NOTES AND OBSERVATIONS. 



Aberration of Enallagma cyathigerum. — As Mr. Lucas was looking 

 at some of my specimens of K. cyathigerum, he noticed that the black 

 pterostigma was absent from the left hind wing of a male that was 

 taken in the New Forest in August last. Examination with a lens 

 shewed that the neuration at the tip of the same wing was also aberrant. 

 Though the pterostigma is so small, its absence from the wing is very 

 striking. Dr. Chapman suggests that the cause must be sought for in 

 an injury received during one of the earlier instars. — S. W. Kemp; 

 Notting Hill, January, 1903. 



Hilara viridis. — A number of years ago I found a new fly in 

 Jamaica, which Mr. Coquillett in 1895 described as Hilara viridis. The 

 insect was quite out of the known range of Hilara, and the green 

 colour was peculiar, but there was no other genus to receive it. Upon 

 receiving recently Mr. A. L. Melander's excellent monograph of the 

 North American Empididte, I became convinced that the fly belonged 

 to the Mexican and West Indian genus Lamprempis, Wheeler and 

 Melander, 1901. I accordingly wrote Mr. Melander, who kindly gave 

 me an example of Lamprempis, which I communicated to Mr. Coquillett, 

 who now assures me that my opinion is correct. The species will 

 therefore be Lamprempis viridis (Coq.) — T. D. A. Cockerell. 



CAPTURES AND FIELD REPORTS. 



PsociDiA AT Missenden, Bucks. — On Sept. 12th I had a day's 

 collecting at King's Hill, near Great Missenden, Bucks. By beating 

 in a small wood, which consisted mostly of conifers with a little oak 

 and ash, I obtained seven species of Psocidia. Of these, the most 

 striking and at the same time the most abundant species was Cfccilius 

 fiiscopteriis, Latreille. C. fiavidm, Stephens, was common, while a few 

 C. obsoletus, Steph., were met with. A single Fsocus lonyicornis, F., 

 was beaten from oak, and other species were Stenopsocus cruciatus, 

 Linne, Peripsocus ph(Bopterus, Stephens, Elipsocus fiaviceps, Steph. —

The Dragonflies of Epping Forest. — After a prolonged period of 

 cold winds and cold rains, which greatly retarded the appearance of 

 dragonflies and restricted their number, towards the end of May the 

 weather became warm and bright. On the 25th of that month we 

 made our first capture, a solitary male of Pyrrhosoma nymphula. This 

 event was followed on 1st June by a female Leptetnim quadrimacidatum. 

 being taken at rest ; the right hind wing was much aborted. On the 

 same morning we took immature specimens of Ayrion piwlla, of both 

 sexes ; we observed pairs in cop, on 22ud June. Ischniira eleyans, Anax 

 imperator, and LibeUiila depressa were all taken for the first time on 

 26th June, and several empty nymph-cases of A. imperator were also 

 found on the same occasion. On 9th July we took, at Walthamstow, 

 a solitary specimen (female) of Enallayma cyathigerum; we had considered
