thorax, .16 mm. long and .22 mm. wide; mesothorax, .26 mm. wide; 

 abdomen, .14 mm. wide; antennae: i, 23; 2, 38; 3, 72; 4, 41; 5, 30; 6, 

 28; 7, 15; 8, 17; 9, 19 microns. 



Head as in //.. salicis Shull, but the eyes are dark reddish browi . 

 projecting prominently, spines between the facets very short. Ocelli 

 yellow, posterior ones contiguous with the margins of the eyes, top- 

 shaped with the pointed end directed posteriorly. Mouth cone as in 

 H. salicis. Antennae, segments i and 2 considerably lighter than the 

 body, apex of segment 2 nearly white, segment 3 yellow crossed by 

 two white bands below the middle and with a white apex, segment 4 

 varying from nearly as yellow as 3 to nearly as brown as 5-9, always 

 lighter at the apex than at the base, no circle of sensoria ; segments 

 5-9 light brown ; all segments, but especially I and 2, show transverse 

 markings like the reticulations of the body ; articulations between seg- 

 ments 3 and 4, 8 and 9, and sometimes 7 and 8 clear, others brown. 



Prothora.v as in H. salicis being about twice as long as head, sides 

 strongly convex, beset with short spines which are more conspicuous 

 at the angles. Mesothorax wider than metathorax. 



Fore wings reaching to tip of abdomen, costal margin bearing about 30 

 spines, fore vein with about 26 and hind vein with about 18 spines. 



Legs as in H. arisaemae Hood, femora concolorous with the body 

 except the apical third of the fore pair which are concolorous with 

 the fore tibiae, yellowish brown. Other tibiae brown but lighter on the 

 apical third. Tarsi brownish yellow. 



$ . .75 mm. long. Other measurements from 20 to 30 per cent, less 

 than those of the female. 



Described from numerous females and several males taken 

 from the blossoms of Aescnlns pavia at Gainesville, Florida, 

 in March, 1914. This species is remarkably intermediate in 

 many of its characters between H. salicis and H. arisaemae, 

 particularly in the lengths of the antennal segments. It has 

 the legs colored like the latter species, but on the whole is 

 more closely related to H. salicis, from which it differs in the 

 italicized characters. 



Euthrips tritici var. projectus n. var. (PI. II, figs. 7-10). 



9 . Size, i.oo to 1.25 mm. Measurements of head and thorax as in 

 E. tritici. Antennae: Segment i, 27; 2, 39; 3, 53; 4. 45: 5- 3^; 6, 43: 

 /, 8; 8, 10 microns. 



Color varying from clear straw yellow without a trace of orange 

 except at tip of abdomen (found in blossoms of yellow composites) to 

 a deep orange on thorax and abdomen ; never brownish yellow. Shape 

 and spines of head and thorax as in E. tritici. 



Antennae: Segment i concolorous with the head, with a long but
