The angulate expansions of the pronotum and the comparatively large 

 size of this species give it the aspect of a Gargaphia. However, it has the 

 generic characters of Leptostyla. In this genus it needs to be compared 

 particularly with L. data Champion (Biol. Centr.-Amer. Heteroptera, 2, 

 p. 16, 1897). It differs from that species in the greater development of 

 the hood, the front declivity of which also is much steeper; in having 

 3 as the maximum and 2 as the minimum number of series of areoles in 

 the costal margin, instead of 4 and 3 respectively, and in having less dark 

 marking. 



From L. dilaticollis Champion (pp. 18-19), to which it is not so closely 

 related, it differs in having 3 long, diverging, instead of 2 short, converg- 

 ing spines on vertex; in the first antennal joint being more than 2^ times 

 as long as second; and in having the maximum number of series of areoles 

 in the costal margin 3 instead of 4. 



First and last joints of antenna, base and spot near apex of discoidal 

 area, a few veins in costal area and apical third of elytra fuscous to black ; 

 membranous parts of body hyaline, most of the veins testaceous ; legs and 

 intermediate antennal joints of same color. 



Numerous specimens obtained in Arizona in 1882 by H. K. 

 Morrison, all in National Collection. A female type and male 

 allotype have been selected. Both Uhler and Heidemann used 

 the cabinet name velifica for this species. Uhler also at one time 

 called it Gargaphia reticulata.

Length of an average specimen (excluding antennae), 2.24 mm.; length 

 of pronotum, .957 mm. ; width, .72 mm. ; greatest width of elytra, .957 mm. ; 

 length of antennal joints : i, .099 mm. ; 2, .099 mm. ; 3, .757 mm. ; 4, .18 mm. 



Form broadly oblong, constricted at humeri and again beyond discoidal 

 areas; hemelytra widening again behind. Superior median spine of head 

 long, ascending, then somewhat decurved, inferior median spines shorter, 

 in and up curved so that they and the superior spine to a certain extent 

 converge; lateral spines short, projecting straight forward along inner 

 orbits. Pronotum (disregarding posterior extension) heart-shaped, the 

 apex cut off by a line farthest advanced at anterior angles and middle, 

 sinuate between. Hood not conspicuous, paranota well reflexed, biseriate; 

 carinte moderately high, uniseriate, the lateral ones arched, the median 

 bisinuate. Costal area mostly biseriate; subcostal and discoidal areas 

 mostly triseriate.
