INSECUTOR INSCITI^ MENSTRUUS 69 



The production of the eyes posteriorly on the ventral sur- 

 face of the head is apparently a unique character in the 

 Idolothripidse, and with the thickened anterior margin of the 

 pronotum will serve to distinguish this species from those of 

 the genera Blaphrothri(>s and Dlcaiothrips. In the Phloeo- 

 thripidffi eyes of this same type have been noted in Haplothrips 

 tibialis and bellus, Crypfothrips dentipcs, bicolor, and gilvipcs, 

 and in Ommatothrips gossypii. 



Kleothrips atratus, new species. (PI. IT, figs. 3 and o.) 



Female (macro pterous). — Length about 4.9 mm. Color 

 coal black, with tarsi and articulations of legs very slightly 

 paler; antennal segments 1, 2, and G-8 dark blackish brown, 

 3-6 lemon yellow, 3 narrowly brown at apex, 4 brown in apical 

 third, and 5 brown in apical half ; wings clear. 



Head three times as long as width across eyes, widest at 

 basal sixth, strongly but gradually narrowed behind eyes and 

 slightly at base, the width behind eyes being 0.76 the greatest 

 subbasal width ; produced portion of head about 0.77 as long 

 as the width across eyes, broadest apically, sides parallel and 

 slightly irregular in basal half ; dorsal and lateral surfaces of 

 head transversely striate and with three or four pairs of 

 prominent lateral bristles in addition to several smaller ones ; 

 postocular bristles minute and widely separated, shorter and 

 weaker than those on cheeks, their bases much closer to eyes 

 than the length of the latter ; a second pair of slightly longer 

 and less widely separated bristles about two-fifths the distance 

 from postoculars to base of head ; postocellar bristles minute ; 

 anteocular bristles about half the length of eye. Eyes promi- 

 nent, bulging, about 0.21 as long as head, slightly narrower in 

 dorsal aspect than their interval and slightly longer on dorsal 

 surface than on ventral. Ocelli of posterior pair large, situated 

 slightly in front of middle of eyes ; anterior ocellus minute 

 and resembling the insertion of a bristle, situated at basal fifth 

 of produced portion of head. Antennae (PI. II, fig. 5) about 

 I.-") times as long as head, length and width of each segment 

 given below under "Measurements ;" segment (i slightlv pro-
