19. Bolothrips artocarpi , new species.

Female holotype: head and abdominal segments 5 to 9 black, thorax and abdominal segments 1 to 4 deep golden brown and blackened at the sides. Antenna! segments 1 to 4 mostly golden brown with distal half of 3 and much of 4 mottled with gray; 5 to 8 uniformly deep brown. Legs blackish brown with inner distal ends of all femora whitish to golden yellow; fore tibiae golden brown, middle and hind tibiae blackish brown. Wings washed with brown, darkened at bases. Prominent spines blackish brown.

Head only slightly longer than wide, cheeks broadly rounded and evenly narrowed to base; eyes fairly small and flattened on outer margin. Antennae one and one third longer than head, segments 3 to 7 pedicellate, 3 and 4 oblong conical, 5 and 6 broadly clavate, 8 clearly separated but broadly joined with 7. Postocular spines placed close behind eyes, pointed. Prothorax with a median, full length darkened line; with all normal spines present, pair at posterior angles long, pointed, others very short. Fore tarsi unarmed. Forewings with eight double fringe hairs. Tube two thirds as long as head.

Total body length 1.96 mm.; head length 0.25 mm., width behind eyes 0.22 mm.; prothorax length 0.117 mm., width excluding coxae 0.279 mm.; tube length 0.176 111111., width at base 0.073 111111. Antenna! segments length (width): III, 66 (31); IV, 60 (33); V, 56 (31); VI, 56 (31); VII, 36 (26); VIII, 23; total 330 microns. Length of spines, - postoculars 60 microns, 011 prothorax, midlaterals and those on anterior angles about equal, 26 microns; outer on posterior angles 76 inner 46 microns; 011 ninth abdominal segment 100 and at tip of tube 140 microns.

Mt. Alifan, May 21, on dead twigs of Artocarpus communis, holotype female, one paratype female, Swezey (5468).

This species has the general appearance of Hoplothrips hoodi Morgan in color and general appearance, according to Morgan's description, especially in the lighter colored proximal antenna! segments which become gradually darker and also because of the light color of inner distal tips of all femora. It appears however that the species should more properly be placed in the genus Bolothrips , and close to B. semiflavus Moulton [B. P. Bishop Mus. 0cc. Papers 15 (12): 147, 1939], which name refers to the color of the antennae. The species artocarpi may be separated from semiflavus by the rounded shape of the eyes

on the underside of the head, in se111iflavus the eyes are prolonged and extend backward on the ventral side.
