch. 

 California. (Leconte, Horn.) 



H. L«ewisii. sp. n. — This is the smallest species I have seen, and may be 

 known by the head infuscate behind, elytra not sinuate before the apex, and 

 with well developed markings, (suture black, and black dorsal vitta on either 

 side, between these are one or two spots connecting them), punctuation not 

 strong, interstices very sparsely punctate. L. *10 inch. 



Texas. 



H. eribrarius. Lee. Lake Sup., p. 212, 33. — Very distinct by the elytra] 

 strise not deeper at the base; thorax finely punctate, with deeper basal punc- 

 tures, head with a bilobed black spot on the vertex, color pale ochraceous or 

 sometimes nearly fulvous. L. -15 inch. 



Lake Superior. Dakota. 



//. nitens, Lee. (1. c.) is merely a paler variety; other specimens 

 marked H. subguttatus, Lee. MSS. are darker in color but not other- 

 wise distinct. This species has the prosternum plane, not margined at 

 the sides as in all the other species.
