California. A fine female emerged one day during my absence from 

 home, and the males of S. cecropia congregated in such numbers on 

 the outside of the vivarium in the evening as to alarm my family, the 

 noise of their fluttering wings on the glass being mistaken for fire. My 

 boys caught 50, and said there were "hundreds more." David

Steganoptycha Claypoleana. 



Through the courtesy of Prof. E. W. Claypole we recived this spring 

 from Mrs. L. H. Lewis some iarvpe of the buckeye stem-borer noticed 

 in the November 1882, issue of \.\i^ American Naturalist (p. 914), and 

 have obtained therefrom a number of perfect moths. The general re- 

 semblance of some of the specimens to others of proteoterus cesculana 

 is great; but with the perfect specimens the differences upon close in- 

 spection becomes quite marked. Claypoleana' IdLck"^ the notch in pos- 

 terior borders of primaries, the tufts of raised scales on the disc of 

 same, and the peculiar tufts or pencil of hairs on the upper 

 surface of secondaries in the 5 , between the margin and the 

 costal vein. It is a shorter, broader-winged species; the ocel- 

 late spot is less distinctly relieved, the median oblicjue band more 

 broken, the basal-costal portion paler and contrasted along the 

 median vein with a darker shade, which maybe almost black, and wliich 

 broadens posteriorly till near the middle of wing, where it is ab- 

 ruptly relieved by a pale space obliquing basally. By these characters 

 the species is easily distinguished from (csculana, and it is withal a 

 greyer species with the pale and dark shades more highly and abruptly 

 contrasted. In an article by Prof. Claypole, which appeared subse- 

 sequent to our note (Psyche, III., p. 367, issued Dec. 16, 18S2), he 

 states that Prof. Fernald referred the species provisionally to Stegan- 

 optycha, Stephens, and this reference is evidently correct. 



None of the larvae we received were boring in the leaf-stem, but 

 rolled themselves up in the green leaves upon which they fed. It is 

 doubtless more of a blossom and leaf feeder than a stem-borer. The 

 larvae were feeding during the first half of May, and the moths issued 

 during the first week in June. C. V. Riley. 



Mating of Cecropia and Cynthia. 



This spring, having a $ Cynthia, and wishing to obtain some eggs,I 

 tied her out in my yard to mate. What was my surprise in the morn- 

 ing to find her attached to a ^ Cecropia. She laid a number of eggs, 

 but only four of them hatched. After nibbling for a while on linden 

 and ailanthus, the young larva died, very much to my sorrow. I turned 

 out some cynthia some years ago, and now the species is very common in 

 our city. ^ G. R. Pilate, Dayton, Ohio, 



A New Zyg^nid. Triprocris Martenii. n. sp.

Color uniform dull black, not so brassy as T. Smithsonianus; thinly 

 scaled, so that the veins show prominently. Primaries slightly produced 

 apically. Discal cell pedicelled, of the ten short veins given off from
