LYC.EXA II., III. 7 



If there happen to l)e three or four larvf\3 on one stalk, l^}- tlie time they are 

 mature tlie butls are nearly all drilleil. The small larval head is set on the end 

 of a long, extensile neck. (Fig. i'.) The hole eaten is just large enough to ad- 

 mit the head, and as the larva feeds the second segment is pressed hard against 

 the Inul, so as to permit the ntuiost elongation of the neck. By this means the 

 interior of the bud is wholly excavated. The second larval segment has its top 

 elevated, compressed, and bent forward, and at all stages, when the larva is at 

 rest, the head is withdrawn into this segment and quite concealed. (Figs, i, i*.) 



Immediately following Pseudargiolus comes Wetjlecta, flying in June, from 

 about the first of the month, and is on tlie wing four or five weeks. This form 

 is smaller than Pseudavyiolnx, hnt in general appearance is not essentially differ- 

 ent from it, and is therefore unlike Violacea. But though so similar, these two 

 forms are distinct in origin, Nerjhcta certainly in some degree, and prol)ably 

 altogether, being in direct descent from Violacea of April. Both these forms 

 are represented by a comparatively small number of individuals. 



After these June Nt'cjlecla have passed away, at intervals through the sum- 

 mer and fall to October, a few individuals wdiich miglit be either Pseudargiolus 

 or Neglecta, for aught that appears, differing in size, though none are so large 

 as the average Pseudargiolus of May, here and there are seen. Bnt there is no 

 general brood. These late butterflies lay eggs on Actinomeris squarrosa (Fig. 

 o, Lye. III.), and probably somewhat on A. helianthoides, one or the other of 

 which is in Hower for many weeks. I have also found a mature caterpillar on 

 the imported shrub Dimorphantus Mantchuricus, eating the tlower buds. 



The first clew to the history of any of these forms was through the fall butter- 

 flies, Mr. T. L. Mead, here at Coalburgh. in 1873, having noticed a female Neg- 

 lecfa ovipositing on A. squarrosa. On being shut in a bag over the plant it laid 

 many eggs. But the chrysalids proceeding from these eggs died during the win- 

 ter. From others, obtained from larva3 from same plant the next jear, there 

 emerged three Violacea in Ft'ln'uary, 1875. Again, in March, 1882, two Viola- 

 cea came from similar chrysalids. 



On all the plants, when the larvoB are ready to pupate, they fall to the 

 ground, and doubtless conceal themselves under sticks and stones. The mature 

 larva3 will drop at the slightest jar, though when younger they cling firmly. 



Such, then, are the generations of this species at Coalburgh. In other locali- 

 ties not much has been observed, or at least made known. In June, 1878, Prof. 

 J. H. Comstock, at Ithaca, N. Y., sent me several larvaj on flowers of Viburnum 

 acerifolium, wdiich probably came from eggs of Neglecta. At London, Ontario, 

 Mr. Wm. Saunders found larvae on Dogwood, 12th July, and five of tliem gave 

 JSfeglccki butterflies. Mr. Saunders relates that, on food failing, he gave the
