NEMATUS TURGIDUS. 103 



with white antennas, wings, and legs. There are, I 

 believe, two broods in the year ; one in early summer 

 (June), the second in August. With regard to the red 

 variety of the larva) I may mention that they seem to 

 be very delicate and difficult to rear compared to the 

 common form. 



This is one of our commonest and most widely dis- 

 tributed species. It appears to be commoner in the 

 north than in the south. 



Continental distribution : Lapland, Finland, Sweden, 

 Russia to the Ural Mountains, Germany, Holland, 

 France. 



Obs. Great confusion has existed as to what species should be 

 regarded as caprea. Linne's caprece cannot be determined as the 

 imago was not described, but only the larva. The next description is 

 that by Panzer, whose caprece is identified with that here described by 

 his figure which is good enough. Fabricius apparently described a 

 different species, yet he quotes Panzer's figure. The caprece of the 

 other old systematic writers need not trouble us. Of the modern 

 authors Hartig's caprece is rumicis, Fall., while sundry willow-feeding 

 larvae have been described by various writers under the name of caprece. 

 After the figure of Panzer, the next certain name is that of Kir by i 

 applied to it by Dahlboni. The name of caprece is scarcely an appro- 

 priate one, yet as the oldest which can be fixed with certainty it must, 

 in accordance with the law of priority, be adopted. The caprece of 

 Fallen and Zetterstedt is fallax, Lep. In Stephens' collection, caprea, 

 Pz., is represented under the name of N. taniatus (in part), hamor- 

 rhoidalis, fallax, and affinis.

Antennae black, nearly as long as the thorax and abdomen, tapering 

 towards the apex, slightly pilose, the third joint shorter than the 

 fourth. Head narrower than the mesothorax, pale yellow, the 

 mouth paler, covered with pale down ; the frontal area distinct, the 

 front itself projecting; the antennal furrows proceed round the base of 

 the antennae ; clypeus a little emarginated in the middle, labruin pro- 

 jecting; the mandibles are black at the apex; the space surrounding 

 the antennae and around the ocelli black. Thorax smooth, shining, 

 with a few shallow punctures and faint scattered down ; pleurae and
