of various British Insects. !?0 1 



far Is this from being the case that we find them actually forming 

 these particles into a funnel at the mouth of the cell, whilst in Odyn. 

 Antilope, as described by me in the preceding Part of our Transac- 

 tions, this is not the case. 



Trochilium crabroniforme. This rare Lepidopterous insect has not, 

 I believe, been found nearer London than Darenth Wood, M'here it 

 is recorded by Mr. Stephens to have been seen flying heavily along 

 in some profusion. Mr. Havvorth gives the middle of July as the 

 time for its appearance in the winged state, and Mr. Stephens says the 

 beginning of the month. It has however been discovered by Mr. 

 Stevens, junior, of King Street, Covent Garden, in the osier-beds on 

 the Surrey side of the Hammersmith suspension bridge, in the last 

 week of June, and that gentleman having kindly pointed out the spot 

 to me, I have had the gratification of capturing the insect. The 

 osiers are cut annually, and the stumjis not above afoot high, so that 

 when the young shoots grow up the bottom of the tree is completely 

 hidden. It is therefore not upon the trunks of the trees, as is the case 

 with the other species of this genus, {T?-och. bemheciforme, which is 

 found on the trunks of the aspen trees in Epping Forest,) but upon 

 the leaves of the young shoots about breast-high, that the specimens 

 which I have captured were seen. Here they sit sunning themselves, 

 the abdomen occasionally being raised and depressed ; on the least 

 approach of danger however they fall to the ground, and are easily 

 lost in the long grass. My specimens are males ; perhaps the other 

 sex is ditFerent in its habits. 



Foenus jaculator. This curious insect is to be observed in hot 

 sunny weather flying about an old wall at the Kingston end of 

 Wimbledon Common, in which Ostnia bicornis breeds. I have met 

 with them in this locality (first pointed out to me by Mr. Shuckard) 

 for the three weeks preceding the July meeting of this Society. 

 Their appearance on the wing is very remarkable ; the abdomen is 

 stretched out at full length and slightly elevated, and the hind legs 

 are also canned at full length, and close together, the Avhite tip of the 

 ovipositor rendering it the more conspicuous. It flies but slowly, 

 and Saint Fargeau states that it deposits its eggs in the larvse of 

 Hymenoptera which live in the ground in closed cells. In this in- 

 stance I should rather consider that the eggs are deposited, like those 

 of the cuckoo bees, in the nests of the Osmia whilst they are in pro- 

 gress of formation, rather than in the nest after it is completed. 



Tipula longicornis, Curtis. I captured numerous specimens of this 

 new and very striking species of Tipula during the first half of the 

 month of June, in the low and damp part of Coombe Wood. Some 

 of them were flying about the trunk of an oak tree, and I observed
