Falpomyia Jfavipes Mg. — On a IMay-fiy {Baitis sp.), Snailbeiich, Salop, 

 vii.1920. The May-fly was much larger than the ralpomyia. The latter 

 settled on its back in the air and inserted its proboscis into one of the May- 

 fly's eyes, through which it sucked. The victim was capable for some time of 

 walking about with its enemy on its back, but had been sucked dry before 

 morning. 



Falpomyia ? niyripes Mg. — A specimen collected by Lt.-Col. Yerbury at 

 Studlaud, Dorset, 2.vii.]y07, was pinned on the came card with a female 

 of Tanypus ytittipennis Wulp, probably indicating that it was feeding upon 

 the Tanypus.

Ilylastes attennatiis Er. a British Insect. — Some yeais back I found here 

 a specimen of a very small Hylastes on some white linen hung out to dry, and 

 put it aside as probably a starved H. angustatus. On Ma}' 12th of this year I 

 noticed a number of specimens of this genus, as well as other beetles, walking 

 on the stump of a felled conifer, and some of these were so small that I took 

 four of them, and as 1 had nothing to put them in with me, wrapped them in 

 some paper, in which they got smashed before 1 reached home. On comparing 

 the remains with H. angustatus I found suflicient difference to lead me to 

 believe them to be a distinct species, and, on looking into the literature, I 

 labelled them " H. attennatus Er. ? " As 1 was leaving home the next day 

 I asked my daughter to go to the stump to look for more ; she did so, and 

 found two agreeing with the others. Commuuder Walker was here in the 

 following month, and one day informed me that he had found several examples 

 of a very small Hylastes walking on uewly-Bawn spruce-tir planks in the well- 

 known timber-yard at Brockenhurst, as well as one found by sweeping under 

 spruce trees at Rhinefield. He now tells me that he has submitted the speci- 

 mens to Mr. Champion, who has conhrmed them as //. attetwatus Er. I think, 

 therefore, we may add that species to our British list. The genus is a dirticult 

 one, and H. attenuatus is treated as a variety of angustatus llerbst in the 

 Heyden-Weise catalogue of European Coleoptera. It is, however, smaller 

 than angustatus, especially narrower, and the punctures on the thorax are 

 rather larger and less crowded, so that the surface is not so dull there; the 

 setae on the elytra are longer and therefore more conspicuous. The stump on 

 which my specimens were found here is of spruce-flr, but the species is pro- 

 bably not contined to that kind of conifer. I'erris, who paid so much attention 

 to the insects of Pinus maritinia, records this species therefrou), as well aa 

 H. anyustatus and another species which he described as H. vaiiolosus. He 

 found them at work iu the Landes in the mouth of May, and considers it
