44. CALLIMOME KOEBELEI, new species 



Similar to Figure 23 



Easily separated from all other species by the delicate sculpture 

 of the dorsum and its obscure parapsidal furrows. 



Female. — Length 2.3 mm.; ovipositor 2.75 mm. Thorax delicate 

 green with a slight brassy tint on the anterior part of mesoscutum in 

 some lights. Head as long as wide; viewed from the front finely 

 reticulated and strongly depressed; face, below the scape, clothed 

 with very conspicuous white appressed hairs, a row of hairs border- 

 ing margin of eyes; scape attached much below the middle of front 

 and not extending more than three-fourths the distance to the median 

 ocellus; scape and pedicel greenish-brown; rest of flagellum clothed 

 with ochraeous pubescence; pedicel much longer than the ring- joint 

 and first funicle joint combined, the first funicle joint not more than 

 one-third as long as the second, the second about as wide as long and 

 the rest slightly longer than wide and gradually increasing in width 

 toward the tip ; ocelli a little more than one and one-half times the di- 

 ameter of an ocellus from the eye margin. Thoracic dorsum somewhat 

 flattened and microscopically transversely reticulately rugose on the 

 mesoscutum and the scapulae, sculpture exceedingly delicate; parap- 

 sidal furrows very obscure being indicated only by a delicate line; 

 cross furrow on scutellum not deep but well indicated by a difference 

 in the sculpture of the scutellum; reticulations before the furrow 

 more or less longitudinal or fan-like and behind the furrow trans- 

 verse; scutellar apex rounded apically; propodeum nearly vertical^ 

 shiny, and with a number of pits on the anterior margin on each side 

 of the middle; somewhat purpurescent with violet tinge ventrally; 

 coxae, femora, and tibiae fuscous, the femora behind somewhat green- 

 ish; hind coxae brown with violet tinge above; veins yellow; marginal 

 vein a little more than twice as long as the submarginal, the stigmal 

 vein sessile. Abdomen rather strongly compressed and darker than 

 the thorax. 



Male. — Length 1.5 mm. Body dark green; femora dark green the 

 tibiae fuscous. 



Type locality. — San Francisco, Calif. 



Host. — Cecidomyid gall on Baccharis pilularis De Candolle.

Described from 17 specimens reared from the above named host
