tristts) about August 1st, in immense numbers, almost stripping large 

 trees. They begin upon the outer edge of the leaf and eat all except 

 the inner midrib. They are very sensitive to disturbance, very lively 

 and are generally found with the hinder part of the body bent up over 

 the back, and holding by the forward pair of feet only. 



A great number of the insects were found flying about the trees 

 August 19th, about ten males to one female. The males are almost 

 wholly black upon the thorax. 



Nematus cliloreus, Norton. 



Variety $ . — The antennae piceous beneath toward the tip and the • 

 labrum white. 



Texas. One specimen. (Coll. Am. Ent. Soc.) 



Emphytus Itoliii. n. sp. 



9.— Length 0.56 inch.— Allied to tarsatus. Color shining black; antennae 

 black, with the three apical joints and a dot on the tip of fourth above white ; an 

 obscure line beneath; tip of apical joint black; tegulae white ; scutel black; 

 legs white, with their coxce, the four anterior femora, apical two-thirds of the 

 hinder femora, a spot at tip of two anterior tibise and the tips of the four hinder 

 tibise black; claws and tips of claw-joints black; wings smoky-hyaline; a white 

 spot at base of stigma. 



Texas. (J. Boll.) One specimen. 



Antennae more slender than in tarsatus and the head not so wide. 



Empliylus maonlatns, Norton. 



Larva.— (Riley, Prairie Farmer, May 25, 1868; American Entomologist, i,p, 91, 

 fig. 76. Packard Guide, p. 221, fig. 147). Feeds on the Strawberry leaf. " Length 

 0.60 — 0.65 inch. — Somewhat translucent. General color light dirty yellow, with 

 a glaucous shade along dorsal and subdorsal regions, inclining often to deep 

 blue-green on the thoracic segments ; minutely wrinkled transversely. Venter 

 light glaucous. Legs 22 (6 pectoral, 14 abdominal and 2 caudal), of the same 

 color. Head more yellow than body, with usually a dark brown spot above, 

 one nearly of the same size on the upper front and two smaller ones on each 

 side, joined by a brown line, the anterior spot being lower than the other; these 

 two are sometimes blended, and there is but a triangular spot on top of head. 

 The depth of shadiug on the body varies. 



Pupa. — A dirty glaucous color, the members being somewhat lighter in color 

 than body." 



These larvae form two broods in the year — in May and July. The 

 perfect insect appearing in April, May and August. They eat innu- 

 merable small holes in the leaves. When not feeding they rest, curled 

 up spirally, on the under side of the leaf. The eggs are deposited 

 in the stem of the plaut and cause it to swell a little. Jn some places 

 they have caused great damage to the strawberry plants.
