278 ENTOMOLOGICAL NEWS. [November, 



pidae, among which Mr. Ashmead has found many interesting- 

 species. A tiny Chalcid, with striped wings, was abundant every- 

 where on flowers and leaves, windows and walls. One rainy day 

 I counted forty of them on the upper sash of my bedroom win- 

 dow. It was one of the Encyrtinae, Isodromus montanus, Ash- 

 mead MSS. The genus, Mr. Ashmead tells me, is parasitic on 

 Chrysopa larvae, generally issuing from their cocoons. And this 

 reminds me that the green lace-winged fly of the summit which 

 I had seen year after year and occasionally collected, was this 

 Spring determined by Mr. Nathan Banks as Mcleotna signoretti 

 Fitch. I had never examined the species closely, taking it for 

 granted that it was Chrysopa oculata, or some other common 

 species. But it has distinct structural differences when compared 

 with Chrysopa, having the antennas more widely separated, and 

 between them a sort of horn or tubercle. Mr. Banks called my 

 attention to this in the one specimen I sent him last May, and 

 this season I took several more of the same insect. I think there 

 has been no record of its capture since its first description by 

 Fitch. Neuroptera are few on the mountain; I took two or three 

 species of Hemerobius, the little Leuctra tennis, which rolls its 

 wings up tightly when at rest like a Crambus, and Platyphylax 

 designata. Of Qdonata I saw only Diplax rubicundula this 

 season. 



Monday, the 8th, was one of the best days of the Summer- 

 warm, bright and still. Insect life swarmed everywhere, and my 

 bottles, boxes, stretching-boards and hands were more than full. 

 As usual, every one contributed to my store, and I am glad to 

 acknowledge here my obligations, not only to my fellow-natu- 

 ralists, but to all the kindly people connected with the hotel. 

 These took a warm interest in my collection and brought me 

 many good things. The engineer of the hotel, Mr. William 

 Colby, is a very observant and successful collector, and to him I 

 owe many of my rarest insects. It was he who brought me my 

 first specimen of Ibalia maculipennis, that large and odd Cynipid, 

 and he found for me also Adelocera brevicornis and Harpalus 

 varicornis, both new to my list. 



During the rest of my stay on the mountain the weather was 

 variable, sometimes fair, oftener foggy and wet. One evening 

 another entomologist arrived, a Coleopterist, from Boston. With 

 him was a young physician, not entomological himself, but an
