little reliance can be placed in the neuration, so variable is it. But it 

 may be after all a distinct species, for it is stated by Zaddach (I. c.) 

 that Herr Brischke bad bred testaceipes as well as ventralis, a state- 

 ment that would lead one to conclude that the larvae of the two 

 differed. The larva of ventralis only is, however, described, and it 

 feeds, like stilata, on Pyrus aucuparia. The other variety of testaceipes 

 is a little larger ; it has the abdomen quite black, or with only a portion 

 of the anal segment testaceous ; and the antennae have the under- 

 surface only very faintly testaceous. This is, I presume, the true 

 testaceipes of Klug and Ilartig.

DiXEUEA SELANT)EIirOEMIS, Sp. 11. 



D. nigra, suh-nitida, ore, terjulis, pedibusq^ue alhidis ; pronoto fere 

 toto, ventre suhtus, anoque pallide rufescentihus ; femorihus anticis basi, 

 posticis fere totis, posticis tarsis et tibiarum dimidio apicali, nigris ; 

 alls hyalinis, stigmate fusco. Long, fere 1\ lin. 



$ . Autennse about the length of the head and thorax, black, modei-atelj thick, 

 the 3rd and 4th joints nearly equal. Head black, very slightly downy ; the clypeus 

 and labrum white. Thorax black, shining, slightly downy ; the pronotum almost 

 entirely reddish ; the tegulae white. The cenchri are scarcely distinguishable. Ab- 

 domen of the length of the head and thorax, black above, the sides, extreme apex 

 above, and ventral surface, dull reddish. Wings hyaline, costa and stigma fuscous, 

 the costa a little paler than the stigma ; the 1st sub-marginal nervure is very faint, 

 the 3rd sub-marginal cell is longer than broad, widest at the apex. The marginal 

 nervure is received a little in front of the middle of the 3rd sub-marginal ceU ; the 

 2nd recurrent a little in front of the 2nd sub-marginal. Legs testaceous ; anterior 

 femora at the base slightly, posterior entirely (except the knees), the apical half of 

 the posterior tibia;, and the posterior tarsi, black, the four anterior tarsi faintly fuscous. 



There is a variety of verna, having some resemblance to this 

 insect, but differing from it in the following points : the mar- 

 ginal, 2nd sub-marginal, and 2nd recurrent nervures are all joined 

 together ; it has the body much more downy, larger and stouter ; the 

 antennae are thicker, and apparently shorter in proportion ; and, 

 finally, the posterior tibiae and tarsi are white. 



One example has been taken at St. Albans by the Eev. T. A. 

 Marshall. 



D. parvula, Kl. — This is described by Stephens (111., vii, 52, 31), 

 but I have never seen a British specimen. It is placed by Thomson 

 in JSlennocampa, next to £. pusilla.
