Zyg^na hippocrepidis in South Hampshire. — I have much 

 pleasure in recording an almost pure colony of Z. hippocrepidis 

 (Stephens) for this district of Hampshire. In early July of this 

 year I collected casually a number of Zygana cocoons, which I 

 thought were ordinary filijjendnlcs, hoping to obtain varieties later 

 of that species. I was agreeably surprised, therefore, when no less 

 than 90 per cent, of the coccoons produced very fine and undoubted 

 Z. liipp)ocrepidis . Only 10 per cent, were true filipeiuhdcB. I have 

 no knowledge of a May-June emergence, as I have not been on this 

 particular ground at that time of the year. Such a high percentage 

 of liippucrepidis in late July strikes me as remarkable, as I have 

 always understood that the hybrid occurs chiefly in May aud June. 

 From my own observations I believe that hipipocrepidis not only 

 pairs with its own kind, but also that such pairings are undoubtedly 

 fertile, and therefore has the power of carrying on from season to 

 season a colony of its own. That the sexes of hippocrepidis do pair 

 I think most entomologists who have made its acquaintance are 

 agreed upon. As proof, however, I quote the following instance that 

 occurred to myself. It is invariably my custom to leave all insects 

 that emerge from pupae in my cages for twenty-four hours, so that 

 the wings may be perfectly dry before I introduce their owners to 

 the killing-bottle. And so with the hip)pocrepidis ; and after they 

 had emerged, which always happened during the early morning, and 

 had dried their wings, I always found the sexes paired freely some 

 time during the day, and one batch of ova that I kept for observation 

 produced larvae later. — A. T. Postans ; 148, Fawcett Road, Ports-

Notes on Insects in London Suburban Gardens. — The Tortrix 

 Moth Sericoris littoralis was very common in my garden last June. 

 It is generally referred to as a coast or salt marsh species, the larva 

 feeding on flowers of Statice armeria. Some Thrift in the garden 

 accounts for its presence. The larva is pale dingy green with a 

 shiny dark brown head and black plate on 2nd segment. Amongst 

 other insects taken and not usually associated with a garden was a 

 male of the fine dragonfly JEschna grandis. This is the only dragon- 

 fly I have seen in this garden. There are no ponds near, and I think 

 it must have come from Wanstead Park, a mile or more away. 

 Foenus jaculator : Several flying about flowers. The ovipositor of the 

 female is as long as the insect. This belongs to the Evaniidte 

 division of the Ichneumonidtc distinguished by the abdomen being 

 inserted upon the back of metathorax. Said to be parasitic on other 

 Hymenoptera. I ascertained the name by referring to Curtis's 

 ' British Entomology,' vol. ix, at the Guildhall Library. See also 

 ' Entomologist,' vol. xiii, p. 253. Pyrausta punicealis : Larva feeds on 

 garden mint, greenish with black spots, usually found on chalk 

 downs. Ilyponome^ita evojiy melius : Frequent on garden Euonyvms. 

 It is usually found on wild Euomymus or spindle-tree. Referring to
