714 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Argentine Galls.* — J. J. Kieffer and P. Jorgensen describe a large 

 number of interesting new galls from Argentina, mostly from the 

 province Mendoza. The galls are chiefly due to Cecidontyidas and 

 Tripetidae among Diptera, and to Lepidoptera. Two are due to Cyni- 

 pidae, two to Ghalcididae, two to Psyllid Hemiptera. Numerous new 

 hymenopterous parasites of the gall-makers are described — Chalcididas, 

 Platygasteridas, and Braconidae. 



Sensory Structures on Worker Bee's Mandible.t — Charles Janet 

 describes on the mandible of Apis mellifera, a variety of hair-like sensory 

 structures (" macrochetes," " microchetes," and "cones"), and also more 

 elaborate minute sensilli, protected by the setas and opening on the 

 cuticle by pores. 



Myrmecophilous Caterpillars.} — H.Yiehmeyer discusses the myrme- 

 cophily of the caterpillars of Gatochrysops cnejus Fabr. (from Manila), 

 and gives a list of myrmecophilous Lycasnidas of the Indo-Australian 

 region. Secreting pores in Gatochrysops furnish the attraction for the 

 ants (in this case Polyrhachis dives Smith) ; and there are also evagin- 

 ating tubes, which appear after the second moult. The tubes bear 

 bristles and may be tactile like the tufted hairs on the skin. Viehmayer 

 regards the appearance of caterpillars of Lycasnidas in ants' nests as 

 more or less accidental. 



In a subsequent paper § on a myrmecophilous Lycasnid chrysalis 

 from the Philippines, Viehmeyer deals with a species of Arhopala found 

 in a hanging nest of Gamponotus auadrisectus. When the nest was 

 broken, the furious ants grouped themselves around the chrysalids 

 (which lay within special cells) as if to defend them. The pupa seems 

 to act as a food -purveyor to the ants, giving them from a chitinous 

 crater the secretion of two glands, a sort of honeydew. 



H. Zerny|| gives an interesting account of those caterpillars, notably 

 of Lycasnids, which are found in association with ants. They are 

 protected by their companions, and in turn provide them with a delect- 

 able secretion. The author discusses some typical instances, and gives a 

 useful bibliography. 



Palsearctic Tortricidse.^f — J. Kennel continues his elaborate memoir 

 on this family of moths, dealing with Tortrix, Philedone, Epayoye, 

 Cacmcia, Anisotsenia, and related genera. 



Horn-feeding Lepidopterous Larvae.** — August Busck figures the 

 long horns of a large water-antelope (Gobus sp.), which showed striking 

 infestation with the curious larvae-tubes of a microlepidopteron, Tinea 

 vastella Zellar. There were large bunches of dark-brown finger-like 

 tubes about \ in. in diameter, -|— 2 J in. in length. These tubes are very 

 tough, being made of silk, with which earth and chewed horn are
