Abnormal abundatice of Typhhcyba ubni L. iyi Hyde Park. — Pedestrians, 

 whether entomologists or otherwise, passing through Hyde Park between 

 Alexandra Gate and The Magazine on the morning of October Oth, could 

 scarcely fail to notice that the air appeared to be full of little, drifting, whitish 

 specks. Some of these specks, alighting and resting for a moment on tlie 

 writer's coat, were recognised as small Horaopterous insects, further specimens 

 of which were subsequently identified by the writer's colleague, Mr. F. Laing, 

 as imagines of Typlilocyba idmi L. — a Jassid bug which, in its larval stage, is 

 parasitic on the leaves of the elm. Somewhat curiously, when seen in the air on 

 the occasion mentioned, all the insects appeared to be moving against the wind, 

 apparently drifting from the direction of Kensington Gardens towards the 

 north-east, although a keen north-easterly current of air was making itself 

 unpleasantly felt at the time ; the possibility that a local eddy in the air- 

 current may have determined or influenced the direction of flight was, unfor- 

 tunately, not investigated. Since October Oth, only isolated specimens of 

 7'. ulmi have been noticed by the writer on the wing in Hyde Park, although 

 before 10 a.m. the resting insect has been observed in numbers on the trunks 

 of various species of trees near the Serpentine, and especially in the crevices 

 of the bark of the horse-chestnuts outside the railings of IMie Magazine. 

 According to Mr. Laing, T. ulmi hibernates iu the adult state, so that the 

 insect's activity at the present time may be stimulated by the necessity of 

 tiuding suitable winter-quarters. That houses sometimes do dui^^ for the latter 

 is not impossible ; at any rate, during the present week T. ulmi has been found 

 in nutnbers on a window in a house about 150 yards or less from the south- 

 western corner of Kensington Gardens. If any reader has observed Typhhcyba 

 ulmi swarming on the wing elsewhere than in London, perhaps he will be good 

 enough to place his observations on record. — E. E. Austen (Major), British 

 Museum (Natural History) : October I2th, 1022. 



A Synonymical Note on Orthezia inaenariensis Douyl. (Coccidae). — Douglas 

 in 1884 (Trans. Ent. Soc. Loud. p. 81) described Orthezia maenariensis from 

 the Island of Montecristo. According to his description the species was 

 peculiar in that the adult 2 ^''-d 9 segments to the antennae, and the 

 adult (5 possessed three ocelli on the head. Acting on the supposition that 

 the species possessed these characters (which, if true, would make them aber- 

 lant for the Ortheziinae), MacGillivray in "The Coccidae " (1921) erected 

 Douylariella (surely a misprint for Douglasiella) with maenai-toisis as type. 

 At the suggestion of Mr. Harold Morrison, U.S. Bureau of Entomology, I have 

 examined Douglas's types. These were still contained iu mica cells as Douglas 

 received them from Lichtenstein. As no details could be made out through 

 the mica, the specimens have been remounted on slides. The 2 instead of 

 iiaving 9-segmented antennae, as Douglas described, has one 7-seyuieuted and 

 the other 8, while the J has but the two normal, lateral ocelli. Lindinger 

 had already (" Die Schildlause," 1012) suggested that O. muenariensis was 

 synonymical with O. nrticae L., and, except for its slightly snuiller sii?e, I can
