entirely clotlied with black hair except tlic scutellum and tip o£ the 

 abdomen, which are covered with yellow or whitish-yellow hair. The 

 posterior femora in this species are greatly swollen. All our British 

 CriorrhincB are handsome insects. 



Pocota apiformis, Schrk. — In the arrangement and colour of the 

 yellow and black hair this closely I'esembles Criorrhina herherina, P., 

 but is easily distinguished by its small head and by a conspicuous dark 

 brown band which extends half way across the middle of the wing. 

 Of this and the preceding species a series was taken last year in the 

 New Forest. This and several of the insects mentioned above are 

 exceedingly like Bombi (humble bees). 



Spilomyia speciosa, Rossi. — Of this beautiful exotic-looking fly 

 there are three specimens. One from Brockenhurst, the other two 

 from Mr. Clifton's collection. Several specimens of this species were 

 taken in the New Forest in 1893. 



Callicera cBnea, F. — This is also a very fine insect, and is remark- 

 able among British SyjpliidcB for having the antennae like those of a 

 Conops. There is one specimen in the collection from the neighbour- 

 hood of Derby, presented by the late Mr. W. C. Hewitson. I believe 

 only four other specimens have been recorded as taken in Britain, 

 three of them in 1888. Ent. Mo. Mag., 1889, pp. 186 and 238. 



Other species of Syrphidce worthy of notice are Psilotaatra, Flu., 

 1 (^ and 2 ? from Lyndhurst, Brachyopa hicolor, Fin., four specimens 

 from Lyndhurst and Christchurch, and Brachypalpus himaculatus, 

 Macq., 4(^ from the New Forest. 



Of other families of Diptera I propose only to give details of a 

 very few species. 



Nephroceo'us Jlavicornis, Zett. — This is one of the Pipunculidae, 

 but larger than any other British species. The venation is very like 

 that of the genus Pipunculus, but the fourth longitudinal vein is 

 forked. 



This insect and Mallota eristaloides were taken by Mr. F. C. 

 Adams in the New Forest last year and recorded as British in Ent. 

 Mo. Mag., Nov. 1891, p. 255. 



Among the Conopidce there are several interesting species. I will 

 mention two of them. 



Conops vesicularis, Mg. — Of this species, the largest of the 

 British Conopidce, there is a nice series of both sexes from the New 

 Forest. It is generally considered a rare species. O. ceriiformis, Mg. — 

 This species is remarkable for the very great difference between the 

 sexes ; the female being slender and dark, the male much like the 

 light variety of C. quadrifasciata, with the abdomen egg-yellow.
