Synhalonia hirsutior, n. sp. 
Male, length 12 mm.; black, with abundant pubescence all 
over the head and body, on the mesothorax so dense as to 
conceal the surface, but leaving the surface of the abdomen 
easily visible. Facial quadrangle broader than long; face, 
labrum and mandibles entirely black, but the clypeus appear- 
ing pale from the dense covering of long sordid white hair; 
hair of rest of head very pale ochreous, whiter and long on 
cheeks beneath; antenne entirely black, very long, a littie 
over 10 mm., flagellum crenulated beyond the middle, and its 
basal joints obscurely longitudinally ridged; fourth antennal 
joint more than three times as long as third; hair of thorax 
pale ochreous, orange-rufous dorsally; tegule reddish; wings 
almost clear, nervures very dark brown, second submarginal 
cell considerably broader than high; legs black, with whitish 
hair; abdomen black, with pale ochreous hair all. over, but 
longest on the first two segments. 
Hab. Banning, California. (Dr. A. Davidson). Easily 
known by the black face and labrum, hairy body, and very 
long black antenne. 
Melissodes menuacha, Cresson, var. semilupina, n. var. 
Male. Length 11 to 12 mm.,; similar to male menuacha, and 
with yellow spots on mandibles, but with the labrum not black 
at sides, and the red of the antenne darker. In Fowler’s table 
it runs to M. lupina, Cresson, and it has the color-characters 
observed by Mr. Viereck to separate lupina from typical M. 
agilis, but it is quite too large for lupina or agilis. It is, in 
fact, the Southern California representative of menuacha, dis- 
tinguished from the agilis forms by its larger size. A second 
specimen, also referred here, is a lttle smaller than the one 
just described, and has the fourth antennal joint shorter.
