months of January and February I collected any perforated slicks that looked 

 promising, and placed them indoors in large glass bottles with leno covers in a good 

 light. Several good species emerged from these in due course, as noted below. 

 March was very fine and warm, and most of the early species of Andrena were to 

 be seen, such as clarkella, Kirb., gwynana, Kirb., nigroxnea, Kirb., &c. On 

 April 1st two Osmia pilicornis, Sin., $ and f? , were taken on the Guildford Downs, 

 together with H allot us laeoigatus, Kirb., villosulus, Kirb., eglindricus, Fab., and 

 Podalirius pilipes, Fab. Later on Andrena spinigera, Sm., a light brown variety f 

 tibialis, Kirb., bimaculata, Kirb., nitida, Fourc. , thoracica, Fab., fuloicrus, Kirb., 

 and dorsata, Kirb., occurred at Cobham. In May I took the rare Andrena 

 bucephala, Steph., at Box Hill, also spinigera, Sm. (worn), and helvola, L. ; in my 

 garden at Cobham Andrena angustior, Kirb., ambigua, Ferk.,Jlorea, Fab., humilis, 

 Imh., wilkella, Kirb., Crabro vagabundus, Panz., Odynerus trifasciatus, Oliv., and 

 Nomada ochrostoma, Kirb. Andrena lapponica, Zett., was seen at its old locality 

 at Horsley. On May 21th I received from my friend, Mr. C. Reuss, three fine 

 males of the very scarce Andrena ferox, Sm., which had fallen into his tray whilst 

 beating for larva; in the New Forest. A short visit to Criccieth aud Abersocli in 

 early June for Osmia parietina, Curt., and xanthomelana, Kirb., was successful, 

 though the insects were scarce. The females of Eombus soroensis, Fab., were 

 abundant at Abersocli on the flowers of the currant. On my return home I found 

 that a number of Osmia leucomelana, Kirb., had emerged from one of the perforated 

 bramble stems, together with Stelis 8-maculata, Sm., one $ and two $ ? . On 

 cutting this stem open I found the first two cells were Osmia, the third Stelis, the 

 fourth Osmia, the fifth Stelis, the sixth and seventh Osmia, the eighth Stelis, the 

 ninth Osmia, and the tenth an imprisoned Pemphredon, dead but fully developed. 

 In another stem, containing leucomelana cells, I was astonished to find in the two 

 bottom cells a dead Stelis 8-maculata, Sm., and a male leucomelana, head down- 

 wards, both fully developed. This is very remarkable, as the bottom cells usually 

 contain females. A day at Oxshott produced Sapyga ^-punctata, Fab., c? $ > 

 Pompilus cinctellus, Spin., Salius parculus, Dhlb., Psen shuckardi, Wesm., the 

 uncommon Pemphredon wesmaeli, Mor., Caelioxys quadridentata, Linn., elongata, 

 Lep., and Osmia ccerutescens, Linn. Towards the end of the month Mr. Q. C. 

 Vaux sent me five Psenulus concolor, Dhlb., bred from perforated ash-stems taken 

 at Ockley, the first of this rarity bred in England ; also Crabro capitosus, Shiick., $ , 

 from the same locality. My captures for July include among others, Agenia hircana, 

 Fab., Nysson trimaculatus, Rossi (on bramble leaves), and Psen shuckardi, Wesm., 

 equestris, Fab., bicolor, Jur. (Daucus carota flowers), Crabro palmarius, Schreb., 

 vagus, Linn., panzeri, v. d. Lind , Andrena rosx, Panz., bimaculata, Kirb., nigriceps, 

 Kirb., denticulata, Kirb., argentata, Sm., and dorsata, Kirb. (second brood) ; 

 Nomada solidagiuis, Panz., lineola, Panz. (second brood), jacobaza;, Panz., albo- 

 gutlata, H.-S., and Stelis phceoptera, Kirb. Towards the end of the month the 

 very scarce Goryfes bicinctus, Rossi, and lleriades truncorum, Linn., appeared in 

 the garden. (For my note on the latter see Ent. Mo. Mag., xliii, p. 276). 



Most of the above insects occurred also during the first weeks in August, with 

 Pompilus minutulus, Dhlb., chalybeatus, Schiodte, Stiamus solskyi, Mor., Pem- 

 phredon morio, v. d. Lind., Nysson dimidlatus, Jur., Cerceris rybyensis, Linn.,
