1924] A New Species of Dixa from California 45 
A NEW SPECIES OF DIXA FROM CALIFORNIA, 
By O. a. Johannsen. 
Cornell University. Ithaca, N. Y. 
The species described below was reared on May first, 1923, 
by Miss Alice M. Westfall from larvae collected from the surface 
of a pool formed by the water from a leak in an irrigation pipe 
across the street eastward from the Claremont (Cal) high school. 
In the key published in Psyche (30: 52, 1923) the species will 
find a place in the couplet with D. clavula Will., but differs in 
having the point of intersection of the radio-median crossvein 
with the petiole of the radial sector less than one-fourth the 
length of the crossvein proximad of the base of R4 A 5 while in 
clavula the intersection lies almost the length of the crossvein 
proximad of this point. Moreover the basal segment of the 
clasper in the last mentioned species is distinctly globose. 
Dixa aliciae sp. nov. 
Male. Head, antennae, proboscis and palpi brown, pro- 
boscis more yellowish below. Thorax including scutellum, 
yellow; mesonotum with three dull dark brown lines, the middle 
one divided by a hair line, the laterals abbreviated anteriorly; 
metanotum and sterno pleura brown. Abdomen yellowish brown; 
basal segment of clasper not globose, its mesal process nearly as 
long as the terminal segment, straight, slender, parallel sided, the 
apical fourth still more slender and curved like a plow handle; 
terminal segment slightly clavate resembling that of D. modesta 
but with longer hairs, especially apically. Legs brownish yellow, 
extreme tips of femora and of tibiae darkened, tips of hind tibiae 
slightly swollen. Fore basitarsus broken in the only male speci- 
men. Wings hyaline, veins brownish except the base of the 
radius which is more yellowish; a very faint suggestion of a 
cloud covers the radio-median crossvein while the petiole of the 
cubitus is margined posteriorly by a faint grayish line; the sub- 
costa ends slightly distad of the base of the radial sector; petiole
