1869.] 277 
On the 1st of March I received from Mr. Nicholas Cooke, of Liscard, near 
Birkenhead, a pair of bees, which he informed he could not find described in my 
book on the Bees of Great Britain, and as this opinion was verified by his brother, 
Mr. Benjamin Cooke, he felt satisfied they were likely to prove new. The beea 
were forwarded to me, and I at once recognized them as an unrecorded British 
species of the genus Colletes ; the Apis ctmicularia of Linne, and the C. hirta of 
most continental authors : it is a fine addition to our fauna, being the largest spe- 
cies found in Europe. 
Without an account of its capture, it would appear strange that so conspicuous 
an insect should not have been previously discovered. Mr. Cooke informs me that 
in 1867, his son Isaac (accompanied by his friend Mr. Samuel Holdsworth, Jun., a 
Lepidopterist,) was on an entomological excursion at the Underclifi", Isle of Wight, 
and that between Ventnor and Niton, in the month of May, his son captured four 
males and five females ; this is an early period of the season, when entomologists 
rarely visit distant localities — I allude to those who make annual excursions for 
fresh air and exercise ; this is usually done about the end of summer or during the 
autumn. This fact will, in some degree, account for the Colletes having remained 
previously imdiscovered. All the species of the genus delight in forming colonies 
in sandy banks, or olio's ; therefore, the chance of others finding the new bee is 
rendered more probable than if it belonged to a group of the more solitary species 
of the family. I hope myself to have at least the pleasure of searching for ib 
during the coming season. — Frederick Smith, British Museum, March, 1869. 
Two additions to the British Trichojptera. — I have recently received the two 
species noticed below. 
1. Halesus auricollis, 'Victet (Phry. auricollis, Pict., Eecherch., p. 141, t. 8, fig. 1 ; 
Hal. nigricornis, Brauer, Neurop. Aust., p. 47, nee. Pictet), belonging to the true 
genus Halesus, as restricted by me {i.e. posterior vrings of S without a pouch). A 
moderately large dark insect, with shining smoky-grey anterior wings, with darker 
pterostigma, and with a large and conspicuous white spot at the thyridium, and 
indistinct paler irrorations. Taken in some numbers at Kannoch, Perthshire, by 
Dr. Buchanan White, to whose kindness I am indebted for a fine series. A detailed 
description is postponed for my proposed first supplement to the "Trichoptera 
Britannica." I have carefully compared it with Pictet's type in the British Museum, 
and with Braner's types in my own collection, and consider it to agree sufficiently 
well, though there are some very slight discrepancies. The suspicion expressed by 
me in the " Annual '' for 1868, p. 4, that my guttatipennis might be identical with 
Pictet's species, is unfounded. That species is thoroughly distinct, and my exponent 
of it still unique as British, though I have since seen Swiss examples. 
2. Tinodes Schmidtii, Kolenati, {Potamaria Schmidtii, Kol., Gen. et spec. Trichop., 
pt. 1, p. 100, pt. 2, p. 229 ; Diplectrona Schmidtii, Brauer, Nem-op. Aust., p. 38). 
A small insect belonging to the group of T. pusilla, difi'ering totally from our re- 
coi'ded species by its dark coloration ; tho wings being smoky -black with a more or 
less distinct half-moon-shaped golden spot in the apical half, formed by hairs of 
that colour. Notwithstanding its diversity in colour from most other species of the 
genus, it is a true Tinodes, as the appendices alone would prove, these being all
