with a pair of long, knobbed bristles on dorsum, and by the 

 number and disposition of the sense cones. It approaches the 

 genus Crvptothrips in several points of structure. The male 

 is of special interest in that the postocular bristles, instead of 

 those at the anterior prothoracic angles, are increased in 

 length, which is in marked contrast to a reverse tendency 

 shown in the other species. 



Phloeothrips (Hoplandrothrips) insolens, new species. (PI. v, fig. 4; 

 VIII, figs. 1-3. 



Female (uiacropterous}. Length about 1.7 mm. General color dark 

 blackish brown, with sparse, irregular, maroon pigmentation in head, 

 thorax, and abdomen, exclusive of tube; antenna; with basal half of seg- 

 ment 3 yellow, and pedicels of 4-6 yellow or gray ; tibiae and tarsi pale lemon- 

 yellow. 



Head about 1.5 times as long as wide, fully 2.6 times as long as prothorax; 

 sides subparallel, converging roundly to eyes, slightly diverging at base, 

 which is noticeably wider than greatest distance across eyes and without 

 evident neck-like constriction; lateral surfaces noticeably subreticulate, 

 each cheek with about four rather stout, dark bristles arising from short 

 tubercles; vertex subconical, produced and overhanging; postocular bristles 

 equal in length to eyes, dilated and truncate at tip; middle of dorsum with 

 a pair of pointed accessory bristles half as long as postoculars. Eyes about 

 one-fifth as long as head, subcircular as seen from above. Ocelli of moderate 

 size, equidistant; anterior ocellus borne at tip of vertex, posterior ocelli 

 opposite or in front of centers of eyes. Antennae about 1.3 times as long 

 as head, slender; segment 1 trapezoidal, broader than long; 2 scarcely 

 twice as long as broad; 3 clavate, about twice as long as its greatest width, 

 distinctly sinuate on inner side, pedicel curved slightly outward; 4 clavate, 

 subequalin width to 3, fully twice as long as wide, broadest beyond middle; 

 5 slightly shorter and narrower than 4, of nearly similar form; 6 and 7 ob- 

 long, pedicellate, truncate at apex, broadest about middle, 7 twice as long 

 as wide; 8 sublanceolate, briefly and very distinctly pedicellate. Sense 

 cones short, those on segment 3 less than one-third the length of the seg- 

 ment; formula: 3, 1-2; 4, 1-2; 5, 1-1+ 1 ; 6, 1-1 +1 ; 7 with one of dorsum near 

 apex. Mouth cone slender, nearly attaining mesosternum, labium broadly 

 rounded at tip, slightly surpassed by labrum. 



Prothorax a little less than 0.4 as long as head and (inclusive of coxae) 

 fully two and one-half times as wide as long; pronotum non-sculptured, 

 anterior and posterior margins nearly concentric; all usual bristles present, 

 slightly dilated and truncate at tip, anterior marginals short, half as long 

 as postoculars, other bristles subequal in length to postoculars, or the pair 

 at the anterior angles slightly shorter. Pterothorax slightly wider than 

 prothorax, sides straight and converging posteriorly. Wings uniform 

 brownish yellow, probably of normal structure, subapical fringe double for 

 about eight hairs. Legs rather stout, fore tarsi without trace of tooth.
