This genus as now restricted, with acuta Ball as type, 

 includes two species known only from Southern California and 

 Lower California, Mexico. The slender tapering cephalic 

 process will at once separate them from other groups. 



Key to the Species of Orgamara. 

 A. Cephalic process long and slender, nearly twice as long as the eye; the 



anterior tablet of the vertex longer than wide acuta Ball 



AA. Cephalic process broader and shorter, extending beyond the eye, but little 

 more than its length; anterior tablet of vertex rectangular, .reducta Ball

 Orgamara acuta Ball. Proc. Bio. Soc. Wash., Vol. XXII, p. 198, Dec, 1909. 



A short-winged, dark fuscous species with an extremely 

 long and slender cephalic process. Length 5-6 mm. 



Cephalic process long and slender more than twice as long as the 

 eye. The oblique carina meeting the margin of the cephalic process 

 about one-third the distance from the apex. Anterior tablet of the 

 vertex slightly longer than wide. The front narrow, elongate, over 

 one-half its length beyond the median line of the eyes. 



Color — Brownish fuscous, pronotum much lighter than scutellum. 

 Irregular reticulations on the elytra and about four irregular stripes on 

 the abdomen, lighter. Whole insect with a coppery reflection along the 

 median line. Face uniformly brown. 



This species is strikingly distinct from all others in the 

 group and may be recognized by its long, slender, pointed 

 cephalic process. Specimens are at hand from the region of 

 San Diego, California, and adjacent portions of Mexico. Sol- 

 itary individuals have been taken from the middle of June until 

 early August. They occur in open spaces in the chaparall, two 

 of them were beaten from Arctostaphylos but this may have 

 been accidental. 



Orgamara reducta Ball. 



Orgamara reducta Ball. Proc. Bio. Soc. Wash., Vol. XXII, p. 198, Dec, 1909. 



Resembling O. acuta, slightly smaller, paler, with a shorter 

 cephalic process. Length 4 mm. 



Cephalic process broad, less than one and one-half times the length 

 of the eye. Oblique carina meeting the dorsum at the middle. Front 

 broader and shorter than in acuta, the median line of the eye bisecting 

 its length. 



Color — Pale gray, mottled with fuscous. The carinfe on the vertex, 

 the central plate of the pronotum, most of the elytra reticulations and 

 four interrupted stripes on the abdomen creamy white. Front pale, 

 slightly sprinkled with fuscous.
