to the root and remained in a semi-torpid condition, sometimes coming out on warm days 

 and eating a little. On 13th October I found that it had pui)ated, and I was tbme is 

 possession of the complete life-history of the species. The chry-salis which was coutainai 

 in a light cocoon al^ut an inch long, made by catching a few blades of grass together uxki 

 lining them with silk, was almost erect and seemed to be kept trom lying against ih» 

 cocoon by a few strands of silk. Chrysalis six lines in length, head-case square in froaalt^ 

 eye-cases large and bold, between the eyes and on each side of thoni are tuft? of tawmy 

 hair, with which the thorax and abdomen are also invested. Wing, leg and antfinaa 

 cases smooth. Abdomen at 3rd segment covered laterally by the wing-cases and Bligbtilj 

 wider than thorax or eyes. On segments 4, 5, 6 of the abdomen, beneath, the proleg* of 

 the caterpillar are still visible. Meso-thorax tumid and bearing upon its anterior mar;;^ 

 behind the eyes two elevated tuberculated prominences, in front of whicli in the inrrow 

 between the pro- and meso-thorax is the opening of the thoracic spiracle. Wing-casM 

 extending to the middle of the 4th abdominal segment, from their apices the tongue-caBM 

 run free and disconnected to the posterior margin of the 7th abdominal segment. Tb«re 

 are also two shorter and wider cases which exceed the wings and run free to the postariOT 

 margin of 5th abdominal segment. These are probably the extremities of the caseB of 

 the metathoracic pair of legs. Upon the dorsal surface of the abdomen are two series ■off 

 small concave disks, a subdorsal anterior series and a lateral posterior series, one pair 

 upon each abdominal segment. Cremaster consisting of a few large rounded hooks. Tt*© 

 colour of the hea'l, leg- and antenna-cases, black. Wing-cases at first green and afterward^ 

 greenish-black. Pro-thorax black. Meso and meta-thorax brown. Abdomen light broiniiu 

 All grasses offered were eaten readily, Panicum CrusGalU and Triticum repem* 

 perhaps with the greatest avidity, and Plielum pratense with the least. 



Awblyscirlex Vialis, Edw. — This pretty little butterfly was caged on 9th in s. tomato 

 can, and the same day live eggs were secured, white shaped like those of C. Martda^ !bmit 

 rather larger. All were laid upon the green leaves of a cut down tuft of Avena slriaitcL 

 The young larva' hatched on 20th, pretty little white caterpillars with black heads. Am 

 soon as they were placed on a tuft of Poa jnatensis the> crawled up to the tip of a bTatis 

 and made a tent by drawing the opposite sides half way together with one strong strand 

 of silk. Here thfy remaine*] about five days, eating a little from the edge of the leaf «md 

 then disappeared. Their tuft of grass was left uncovered, and I think they were killed 

 by the dryness of the air. They should have been covered with a glass. 



yinoiiiaiies Icelut, Lint. — A female of this species tied upon willow (Salix corittil^a} 

 laid one beautiful greenish winged and netted egg on 10th July. This was the same js 

 had been foiir.d upon willow bushes in the open and supposed to belong to this species, ibnit 

 the origin of which was now proved. My young larva was unfortunately drowned •!■*:.» 

 days after hatthing. Mr. Scudder carried his to the third stage. The eggs are laid uj^kxi 

 the upper surface of the topmost leaves of willow bushes from six to eight feet from lias 

 ground, and were only found upon the willow above mentioned, which has rather rougfc 

 pubescent leaves.
