to be a prevalent form in the dry season from May- August. For 1 

 which is (test)' Spuler) not the typical 5 form, might I suggest the 

 name ab. caeruleo-mfusa if it has not been previously described, {c)

 Euro})as-'-, we have : — (1) Decrease in spots, culminating in ^ taken 

 March 8th, 1903, which has on underside forewings only five spot in 

 the band and trace of the basal spots. On the hindwings only two 

 faint basal spots and the 1st spot of the band, which is nearest the 

 costal margin present. I have transitional forms with obsolescent 

 spots, and forms with wings on one side normal and on the other 

 obsolete or obsolescent. (2) Increase in size of spots. One ? taken 

 in April near Cairo has very large spots, a small spot on anal angle of 

 hindwing, band spots of forewing pear-shapedf, produced towards dis- 

 coidal field. — Philip P. Graves, Turf Club, Cairo, Egypt. Novembei-

A NEW ABERRATION OF Parnassius MNEMOSYNE. — At Berisal Oil the 

 Simplon Pass on July 3rd, 1901, 1 took one ? , and on July 11th, 1903, 

 two g s and one $ , of a form of P. nmeniosi/ne that has not yet been 

 described. The two black spots in the discoidal cell of the forewing are 

 confluent, and joined together by a thick bar taking the shape of a 

 dumbell. To this aberration I propose to give the name of halteres 

 (aXrypes)- Especially remarkable is one ^ . The semitransparent 

 margin is of normal length and rather narrow, the ground colour no 

 darker than in type. The upper of the two dumb-bell spots invades 

 the spaces between II and 11,, and between IIIj and IIL. There is, in 

 addition, a black spot in the centre of the hindwing discoidal cell. By 

 way of contrast to this wealth of black spots, the spot outside the dis- 

 coidal cell of the hindwing, is remarkably small, and fills only about 

 half the space between IIIi and III.,. — P. A. H. Muschamp, 20, Chemin 

 des Asters, Geneva. December 20th, 1903. 



Irregularity of neuration in Parnassius mnemosyne. — I have a 

 fair percentage of imagines of P. mnemosyne in which the nervures 

 are very irregular. In comparing two insects A and B, I find that in 

 A the termination of II is 8mm. from IIIj, and IIIi is only 2mm. 

 from III.2, whereas in B (fairly normal) II is 3mm. from IIIj, and 

 nil 3|^mm. from IIL. The nervures are often forked, thus, in one 

 insect IIL forewing terminates in a fork, and III^ hindwing branches 

 out into a fork, of which only one prong reaches the border. — Ibid. 



* Spuler's figure is a little inaccurate in one respect. The rings round the 

 black centres of each spot are yellowish-grey, not greyish-white. — P.P.G. 



+ In a very large ]3roportion of specimens the two spots nearest the inner 

 margin of the forewing in the band coalesce. — P.P.G.

OviPosiTioN OF Parnassius mnemosyne. — At Berisal, on July 11th, 

 1903, I caught between thumb and linger a $ oi Parnassius )iiiiemosj/ue 

 that appeared to be ovipositing. On examination I found an ovum in the 

 abdominal sac. I netted over 50 ? s for examination, and finally 

 found a second with an ovum in her sac. I afterwards found that 2 2s 

 out of a large number I had left overnight in my collecting-box, had 

 each dropped one ovum into her sac. In no case did the ovum adhere in
