220 GEO. H. HORN, M. D. 



Male. — Antennal club a little shorter than the stem. Abdomen 

 broadly flattened, the penultimate segment with a slightly granulate 

 space posteriorly. Inner spur of hind tibia stout, inserted at the 

 side of the end of the tibia, curved in a quadrant inward and down- 

 ward, outer spur small, triangular (fig. 12). 



Female. — Antennal club shorter than the funiculus. Spurs of 

 hind tibiae normal. Posterior tarsi distinctly shorter than in the male. 



Variations. — Like nearly all the reddish-brown species the color 

 may vary in intensity. The costee of the elytra are more distinct in 

 some specimens, and in these the surface seems more rugose, 



A very distinct and easily determinable s{)ecies of the male is at 

 hand, fortunately that sex is by far the most abundant. 



Occurs in Texas, Waco (Belfrage), 8an Antonio (Brouse). 



6. li. hamata n. sp. — Oblong, slightly broader behind, rufotestaceons, thorax 

 darker, head brown ; surface shining. Clypeus emarginate, margin narrowly 

 reflexed ; surface, with the front, closely punctate. Thorax narrowed in front, 

 sides feebly arcuate, margin distantly interrupted by the insertion of short cilise, 

 surface with moderate punctures ; regularly, not closely placed. Elytral punc- 

 tures similar to those of the thorax, but deeper; the discal costse scarcely visible, 

 the sutural well marked. Pygidium coarsely moderately closely punctate, 

 smoother at the sides and apex. Metasternum finely not densely punctate, the 

 hair moderately long, but not dense. Abdomen sparsely punctate, smooth at 

 middle. Legs more red in color, tibise and tarsi brown. Claws feebly arcaute, 

 the tooth moderate in size and intramedian. Last joint of maxillary palpi cy- 

 lindrical, not impressed. Length .66 inch ; 17 mm. 



Male. — Antennal club a little shorter than the stem. Abdomen 

 flattened at middle, the penultimate segment declivous at middle of 

 posterior half and slightly granulate. Inner spur of posterior tibiae 

 stout, strongly arcuate, arising at the end of the tibia, the outer spur 

 short and triangular (fig. 11). 



The unique before me superficially resembles ephilida, although 

 somewhat dilated behind, so that while related to torta, structural!}', 

 it is quite unlike it in facies. The curved spur of the male hind 

 tibia arises in a nearly direct line from the end and projects less 

 inwardly than in torta. 



One specimen, Texas. 



Group IV, ephilida. 



This group contains species of cylindrical form and compact build. 

 The head is rather broad. The clypeus is entire in one species, feebly 

 emarginate in the others. Antenme 10-jointed, club elongate in the
