bills {Physothorax disciger), Heterandrium uniannidatum, H. 

 longipes {Ijolyostichus longicaudis), H. nudiventre [C. hrevicaudis), 

 and Aepoceras iiijiaticeps (the female of which is A. emarginatus). 

 To these probably may be added Dioniorus sp. {Nannocerus 

 biarticulatus) and Plesiostigma bicolor [Plujsothorax annuliger). 



" In the Old World but one trimorphic species of fig-insects 

 has as yet been found, viz., Crossogastcr triformis, G. Mayr." 



Mr. E. B. Poulton read "Further Notes upon Lepidopterous 

 Larvae and Pupse, including an Account of the Loss of Weight 

 in the Freshly-formed Pupa." The paper included notes upon 

 points in the ontogeny of SmerintJins larvae, and a description 

 and figure of the bifid and hairy caudal horn in the newly- 

 hatched Smeriiithiis popull. The adult larva of Aclierontia atropos 

 was compared with that of Sphinx ligustri, and the as yet un- 

 known appearance of the former in earlier stages was predicted. 

 Hitherto unnoticed eye-like marks were pointed out in the terri- 

 fying attitude of Chcerocampa elpenor, and the terrifying attitude 

 of Dicranura vinnla was described, and its defensive fluid was 

 shown to be strong formic acid. An eversible gland was described 

 in Orgyia pudihunda, and the protection of Acronycta leporina 

 was explained by its resemblance to a cocoon and the darkening of 

 its hairs when full-fed. A valvular aperture in the cocoons of 

 Chloephora prasinana, &c., was described, enabling the imagos to 

 emerge. There were also notes upon Paniscus cepludotes parasitic 

 on the larva of D. vlnida, and tables showing the immense loss of 

 weight in newly-exposed lepidopterous pupae due to evaporation 

 from the moist skin. 



Mr. W. F. Kirb}' observed that Kennie (' Lisect Transforma- 

 tions,' pp. 298 & 299) quotes some observations of Reaumur 

 relative to the evaporation from pupae (Reaumur, vol. i., 

 pp. 371-373; Kirby & Spence, iii., p. 262). The transforma- 

 tions of Acherontia Lachesis, Fabr., and A. Styx, Westw., two 

 well-known East Indian species, have been figured by Moore in 

 his ' Lepidoptera of Ceylon.' It would be very desirable if 

 entomological draughtsmen would always make drawings of 

 lepidopterous larvae in their natural positions on their food- 

 plants ; drawings of larvae in which this was neglected were shorn 

 of half their value for scientific purposes. Mr. Kirby could not 

 answer Mr. Poulton's inquiry as to whether the Esquimaux had 

 any instinctive horror of snakes, but serpents played a considerable
