THE ENTOMOLOGIST. 223 



Description of the Larva of Eupithecia togata. — General 

 colour dull pinkish brown ; central dorsal, subdorsal, and 

 spiracular lines whitish, indistinct, especially the two latter ; 

 skin wrinkled ; body sparsely studded with black tubercles 

 and short hairs; head and collar glabrous and horny, dusky 

 brown. A queer internal-looking creature, strikingly like 

 a miniature Cossus Ligniperda. Feeds inside the buds and 

 young shoots of spruce-fir. I am indebted to the kindness of 

 Mr. Hellins, of Exeter, who reared it from the egg, for the 

 opportunity of seeing and describing this, I believe, hitherto 

 unknown larva. Mr. Buckler has succeeded in taking its 

 portrait. Hatched, July 18th. Full fed the end of August.

Mosquitoes. — In England there are three genera of Diptera 

 Nemocera, or thread-horned two- wingers, that sting and draw 

 blood with their mouths; and there is no recent instance of 

 any foreign kind having migrated to this country. These 

 genera are — Culex, or gnat ; Simulium, or sand-fly ; Cerato- 

 pogon, or midge. In Lapland, in America, and in other 

 countries, the gnat is called the mosquito ; and the attacks 

 of the Lapland gnat are not ie^v and feeble, as are those of 

 the English gnat. In Italy the mosquito is not a gnat: its 

 name is Phlebotomus Papatasii ; its hum is more soft and 

 low than that of the gnat; the genus to which it belongs is 

 not found in England ; the family in which it is included is 

 represented here by Psychoda, the little moth-like fly that 

 may often be seen on windows. — Fra/icis Walker. 



Orgyla Gonostigma and Papilio MacJuton at Malclon. — 

 About a fortnight ago my brother and myself captured a male 

 specimen of O. Gonostigma, flying briskly in the sun, close 

 to Maldon. I cannot hear of the previous occurrence of this 

 insect in these parts. Another insect, new to this district, 

 was captured at Maldon about the same time. A specimen 

 of P. Machaon was impaled on a needle by Mr. Gutteridge, 

 whilst sitting on his garden wall in the middle of the town. 

 It does not seem possible that the insect could be a bred one 

 escaped, as there is but one entomologist in the town, who 

 does not plead guilty to having had any Machaon pupae this 

 year. The marshy nature of the surrounding district renders 

 it not improbable that Machaon may breed regularly in some
