Tomoplagia kelloggi, new species 



Figures 99,a,b; 102, g; Plate 23, figure 18 



The writer received the type specimen of this medium sized species 

 as atimeta Hendel from the U. S. National Museum, but it doubtlessly 

 represents a well-characterized new species which has an entirely 

 different aggregate of characters than atimeta except for the large 

 opaque black spot on the anal vein, a common character for both

 the characters given in the key (p. 329). 



Male: Length 4.7 mm.; wing 5.3 mm. long and 2.1 mm. wide, 

 2.5 times as long as wide. 



Head entirely testaceous yellow, 0.86 mm. long, 1.36 mm. wide 

 and 1.13 mm. high. Eyes in profile obliquely situated, 0.85 mm. high 

 and 0.57 mm. wide, 1.5 times as high as wide; genae below eyes 0.18 

 and inferior part of postcranium 0.25 mm. wide, both relatively 

 wide. Ocellar plate behind posterior ocelli with small black dot. 

 Inferior part of cerebral plate raised. Oral margin of the impressed 

 mesofacial plate raised and prominent. Frons at vertex 0.61 and at 

 anterior margin 0.52 mm. broad, broader than one eye and medially 

 as long (0.52 mm.) as broad at anterior margin. Antennae and mouth- 

 parts reddish testaceous yellow, except for the reddish brown labella; 

 maxillary palpi wide sickle-shaped. Postpedicel wide-oval, 0.25 mm. 

 long and 0.18 mm. wide, as wide as genae below eyes and 1.4 times 

 as long as wide; seta bare, shining blackish, except for the testaceous 

 yellow basal third; more than three times as long as postpedicel. 



The major part of the cephalic bristles lacking; the three incurved 

 lower orbital bristles are brownish yellow, the outer occipital (=
