From their perfect agreement with description and figu!-e (PI. 

 2, fig. 28) of L. brevicornis, two specimens collected in the 

 Argus Mountains, California, April, 1891, by Albert Koebele are 

 assigned to this species. Specimens collected by Mr. C. A. Hart 

 at Brownsville, Texas, December 8, 1910, and November 21, 

 191 1, also are referred here. 



Key to the Species of Leptostyla.* 



A. Pronotum widest at about middle; paranota angulate velifer n. sp. 



AA. Pronotum widest behind ; paranota not angulate. 



B. Third joint of antenna shorter than pronotum; anterior third of 

 costal margin with two series of about equal-sized areoles ; 



elytra widest near base clitorics Heidemann. 



BB. Third joint of antenna about as long as pronotum; anterior third 

 of costal margin not with two series of equal-sized areoles ; 

 elytra widest near apex. 

 C. Form narrower ; elytra widest near apex ; anterior third of costal 

 margin with a single series of large rectangular areoles; cos- 

 tal cross-veinlets hyaline oblonga Say. 



CC. Form broader; elytra about as wide across discoidal areas as 

 at apex; anterior third of costal margin with an outer series 

 of large areoles and an interdigitating inner series of small 

 areoles; costal cross-veinlets dark, 



heidemanni Osborn & Drake. 



Leptostyla velifer n. sp. — Length of an average specimen (excluding an- 

 tennae and cephalic spines), 2.93 mm.; length of pronotum, 1.28 mm.; 

 width, 1.22 mm.; greatest width of elytra, 1.32 mm.; length of antennal 

 joints : i, .36 mm. ; 2, .099 mm. ; 3, 1.36 mm. ; 4, .33 mm. 



Antennse long and slender ; three long, diverging, sharp-pointed spines 

 on head, underneath the median one of which are two shorter laterally 

 converging spines. Paranota flaring, roundly angulate at middle, strongly 

 refiexed, so that rounded posterior angle is almost vertical to surface of 

 pronotum ; four rows of areoles at widest point. Hood oblong, wider and 

 higher behind ; carinse thin, high and distinct, the lateral ones, uniseriate 

 and simply arched, the median one with a single series of large squarish 

 areoles, the upper edge, higher in front, rounded at the ends and sinuate 

 in middle. Costal area with large areoles in from two to three series ; 

 subcostal with the same number of series of smaller areoles ; discoidal area 

 with conspicuously raised margin. 



Color stramineous; basal and terminal joints of antennse, eyes, non- 

 membranous parts of thorax, spots near apices of outer margins of dis- 

 coidal areas, and under surface, except edges of rostral sulcus and legs, 

 fuscous to black. Legs, intermediate antennal joints, edges of carinae, etc., 

 a few cross veinlets in costa and some in membrane testaceous.
