absent. The back of the antcnnal stalk is more distinctly pubescent in 

 latreillella than in leuwenhoeheUn. I am not acquainted with nodosella, which 

 has been regarded by some as the $ of latreillella, perhaps correctly. 



I should be glad to know if anyone takes the species, to which 1 have 

 applied above the name latreillella, in England. Fiirther, it is customary for the 

 species of Heliodinidae to rest with the posterior legs not touching the ground, 

 but commonly erected over the back, though some only display this habit 

 occasionally (as Sc/i-recfcens^einin) ; I have never noticed this in ieMU'evi/ioe/ceZZa 

 (which is common here, but now over for the season, though double-brooded on 

 the Continent), but should be interested to leiirn if it has ever been observed ; 

 possibly the spinose under-surface of the tarsi may indicate a change of 

 ancestral habit. — E. Meyrick, Thornhanger, Marlborough : July 1st, 1915. 



A rare sawfly in Eppi7ig Forest. — On May 16th, 1915, 1 was fortunate enough 

 to obtain a few specimens of the interesting sawfly Dolerus triplicatus Kkig, by 

 sweeping Jiinciis in marshy ground near Loughton Camp, Epping Forest. In 

 company with it was the commoner species D. haematodes Schr., which is known 

 to feed on Juncus and other rushes. I identified the species provisionally as 

 X>. triplicatus from the material in the British Miiseum (Natiiral History), and 

 through the kindness of Mr. Gr. Meade-Waldo, a male and female were sub- 

 mitted to the Rev. P. L>. Morice, Avith the result that my identification was 

 confirmed. Mr. Morice pointed out in 1910 (Ent. Mo. Mag., XLVI, p. 154) that 

 the only British males seen by liim up to that time had the thorax entirely 

 black, but the Epping Forest series have the thorax coloured red and black in 

 both sexes alike. A jjair ( ^ , $ ) are now deposited in the National Collection, 

 and another individvial remains in my possession. D. triplicatus is evidently an 

 uncommon insect. It was stated by Cameron (Monogr. Brit. Phyt. Hymen. I, 

 p. 163, 1882) that the only British example he had seen was a male captured by 

 the Eev. T. A. Marshall, coloured like the female, and this specimen is now 

 preserved in the British Museum. A female, captured by Mr. A. J. Chitty at 

 Colchester, in May, 1907, is now in Mr. Claude Morley's collection (Entom. 

 XLIII, p. 284, 1910). I should be glad to hear of any other captiires of this 

 insect. — Harold E. Box, 88, Driu-y Eoad, Harrow, Middlesex : July 6th, 1915.

The writer of this article has published several very interesting papers 

 dealing with the early stages and biology of Diptera and Hymenoptera, princi- 

 pally the former, the larvae of which are the main object of his researches. 

 The Anthomyiidae are regarded here in the wide sense given to the groiip by 

 recent work. Their larvae can be divided, from an ethological point of view, 

 into four categories : and the members of each, though of diverse systematic 

 affinities, possess in common certain structural characters, which Keilin con-
