tation maroon red, disposed in head, thorax and abdomen 
wherever they are shaded with brown and also along sides of

3 grayish at tip, 4 shading from yellowish gray at base to brownish 
gray apically, remaining segments successively darker, 5 and 6 
somewhat lightened basallv, 7-8 dark blackish brown; mid and

Trinidad; C. B. Williams; from faggots. 
Structurally almost indistinguishable from the North 
American Cryptothrips junctus Hood. The figures of that species 
given in the Canadian Entomologist, Yol. XLIV, p. 140, 1912, 
would serve almost equally well for this. The coloration, how- 
ever, is utterly different.

brown, head darker than thorax, abdomen shading to black in 
tube; legs yellow, femora and tibiae somewhat darkened with 
brown, mid and hind tarsi slightly darker; antennae with segments 
1 and 2 about concolorous with legs, 1 darker, 2 paler at apex;
