BRTOOAMPA OVATA. 171 



specimen from Chertsey (Billups) has the femora of a 

 much clearer reddish tint and without black, the white 

 at the base of the tibise not so great, and the three 

 apical segments have no white or luteous marks. The 

 antennge are shorter a little than the abdomen, thickish, 

 the third and fourth joints subequal; abdomen with 

 the segments largely marked with white on either 

 side, the last segment with a triangular (A-shaped) 

 depression; the femora and tibiae reddish-yellow; the 

 tibise fuscous, the joints white at the base. 



PCECILOSOMA GUTTATUM (Yol. I, p. 215). 



Konow (D. E. Z., xxviii, p. 32) describes this species 

 under the name of carbonaria, Knw., and 1. c, 1890, 

 he gives guttatum, Thorns., as a synonym. 



Guttatum, Fall., non Thorns., he refers to impressum, 

 Kl., and submuticum, Thorns. There can be no doubt 

 that the latter two are identical, but it also appears 

 to me that impressum (as Klug himself suggests, 

 Berl. Mag., viii, 113) is identical in all probability with 

 carbonaria, Scop., Ent. Cam., 279, 733. This is also 

 the opinion of Eogenhofer and von Dalla Torre (Yehr. 

 z.-b. ges. Wien, 1881, 596), who say that the descrip- 

 tion and the fairly good figure agree with impressum. 



As Fallin had mixed up two species under the name 

 of guttatum, Thomson had the choice of applying the 

 name to either of them, and I propose to retain his 

 name, and for submuticum that of carbonarium, Scop. 



Eriooampa ovata (Yol. I, p. 221). 



Konow (D. E. Z., 1890, 250) reserves the name of 

 Eriocampaiov ovata, L., umbratica, Kl., and dorpatica, 

 Knw. 



For the other species he creates the genus —
