THE ENTOMOLOGIST. 239 



1 . Sjntomis Phegea of Linneus, which occurs in the South 

 of Europe, irii a few districts of Germany, In Silesia, Belgium 

 and Pomerania : it is a gregarious species, the larvae feeding 

 in company on many low plants, and also on Prunus Padus 

 (the bird-cherry). 



2. Naclia Ancilla of Linneus, which inhabits Southern 

 Europe generally, and extends northwards as far as Silesia. 



3. Naclia punctata of Fabricius, which is found in the 

 South of France and on the Ural mountains, in June and 

 July. 



4. Naclia hyalina of Frivaldsky, which occurs in Turkey. 

 A geographical race of this species, inhabiting Dalmatia, so 

 closely resembles N. Ancilla as scarcely to be distinguished; 

 but Herrich-Schaeffer's figures of N. hyalina (Suppl. Bomby- 

 cidae, fig. 127) appear abundantly distinct from that species. 



The genus Naclia of Boisduval is closely allied to Synto- 

 mis, but is separated by some slight differences in the num- 

 ber and disposition of the wing-rays. 



Naclia Ancilla, the second species in the preceding list, 

 has the fore wings ochraceous-brown and semihyaline, with 

 three nearly circular white spots on each : two of these are 

 closely approximate, placed transversely, and equidistant 

 from the costa and anal angle, but slightly nearer the hind 

 margin ; the third is much smaller, and is equidistant be- 

 tween the upper of the two spots already described and the 

 costa ; the hind wings are unspotted, and slightly darker 

 than the fore wings ; the antennae are strictly setaceous and 

 of a dark brown colour ; the eyes prominent and intensely- 

 black ; the crown of the head, collar, shoulders and abdomen 

 rich ochreous-yellow ; the last has a medio-dorsal series of 

 six black spots. Expansion of the wings one inch. In 

 general facies and habit it closely resembles a Lithosia. 



Larva obese, hairy, closely resembling those of the Litho- 

 siae, feeding on lichens and spinning up in the same manner. 



Mr. Wildman possesses the only British specimen yet 

 obtained ; he took it near the sea-coast of Sussex, and has 

 kindly placed it in my hands for examination : Mr. Double- 

 day has since verified the name.
