82 THE REPORT OF THE No. 19 



Two of the larvae which were found pupating on the 4th August had 

 changed to pupa by the 5th August, and the moths emerged on the 30th 

 August. Other moths emerged on the 18th and 25th August, and 2nd, 

 5th, 6th, 8th and 13th September. 



The pupa is 20 to 25 mm. in length, and 5.5 to 7.5 mm. in width, at 

 widest part; shiny, reddish brown, darker in the incisures; anterior third 

 of each abdominal segment distinctly pitted, posterior third minutely 

 pitted. Cremaster blackish, bearing two stiff spines, which are distinctly 

 hooked at ends. 



INSECTS COLLECTED AT LIGHT DUEING THE SEASON OF 1904. 



By J. D. Evans, Trenton. 



The writer having collected, at light, at odd times in 1901-2 and 1903, 

 usually commencing late in the season and then continued only intermit- 

 tently, this season a start was made on the 6th of May and continued uninter- 

 ruptedly, except when th© weather conditions were against it, such as rain 

 or extremely cold weather, and for ten days in August while the writer was 

 called away from town. 



On the whole the season was very wet and cool, frequent rains during 

 the whole summer, which invariably ended in extremely cool weather. 

 Rain fell on six days in the month of May, nine days in June, eleven in 

 July, seven in August, ten in September, and six in October up to the 21st. 

 many of the rainstorms being accompanied with thunder and lightning. 



In former years very many specimens of leaf hoppers and parasitic 

 Hymenoptera were taken, but this season very few of the former, and I 

 may say none of the latter. It was noted that exceptionally few insects 

 were observed coming into the house in the evenings, in fact, only upon 

 one occasion were they observed at all. Consequently the captures were 

 small, numerically, as compared with what they might have been if the 

 season had been warm and dry, as is usually the case. 



The trap was usually put out at dusk, and taken in the following morn- 

 ing between five and seven o'clock. Oftentimes there would be nothing 

 in the trap by 10.30 or 11.00 p.m., but in the morning almost invariably 

 " no matter how much appearances would indicate a blank, a number of 

 things would be found. 



All insects of the orders Lepidoptera, Coleoptera, Hemiptera, Hymenop- 

 tera and Diptera, except the numerous midges and phrygania flies, would 

 be assorted out each evening following the evening of capture, and one 

 specimen at least of each species pinned, and the number of duplicates of 

 that species indicated on a card, together with the date of capture affixed 

 on the pin and put away for future reference. 



In the case of rare moths all specimens would be spread, as also one 

 or two perfect specimens of the commoner species. 126 species have thus 

 far been named and classified. Many of the microlepidoptera yet remain 

 to be determined, as well as about 16 species of the noctuidae, etc. 



The following is a list of the captures, with the number of specimens 

 of each species, and the range of the dates of capture. The numbers are 

 after Dyar's List. 



787 Scepsis fulvicoUis, Hubner 2 sp., 28 August and 12 SeptemBer. 



798 Ctenucha virginica, Charp 2 sp., 20 June and 26 July. 



808 Hypoprepia fucosa, Hubner 1 sp., 6 August. 



851 Estigmene acrsea, Drury 4 sp., 12 June — 14 July.
