appearing in May; I have found it in numbers at Chobham on Saro- 

 thamnus scopariu><, accompanied by its inquiline Noinada sexfasciata. 

 The lon<^ antennse of the males can be seen easily when the insects fly. 

 There are two species of Anthophora which appear in the summer, 

 furcata and quadrimaculata, the former is not a common insect, but is 

 widely distributed over the southern half of England ; the latter is 

 very local, but not uncommon where it occurs ; both have a very high 

 pitched note when flying, and visit labiate plants, such as Lamiwn 

 purpureum, &c. ; furcata makes it cells in decayed wood, quadrimaculata 

 in banks, &c. Saropoda himaculata has also a very shrill hum, and is 

 a most active little bee, darting from flower to flower with great 

 rapidity ; the eyes of the male are particularly beautiful, being of a 

 pale greenish tinge with darker spots, which seem to show through 

 from a deeper level ; it is abundant in many localities, especially in 

 sandy places, such as Chobham, &c. It is scarcely distinguishable 

 generically from Antlwphora, and Friese, in his Monograph of that 

 genus (which he calls Podalirius), includes Saropoda therein. In 

 July and August the males of most of the species of Bomhus and 

 Psithyrus aj)pear, as also those of Halictus and Sphecodes, in fact 

 August or early September is the best time for collecting the species 

 of these genera, as the sexes may then be found together, whereas in 

 the early part of the year only the hibernated females appear, also 

 the specimens are in their best condition at this time of year, having 

 only recently emerged. The female Halicti are not now to be found so 

 frequently at flowers, but are seen round their burrows ; the males, 

 on the other hand, often swarm on thistle heads, &c., especially those 

 of cylind7'icus and aJhipes ; the great similarity of the s])ecies makes 

 them very difllcult to study, and still more difBcult to recognise in the 

 field. There are two very rare species of Bomhus to be looked for in 

 this country , pomorum and Cullumanus, the former has only occurred 

 at Deal, the latter at Southend ; pomorum is coloured somewhat like 

 Japidarius, but the abdomen is clothed with hairs which gradually 

 shade from black at the base into browiiish-red at the apex, whereas 

 in Inpidarius the division between the black and red is clearly defined. 

 Cullumanus re^QvabXes pratorum, but the posterior metatarsi are fringed 

 with much shorter hairs, and the face of the ? is broader and squai'er. 

 Neither of these rarities has been recorded for many years as having 

 been found in this country. Bombi and Halicti may sometimes be 

 found as late as the end of October ; 1 remember well taking a consider- 

 able number of species of both genera on the East Cliff, Hastings, on 

 the 20th of that month, but then the weather was unusually warm and
