Oockrell (Trans. Amer. Ent. Soc, xxxvi, p. 201, 1910) who 

 stated that certain species of the Australian Paracolletes also 

 resembled the same Prosopis models, " The yellow dorsal patch 

 in the Prosopis is tegumentary, in the Paracolletes due to hair, 

 but the superficial effect is the same. To my astonishment I 

 find also an Ilalictus with the same coloration (the patch due 

 to hair), so similar to Paracolletes Jlavomaculatus that I had 

 no doubt of its being a close relative until I came to examine 

 it in detail." This species was described (^.c, pp. 201, 202) by 

 Oockrell from three ? specimens, from Macleay, Queensland, 

 as Halictus 2^'^''''^^^^^^^'^''^'*^^^ ^^^ ^^ ^^^^ probable that the 

 specimen exhibited was the S of the same species. 



A short discussion on the mimetic signification of this 

 exhibit took place, in which the President, Prof. Poulton, 

 Messrs. C. 0. Watbrhouse and G. A. K. Marshall took part. 



A NEW SPECIES OF Argynnis. — The Rev. G. Wheeler 

 exhibited two specimens of a new Argi/nnis, discovered in 

 June last by Mr. Harold Powell, F.E.S., at Lambessa in 

 Algeria. He stated that during a recent visit to Mons. 

 Charles Oberthur at Eennes he had seen a di-awer of this 

 species in which there was only one slightly aberrant specimen. 

 Mons. Oberthiir had given him four specimens of this species 

 which on the underside somewhat resembled A. advppe, var. 

 chlorodippe (shown for comparison) but the ^s were entirely 

 without the broad androconial patches on the nervures of the 

 forewings on the upper side, present in all forms of A. adijype. 

 Mons. Oberthiir named it auresiana. 



Cocoons of Norasuma kolga, H. Druce, spun under 

 NATURAL conditions. — Dr. W. A. Lamborn observed that 

 some cocoons formed by larvae of this species in captivity had 

 been previously exhibited by Professor Poulfcon, which, how- 

 ever, did not present quite the same appearance as those 

 formed under natural conditions. The specimens now ex- 

 hibited were formed by wild larvae under leaves and were 

 found in the clearing at Oni Camp. They gave a better idea 

 as to the mimicry of Braconid cocoons by the formation of 

 little bosses of yellow silk. He remarked that it is the rule 

 to find several cocoons under one leaf frequently as many as 

 twelve.
