216 GEO. H. HORN, M. D. 



by Blanchard, which was alternately suppressed and revived by 

 LeConte. Finding no reason based on structure, or suggested by 

 convenience, I return it to where LeConte first placed it. 



1. L.. laneeolata Say. — Variable in form in the sexes, brownish to nearly 

 piceous, suhopaque ; surface alutaceous, sparsely clothed with elongate whitish, 

 or yellowish scales. Clypeus sinuate at middle, more distinctly J , margin rather 

 widely reflexed, densely punctured, scales extremely small, front rather more 

 roughly sculptured, the scales more hair-like in the males. Thorax not narrowed 

 at base, arcuately narrowed in front, the margin strongly crenate. with short 

 ciliiE ; surface closely not deeply punctate, each puncture with a scale, median 

 line smoother. Elytra not distinctly punctured, but with an imbricate surface, 

 the sutural costa distinct, the discal costse very feeble. Pygidium opaque, with 

 close, but shallow punctures and few hair-like scales % , or more shining, more 

 sparsely punctate, smoother near apex and sparse scales 9 . Metasternum densely 

 finely punctate, the hairs short, but dense. Abdomen moderately closely punc- 

 tulate, smoother at middle Avith numerous scales. Tarsal claws curved, toothed 

 near the base, tooth small %, larger J. Last joint of maxillary palpi cylin- 

 drical, not compressed. Length .52 —.68 inch ; 13 — 17 mm. 



Male. — Form oblong, nearly parallel, body winged ; metasternum 

 of normal length. Antennal club nearly as long as the stem. Second 

 ventral segment obtusely carinate at middle, third and fourth with 

 an elevated crest, higher on the fourth, fifth segment slightly concave, 

 emarginate at middle of posterior border. Pygidium broader than 

 long. Tarsi long and slender, the posterior one and a half times the 

 length of the tibia. Spurs of hind tibiae very slender. Scutellum 

 oval (fig. 7). 



Female. — Ovate, ventricose, apterous ; metasternum short. An- 

 tennal club much shorter than the funiculus. Abdomen simple. 

 Legs stouter than the male, the tarsi stouter and shorter, the poste- 

 rior not longer than the tibia. Spurs of hind tibiae shorter and 

 broader. Scutellum transverse (fig. 8). 



Variations. — When the specimens are perfectly fresh the scales 

 cover the surface very evenly; when they have been transported and 

 subject to slight abrasion the scales are partly removed along the 

 lines of the discal costse, so that on each side are three abraded 

 vittse. 



This species formed for Blanchard the type of Tostegoptera, was 

 recognized by Burmeister, but rejected by Lacordaire and LeConte 

 as based on insufficient characters. 



Occurs from Kansas to Texas.
