 Five species represent this family, as follows : 



I. ANTHOTHRIPS GO^A^DEYI, new species. 

 Plate LXIII, fig. S; Plate LXIV, figs. 15, 10; Plate LXV, flg. 23. 



Female. — Length, 1.01 mm. to 1.73 mm.; width of head, 0.14 mm. 

 to 0.20 mm. ; width of mesothorax, 0.21 mm. to 0.33 mm. ; greatest 

 width of abdomen, 0.21 mm. to 0.35 mm. General color deep brown, 

 appearing irregularly mottled more or less with dark reddish or pur- 

 ple hypodermal pigmentation, especially the thorax. 



Head of about equal length and breadth, yet often somewhat wider 

 behind than in front; cheeks straight or very sligtly bulging behind 

 the eyes. Vertex somewhat elevated between the bases of the an- 

 tenna?. Dorsal surface finely cross striated. Eyes small, finely 

 faceted; ocelli quite large, much larger than the facets of the eyes, 

 and well separated, bordered medially by dark red pigment cres- 

 cents ; anterior ocellus placed far forward, almost touching the bases 

 of the antennse; posterior ocelli touching margins of eyes. Post- 

 ocular bristles long and knobbed at the end. Mouth cone reaching to 

 the middle of the prosternum, pointed, but Avith bluntly rounded 

 labium. Antennae about one and one-half times as long as the head, 

 with bases set very closely together. Relative lengths of segments as 



follows : 



J 2_ _3 4 5_ ^ J_ ^ 



6.8 9.8 10.8 12.2 11.8 9.3 8.9 6.4 



Most of the segments quite thick for their length, the fourth being 

 slightly thicker than any of the others, the third next thickest. 

 Segment one truncate, conical; two constricted toward the base into 

 a broad stalk, cut off squarely at end ; three slenderly stalked at base, 

 rather broadly rounded; four elliptical in general form, constricted 

 at base to form a broad stalk; five and six oval in outline and also 

 constricted at bases to form stalks ; seven barrel-shaped ; eight conical. 

 Segments one and two deep brown ; three and four yellow ; five yel- 

 low but slightly tinged with brownish on distal half ; six light brown- 

 ish yellow ; lighter at base ; seven and eight deep brown, concolorous 

 with the two basal segments. Spines weak; sense cones short, but 

 mostly rather sharp pointed. 



Prothorax subequal in length with the head ; broader behind than 

 in front; fore and hind margins nearly parallel, gently curved; pro- 

 notum bears on each side of its front part a pair of spines; of its 

 middle portion, a single spine; of its hind portion, a pair of spines; 

 all these are conspicuous and knobbed. Mesothorax somewhat wider 

 than prothorax ; sides of pterothorax nearly straight, but metathorax
