On the white Eucleidae and the larva of Calybia slossoniae, H. G. Dyar (Jour. 

 Xew York Ent. Soc, 5 (1897), No. 3, pp. 121-126, pi. 1).— The 5 species of Calybia noted 

 are distinguished as follows: C. immaculata by the inside of the primaries being 

 entirely white; in all the others this side is partly gray, especially along the costa. 

 C. slosso7ii(v is to be distinguished by the primaries being white above and by a yel- 

 lowish spot near the angle in the male. C.pigmcea has white primaries and shows a 

 distinct zigzag yellowish brown mark above the anal angle. C.fumosa instead of 

 entirely white has a subterminal smoky band on the primaries, and in C. jamaicensis 

 the secondaries are gray above instead of white, as in the last 3 forms. The two 

 species, Leucophohetron argentiflua and L. agyrorrhaa, are distinguished by a laro-e 

 dark spot above the anal angle of the wings of the former species and by the wings 

 being immaculate white in the latter. 



On the habits of Coccinella 7-punctata, K. Sajo (Illus. Wchnschr. Ent., 2 (1897), 

 No. 34, pp. 529, 530). — Cannibalistic habits are noted, also that the larva feeds on 

 Cochylis ambiguella and in all probability on Lema melanopsus.

 No. 29, pp. 45 1-456, Jigs. 26).

 pp. 465-469). 



On the post alar membrane of Diptera, E. Girschner (Illus. Wchnschr. Ent., 2 

 (1897), Nos. 34, pp. 534-639, figs. 8; 35, pp. 553-559, figs. 5; 36, pp. 567-571, figs. 7; 37, pp. 

 586-589; 38, pp. 603-607, figs. 2; 41, pp. 641-645, figs. 23). 



Nocturnal larva hunting, (Sciienkling-Prkvot (Illus. Wchnschr. Ent., 2 (1807), 

 Nos. 31, pp. 487-492; 32, pp. 502-505).— Mostly short descriptions of larva' to be found 

 during the several spring and summer months. 



A curious case of protective coloration, T. D. A. Cockerell (Psyche (1897), No. 

 260, p. 154). — The pupai of Pyrantels cardui are so colored as to be hidden in blossoms 

 of Bailey a multiradiata. The larva> feed only on Solanum elceagnifolium and seem to 

 warder to the blossoms of the other plant to pupate. 



A principle to observe in naming galls. Two new gall-making diptera, W\ 

 H. Patton (Canad. Ent., 29 (1897), No. 10, pp. 247, 24S).— The principle consists in 

 writing the name of the genus of the host plant with the name of the genus of the 

 gall makers, connecting the two with a hyphen. Applying the principle the author 

 changes the names of the galls described in the Fifth Report of the United States 

 Entomological Commission to Cecidomyia-celtis ovi/ormis, C. semcnoumicis, C.pubescens, 

 C. capsularis, and C. spiniformis. The new species are (Edaspis-solidago atra, the 

 galls of which do not differ from those of (E. polita, and Cecidomyia-celtis (new genus) 

 deserta. The galis of the latter are hollow elongate swellings of young twigs from 

 which the flies emerge about the first of June. 



Gall wasps of oaks, C. Keller (Jour. Suisse Econ. Forest., 1896, No. 2). 



Chinese insect white wax, G. F. Smithers ( U. S. Consular Bpts., 1897, No. 203, 

 pp. 484-490). — The best of the insects (Coccus pe-la) that produce white wax are found 

 in the Chien-Ch'ang Valley. Those from elsewhere bring a lower price, where they 

 are found on the evergreen, Ligustrum lucidum, which has various local names, as 

 ch'nng shu, or insect tree ; tung ching shu, or evergreen tree ; and pao-ke-ts'ao shu, 

 or crackling flea tree. The insects from Chien-Ch'ang Valley, found for the most 

 part near the town of Te Chang on the Au-ning River (latitude 27° 24'), are trans- 

 ported to the plain north of the Ta-tu River north of Chien Ch'ang, where they are 

 placed on the wax tree, Fraxinus chinensis, known to the Chinese as the pai la shu. 

 One pound of the scales produces 4 to 5 lbs. of wax. The process of obtaining the 

 wax is described. 



Renewing of queens, Devauchelle (V Apiculteur, 42 (1898), No. 1, pp. 14-17). — 

 The author's practice is to destroy few queens, and only those manifestly poor layers 

 or otherwise bad. It is not necessary to renew them every three years.
