near apex. Mouth cone slender, nearly attaining mesosternum; labium 

 broadly rounded at tip, slightly surpassed by lab rum. 



Prothorax somewhat more than half as long as head and (inclusive of 

 coxse) about 2.2 times as wide as long; pronotum non-sculptured, anterior 

 and posterior margins concentric; all usual bristles present, subequal, 

 dilated at tip, and about as long as postoculars. Pterothorax slightly wider 

 than prothorax, sides straight and converging posteriorly. Wings present. 

 Legs moderately slender; fore tarsus with a short, stout, acute tooth. 



Abdomen little, if any, broader than pterothorax, broadest toward base, 

 thence rounded gradually to base of tube. Tube about 0.6 as long as head, 

 about 2.3 times as long as basal width, and twice as wide at base as at apex, 

 sides straight. Lateral bristles of moderate length, knobbed, yellowish, 

 two pointed pairs at apex of segment 9 longer; terminal bristles about 1.5 

 times as long as tube, brown. 



Measurements of holotype: Length 1.68 mm.; head, length 0.276 mm., 

 width 0.212 mm.; prothorax, length 0.154 mm., width (inclusive of coxae) 

 0.341 mm.; mesothorax, width across fore margin 0.360 mm.; metathorax, 

 width across hind margin 0.312 mm.; abdomen, width 0.360 mm.; tube, 

 length 0.172 mm., width at base 0.075 mm., at apex 0.039 mm. Antennal 

 segments: 1, 30 M ; 2, 54 M; 3, 76 M; 4, 70 /x; 5, 63 M ; 6, 57 M; 7, 52 n\ 8, 34 M ; 

 total length of antenna, 0.44 mm.; width at segment 4, 0.033 mm. 



Described from 5 females, as follows: Pulaski, Illinois, C. 

 A. Hart, May 28, 1909, in sweepings from grass; Pulaski, 

 Illinois, July 24, 1909, C. A. H., in woodland sweepings; St. 

 Joseph, Illinois, May 4, 1907, C. A. H. and J. D. H., at base 

 of mullein leaves; Urbana, Illinois, January 26, 1908, J. D. H., 

 under bark of soft maple tree; "Millerstown, Pa., Sept. 6, 

 on fox grape." (Pa. State Dept. Agr., Div. Zool., No. 3668). 



Two males, both from Illinois, appear to belong with this 

 species, but show so much mutual variation in the form of the 

 fore legs that I have hesitated to include either in this pre- 

 liminary description. The species bears a resemblance to 

 Hinds's uzeli, but is easily separable by the much shorter tube 

 (which is not more than 0.6 as long as the head, instead of 

 nearly 0.8) and the longer, slenderer, and less abruptly sinu- 

 ate, third segment of the antenna, which in uzeli is not more 

 than 1.7 times as long as wide. This latter difference is illus- 

 trated in the accompanying figures (Pl.vi, figs. 5 and 6). 



Phlceothrips ( Hoplandrothrips) juniperinus, new species. (PI. VII, 



figs. 5, 6.) 



female (macropterous). Length about 1.5 mm. General color dark 

 blackish brown, with a rather dense, nearly continuous layer of maroon 

 hypodermal pigmentation in head, thorax, and abdomen, inclusive of tube; 

 antenna3 with basal two-thirds of segment 3, basal third of segment 4, 

 and pedicel of 5, yellow.
