PSYCHE. 



525 



Mr. J.M. Aldrich, lately of Lawrence, Kan- 

 sas and formerly entomologist to the experi- 

 ment station at Brookings, S. Dakota, lias 

 been appointed entomologist to the experi- 

 ment station at Moscow, Idaho. 



Rtibsaamen has published in the Berliner 

 entomologische zeitschrift (v. 37) a system- 

 atic study of the Cecidomyidae of the Berlin 

 museum, accompanied by 14 plates illus- 

 trating the structure of the wings, abdominal 

 appendages, antennae, head, pupae and 

 : 'breast bone". They are divided into 2 sub- 

 families and 23 genera, 4 of them new; 80 

 species are considered. 



The first (double) number of the same 

 journal for 1893 is given up to the first instal- 

 ment of a description by Karsch of the insects 

 of Adeli, West Africa, consisting of the 

 Apterygota, Odonata, Orthoptera saltatoria, 

 and butterflies. 



Aldrich publishes in the first part of vol. 

 2 of the Kansas university quarterly a re- 

 vision of the N. American species of the 

 dipteran genera Dolichopus and Hygroceleu- 

 thus, 81 of the former (21 new) and 5 of the 

 latter (1 new). An excellent plate is added, 

 especially devoted to antennae. 



Moore's Lepidoptera Indica (part 15) is 

 still occupied with the Satyrinae; the early 

 stages of only one species are figured, but 

 the wet-season and dry season broods of eight 

 species are distinguished. 



PROCEEDINGS OF SOCIETIES. 



CAMBRIDGE ENTOMOLOGICAL CLUB. 



14 April, 1893. — The 178th meeting was 

 held at 156 Brattle St., Mr. S. Henshaw in 

 the chair. Mr. H. A. Morgan of Baton 

 Rouge, La., was elected to active member- 

 ship. 



Mr. S. H. Scudder showed the fossil fly 

 from Florissant which he had described under 



the name of Mycetopkaclus intermedins 

 Owing to a suggestion of M. Ch. Brongniart 

 of Paris he had re-examined the specimen 

 and found that he had been mistaken in re- 

 ferring it to the Mycetophilidae, since the 

 antennae are brief and not very long as he 

 had supposed and the relative stoutness ,,f 

 the legs showed that notwithstanding its ap- 

 parently spurred tibiae and small size it 

 belonged to the neighboring family 

 Bibionidae and to the genus Penthetria, an 

 existing genus already well-known in tertiary 

 deposits. 



Mr. A. G. Mayer remarked on the 

 lepidopterous fauna of the Bahamas which 

 he had just visited. All the species found 

 by him, with the exception of a Utetheisa, 

 are strong fliers, as the weak fliers are blown 

 off shore by the trade winds. Anosia plex- 

 ippus was seen as well as species of Pieridae, 

 Heliconidae and Hesperidae. The fauna and 

 flora seem derived largely from the United 

 States, though in part from South America. 



Mr. Scudder called attention to a recent 

 paper by Hampson on stridulation in 

 Lepidoptera and said he had heard a clicking 

 sound from Polygonia faunus on Mt. Wash- 

 ington, N. H. Mr. Mayer said he had 

 observed the same in P. interrogationis. 



Mr. A. P. Morse exhibited specimens of 

 the pupae and imagines of a moth found 

 feeding on woolens; also the opened egg 

 cocoon of a spider which in nature bore a 

 considerable resemblance to an oak apple. 



Dr. H. S. Pratt stated that he had recently 

 been engaged in studying the embryology of 

 the sheep tick. The head is developed in 

 the embryo but is concealed in the larva by 

 two imaginal disks, which are formed by 

 invagination on the dorsal side at some dis- 

 tance from the anterior end; they remain 

 latent during the larval state and in the pupa 

 are developed into the head. The larva 

 bears considerable resemblance to that of 

 the fly.
