distinj^uishc'd by its larger size, l)roacier form, shorter and more 

 rounded vertex, the brown vittac in the anteapieal areoles, tht 

 longer male jjygofers, and the angle on the margin of the last 

 ventral segment of the female. It has somewhat the aspeet of 

 scriptus l)ut is very distinet in having a mueh shorter vertex. 

 in the form of the last ventral segment of the male and in the 

 more angled valve.

This tiny species is very close to oshonii but it averages a 

 little sinallcT, the vertex is a little more angled, the transverse 

 vitta is crowded close to the anterior margin of the v^ertex and 

 consists of a pale cloud against each ocellus which may be ob- 

 scurely connected to a pale basal mark either side of the middle. 

 The anterior edge is white and calloused and is nearly or quite 

 twice interru]jted on either side forming five conspicuous white 

 marginal spots. The general colors in this species are ]jale, 

 largely obliterating the white areolar spots on the elytra. It 

 has been found only on the island of Jamaica, unless a series 

 from California in Xhv Ball collection belong here.

This is very distinct from any other known dark-faced 

 sjjecies by the short transverse male plates and the short trun- 

 cated last ventral segment of the female. In the male the 

 front is almost black; the vertex is a little more than right- 

 angled at apex and is obscurely marked, with the white apical 

 line distinct. The male is dee])ly colored as in frontalis while the 

 female seems to be paler than the female of that species, but 

 in both sexes the wliite areolar spots are well developed. I have 

 been unable to detect any characters by which to distinguish 

 abruptus, the type of which Dr. Ball has kindly sent me for 

 examination, from fuscifrons. This species inhabits Arizona 

 and California.

This species has not been recognized by later students and 

 from the short description I am unable to place it in my synop- 

 tical table. I append a copy of Stal's description:
