?, when plllpcs appareutly was over. Lucliiosa lias been talit'U by 

 Mr. Saunders at Chobbam, but 1 bave uever succeeded in finding it 

 myself anywhere in this neighbourhood. Whenever 1 have looked 

 for it in retusa colonies I have only found armata. 



At Swanage this spi-ing I saw a few specimens of luctuosn which 

 were certainly associating with reiuna; but even there ^rwr/ffl occurred 

 also, and in much greater abundance. 



M. luctuosa is a common species on the Continent, but in England 

 it seems to be decidedly rare, even in localities ^\here retusa is plenti- 

 ful. I know of no district in which pili2)eii and armaia are not to be 

 found nd libitum. 



3. Eucera longicornis, L. — It is perhaps worth noticing that our 

 species - or, at least, all specimens that I have taken or seen of it — 

 has a coarsely or rugosely punctured mesonotum, and is, therefore, 

 not the species considered abroad {cf. Friese, A p. Europ.) to be the 

 true '' loiifjicornis'' of L. Our species is that described by Friese 

 as " difficilis, Perez." Unluckily there is nothing whatever in the 

 Linnean description to show which of the two species he had before 

 him. 1 have taken both in the Alps. A priori one would rather 

 expect that our species, which is also, as Herr Alfken has told me, 

 the only form he takes in North Germany (near Bremen) would be 

 that familiar to Linne. But I am not prepared to argue the question, 

 and would merely point out that our lon(jicornis'\% not that of "Apidse 

 Europsere, Friese." 



4. Ellampus cwmdeus, Dhb. (?). — 1 took on June 27th last, in a lane 

 near Chobham, a very queer little Chrysid, which, I think, must be a 

 variety of this species— probably an exceedingly dark specimen of the 

 variety virens, Mocs. Its colour is almost entirely inky-black, with 

 metallic green tints only on the sides of the abdomen and the legs. 

 uEneus, Pz., which is not rare near Chobham, sometimes goes quite 

 black, and I should refer my insect to that species, but that there are 

 distinct punctures at the base of the mesonotum. These punctures, 

 it is true, are hardly so strong as in normal specimens of cceruleus ; 

 still, they exist, and there is no trace of anything like them in any of 

 my specimens of ceneus. 



E. ccdruleus var. virens has occurred in England. I have a speci- 

 men found by Mr. Watkins in an old cherr^^ tree. 



5 Odj/nerus Icevipes, Shuck. — Some years ago I picked up a dried 

 bramble stem from a heap beside the road from AV^oking to Guildford, 

 from which next summer I reared a (J and a ? of this apparently 

 rare species. Happening last winter to pass the same spot I again
