Head somewhat constricted behind the eyes, black with the mandibles 

 mainly and palpi flavidous. Antennae subfiliform, with the scrobes dis- 

 tinct and scape rarely red. Thorax stout, finely punctate, very dull and 

 as broad as the head; notauli distinct; metathorax with five distinct areae, 

 of which the areola is longer than broad and pentagonal. Abdomen with 

 the basally aciculate second and the third segment usually apically brick- 

 red, sometimes all the segments are apically pale ; ventral plica flavidous ; 

 terebra nearly as long as abdomen. Legs red with coxae and usually 

 trochanteral base, sometimes also the hind femora, black ; hind tibiae 

 at least apically infuscate ; hind femoral tooth large and acuminate. 

 Wings slightly infumate, broad and apically obtuse with stigma ])iceous, 

 tegulae flavidous to piceous and the recurrent nervures far apart. Length, 

 6-8 mm. 



The only species with black thorax and facial orbits. 

 It is said to occur throughout Europe, to be somewhat common in 

 Belgium but scarce in Thuringia ; I\L'irshall has given it me from Nantua, 

 and Chapman a male bred from Litjjia paiicillmana and females from 

 Acrobasis porphyrella both at Cannes early in I\Iay, iqoi. In Prussia 

 Brischke raised it "aus INIaden von Coowsia in Plen's und aus Raupen von 

 Carpocapsa pomotmna, Rctinia Biioliana und Toririx Btri:;mantiuvia .... 

 Cocon cylindrisch, diinnhiiiitig, weiss, ausscn glanzend " (Schr, Nat. Gcs. 

 Danz. i88o, p. 197); Gaulle adds the dipterous ^l;////^wj7rz albimana and 

 Hartig also had raised it from Toririx Buoliona (Jahresb. 2(37). This 

 species should certainly be cultivated as one of the most beneficial to 

 apple-trees, for on 17th and 22nd of July, 1908, I took a nice series, 

 comprising both sexes, on the window in Monks .Soham House, Su(ToIk,of 

 a lumber-room in which apples had been stored during the winter; the.se 

 had almost certainly emerged from C. pomouana, since this moth also was 

 very common on the same windows along with it, though the first appear- 

 ed on the 13th inst. (r/. Zoologist, 1909, p.213). Curtis records it in 

 Farm Insects from Deprasaria daiicdla " and other kindred species ; both 

 sexes fre(iuent the parsnip when in flower, in the beginning of July, and 

 have been taken in the market gardens round London." Nevertheless, it
