daily from the 30th of May up to the 19th of June, 1872, ^vhen T counted 

 in all six males and fifteen females. Their ways are entirely those of a true 

 Anobium ; they gnaw their neat exit-hole in the same laborious fashion, 

 and often remain at its mouth for a while before quitting it for the first 

 time. If frightened in any way they sham death by drawing up their legs 

 and antenute ; left to themselves they readily take flight, both sexes being 

 provided with ample wings. The lively, cornute males may be seen rest- 

 lessly crawling over the gall, constantly investigating its woody polished 

 surface by means of their antennae, and ready to copulate with the females 

 directly the latter have made their appearance. On such occasions a 

 running match takes place between the contending males to get hold of the 

 new comer, and the most resolute male, that is to say the individual which 

 can stand perambulation the longest, effects its purpose. The relative 

 position of the sexes is precisely the same as with Anobium ; the male 

 while mounted, strokes the sides of the elytra and the underlying lateral parts 

 of the abdominal segments of the female with its quivering antenna3. The 

 female carries her partner about while copulation lasts, and even takes win^ 

 successfully with her burden. By isolating some couples from their restless 

 companions, I have ascertained that this act lasts seldom longer than an 

 hour ; in some instances I have seen the males quit their hold after less than 

 half-an-hour. The impregnated females re-enter the gall for the evident 

 purpose of oviposition, but I have not been able to make as yet sure of the 

 latter point. I have observed females make their way rapidly towards the 

 nearest aperture while still carrying their partners, the males being 

 ruthlessly and forcibly deprived of their conjugal rights at the entrance of 

 the burrows, the females dragging themselves into the openings in spite of 

 the counter-efforts of the males, which had no choice but to drop off. I 

 have not seen the males enter the burrows again after their first exit from 

 them, but the females I have noticed to go in and reappear again, though 

 not always through the same tunnel, but I recognized the individuals in 

 question by minute white paint marks, which I had previously applied to 

 their elytra. Two of the beetles outlived a week, the males generally dying 

 after having copulated once : the females seemed to be longer lived ; one 

 marked female remained in full vigour for ten days. Their ' frass ' consisted 

 of isolated brown suuff-hke grains."

" 0)1 some Variations of Neuration observed in certain Papilionida. 



" I beg to lay before the Society a few cases of aberrant neuration which 

 I have lately observed in certain insects in my collection. They occur in 

 four genera, viz., Papilio, Parnassius, Thais, and Synchloe (Butler). 



1°. Papilio Cloanthus. In all the specimens I possess (three) I find that 

 the first subcostal nervure anastomoses with the costal nerve. This is also
