What confidence may be placed in Walckenaer's quotations, is 

 shown, among other things, by the manner in which he has treated 

 C. Koch's Calliethera-s^edes. He cites C. zebranea not only together 

 with C. scenica under his Attus scenicus, but also under his Attus 

 erraticus (A. tigrinus Westb.). He adduces G. histrionica under A. 

 psyllus {A. terebratus Westr.), and identifies C. tenera with Salt. 

 Umbatns Hahn! ') It would scarcely be worth while to mention all 

 the unreasonable mistakes , which this writer has committed in citing 

 C. Koch's Attoidae, were it not that many persons have been led into 

 error by them. — 



In E. scenicum the patellar joint of the palpus, viewed from 

 above, is at least double as long as it is broad; the process at the 

 apex of the outside of the tibial joint is pointed and much bent in- 

 wards; the extremity of the lamina is short and bent abruptly down- 

 wards, the bulbus is narrow and irregularly egg-shaped, somewhat 

 pointed in front; towards the apex it is depressed or (when viewed 

 from the side) slightly and regularly excavated. The vulva consists 

 of a large, rounded, pretty deep, dark fovea, which in the anterior 

 part of the bottom exhibits two shallow depressions; behind, where 

 the fovea gradually becomes shallower, it is drawn out into a short 

 point, divided by a short furrow into two dark tubercles or teeth. 



In the male of E. cingulatum, the patellar joint of the palpus 

 is nearly double as long as it is broad, the process of the tibial 

 joint is directed forwards and outwards, almost straight, scarcely 

 perceptibly curved inwards; its lower edge is almost straight, not 

 dilated into an angle; the bulbus is behind the apex divided by a 

 very deep depression into two parts, the posterior large, egg-shaped 

 and strongly arched, the anterior thin , narrow and lying immediately 

 under the anterior extremity of the lamina; the truncated and 

 deflected apex of the lamina reaches far in front of the posterior 

 convex division of the bulbus. 



E. cingulatum is somewhat smaller than E scenicum (the cepha- 

 lothorax usually 2 — 2'/ 4 millim. long); the body narrower and longer. 



l) Walck., H. N. d. Ins. Apt., IV, p. 408—410. — Hahn has not, as is stated 

 by Simon in his Monogr. d. Attides , p. 575 (109), given "a very imperfect de- 

 scription" of S. Umbatus Hahn, but only a figure, without any description at all. 

 Walckenaer, on the other hand, has manufactured a description of the species 

 (Ins. Apt., I, p. 408) from Hahn's figure. S. Umbatus Hahn is probably no- 

 thing more than a variety of Attus falcatus (Clerck), Westr. : see that species 

 farther on.
