51. CALLIMOME ROHWERI, new species 



Figure 19 



Closely allied to Oallimome thalassinum (Crosby) but is separated 

 by a distinct difference in the sculpture of the thoracic dorsum and 

 in color, rohweri having a distinct bluish tinge. 



Feinale. — Length 2.75 mm.; ovipositor 1.3 mm. Thoracic dorsum 

 distinctly reticulately punctured and with a decided bluish-green 

 color; abdomen deeply and widely reticulated, bluish. Head trans- 

 verse, a little wider than the thorax and anteriorly produced; trans- 

 versely rugose below the antennae, but vertically rugose between the 

 eyes; face clothed with very weak silvery hairs which are longest 

 near the margin of the mouth; antennae attached below the middle 

 of head and separated by a short carina; scape yellow beneath, green 

 for about two-thirds its length, cylindrical and reaching to median 

 ocellus; pedicel blackish green, the rest of flagellum black; pedicel 

 almost as long as ring-joint and funicle joint combined; ring-joint 

 about twice as wide as long; ocelli and eyes reddish brown; the pos- 

 terior ocelli one and one-half times the diameter of an ocellus from 

 the eye margin. Pronotum and mesoscutum finely reticulately 

 rugose, the parapsidal furrows black and well defined; furrow be- 

 tween the mesoscutum and scutellum very deep; anterior of the scu- 

 tellum with more minute reticulations than the posterior portion, the 

 rugosity on the scutellum more or less longitudinal instead of trans- 

 verse; posterior part of mesoscutum more deeply punctate than the 

 anterior; scutellar cross furrow well defined though not deep, the 

 scutellar apex somewhat shining; metanotum and propodeum smooth, 

 feebly reticulate, a few moderate-sized pits on the anterior margin; 

 coxae and femora dark bluish green, except at the tips and inside, 

 which are brownish; tibiae mostly ferruginous, bluish green in the 

 middle outside; tarsi yellowish to light brown; wings moderately cili- 

 ate, veins yellow; the marginal vein two-thirds as long as the sub- 

 marginal, the stigmal vein sessile. Abdomen mostly dark green with 

 a bluish tinge, the first segment green and shining, the others metallic 

 green with purplish margins; first three segments deeply incised; 

 viewed from the side somewhat rounded and tubular; ovipositor as 

 long as abdomen. 



Male. — Length 2.3 mm. Scape dark green, all joints of flagellum 

 wider than long; lateral ocellar line about equal to the ocellocular 

 line; legs brownish with a slight greenish tinge. Abdomen depressed.
