wings. Mounted specimens invariably have the head tipped slightly 

 downward, due to the forcing back of the mouth-cone by unavoidable 

 pressure between the coverglass and slide; and this has, of course, 

 affected the accuracy of the measurements and proportions given above, 

 and may be partly responsible for the apparent insertion of the antennae 

 below the vertex. 



Haplothrips maliflorls sp. nov. 



Female (macropterous). — Length about 1.6 mm. Color dark blackish 

 brown, with fore tarsi, apices of fore tibi», and third antennal segment 

 paler; fore wings clear, with the scale and the extreme base dark brown. 



Head about 1.26 times as long as wide, with sides slightly arcuate, and 

 nearly as wide at posterior margin of eyes as at base; vertex subconically 

 produced over base of antennae to far in front of eyes, the anterior ocellus 

 overhanging and much surpassing frontal costa; dorsal and lateral sur- 

 faces with faint, close, anastomozing striae and a few minute spines; 

 postocular bristles pointed, about 0.8 the length of eyes. Eyes small, 

 about 0.3 as long as head and 0.6 as wide as their interval. Ocelli 

 anterior in position, the posterior pair opposite anterior third of eyes. 

 Antennae twice as long as head ; segment 1 a little longer than wide ; 2 

 about 1.7 times as long as wide; 3 about twice as long as wide, inner 

 surface less arched than outer; 4 swollen, longest and widest in entire 

 antenna, about 1.8 times as long as wide; 5 nearly twice as long as wide, 

 obliquely truncate at apex; 6 nearly 2.4 times as long as wide, pedicel- 

 late, obliquely truncate at apex ; 7 about 2.5 times as long as wide, 

 broadest at middle, pedicellate, sides evenly arcuate; 8 subconical, with 

 length more than twice the width, firmly united to 7; sense cones short, 

 inconspicuous; formula: 3,0-1; 4, 2-2; 5,1-1-1-'; 6, 1-1-f'; 7 with one 

 on dorsum near apex; antennae concolorous with body, except segment 

 3, which is paler in general color and distinctly yellowish along middle 

 and at base. 



Prothorax along median dorsal line about half as long as head and 

 (inclusive of coxae) 2.5 times as wide as long, surface smooth; all usual 

 bristles present, pointed ; the two pairs at posterior angles about equal in 

 length to postoculars, the others much shorter. Wings distinctly nar- 

 rowed at middle, the fore pair rather broadly expanded along costal 

 margin near base, and with the scale and extreme base dark brown; 

 third subbasal bristle long, pointed, the others very much shorter; no 

 subapical accessory hairs on posterior margin. Tarsal tooth minute, 

 arising at a right angle. 



Abdomen only slightly wider than pterothorax ; tergite 1 almost smooth ; 

 tergites 2-6 very faintly striate with subreticulate, anastomozing lines; 

 distal tergites nearly smooth. Tube expanded basally, about two-thirds 

 as long as head, a little more than twice as long as basal width, and 

 slightly more than twice as wide at base as at apex. Bristles pointed, 

 terminal ones light brown and distinctly shorter than tube, others colorless. 



Measurements of holotype : Length 1.64 mm. ; head, length 0.223 mm.,
