OF EXTBi^-EUBOPEAN TBIOHOPTEBA. 139 



zable by tlio broad triangular superior median lobe, which is 

 carinated above. As a rule, the species of the genus, which are 

 probably as numerous in North America as in Europe, can only 

 be separated by the abdominal characters. T. (?) livida, Hagen 

 (N. Araer. Neurop, p. 295), is unknown to me. I once saw the 

 type of T. (?) hirtipes, Curtis, and noted that it was an Apa- 

 tania, a genus belonging to another family. 



Pam. EIIYACOPIIILIDiE. 



Agapetus, Curtis. 



Agapetus CELATUS, n. sp. ^.fuscus. Caput thoraxqueflavo-hirsuti. 

 Pedes fusci, feraorura apicibus luteis ; tibiis posterioribus griseo-fim- 

 briatis (tibiis tarsisque intermediis $ valde dilatatis). Abdomen fu- 

 scum, scgmento antepenultimo ventrali <J $ unidentato. AIje anticre 

 nigricantes, brunneo-pilosoe, nigro-brunneo-fimbriata; : posticse nigro- 

 fuliginosse, micantes, griseo-fimbriatse ( c5' $ ). 



Long. Corp. If lin, (=3^ mill.); exp. alar. 6| lin. (=12 mill.).

Blackish-fuscous. Head and prothorasc clothed with golden or yellow 

 hairs ; ocelli whitish yellow ; palpi and antennae blackish-fuscous. 

 Legs fuscous, trochanters and tips of the femora yellowish ; in the 

 S the posterior tibise are fringed with long grey hairs ; in the $ the 

 intermediate tibise and first tarsal joint are strongly dilated, concave 

 internally, and fringed with grey hairs. Abdomen fuscous ; in the 

 middle of the antepenultimate ventral segment in the c? is an ob- 

 tusely triangular short tooth, not extending beyond the margin of the 

 segment, and a somewhat similar, but shorter and broader, tooth is 

 also seen in the $ ; there is no tooth or tuft of hairs on the penulti- 

 mate segment : in thee? the app. inf. are elongately triangular, curved 

 inwards at the tips, rather widely separated when viewed from beneath, 

 fringed with yellow hairs externally; when viewed from beneath 

 there is an appearance of two small points projecting from the inner 

 side of the app. inf. close to their tips; these are probably the apices 

 of the penis-sheaths, and not connected with the app. inf. ; the penis- 

 cover seems to consist of one large piece placed above the app. inf. 

 and nearly reaching their tips (these anal parts are so strongly applied 

 one against the other in the dry example, that it is impossible to de- 

 scribe them with certainty) ; in the 5 the abdomen ends in a slender 

 ovipositor, which is curved downwards. 



Anterior wings uniformly blackish, somewhat shining, with a moderately 

 dense clothing of short brownish pubescence and long blackish fringes ; 

 veins blackish. Posterior wings blackish, subhyaline, and with
