no ciliutiou boneath the hind femora, the tip of the inidtUe tibiaj is generiillj infus- 

 cated, and then the middle tarsi are scarcely pale at the base, the apical eighth of 

 the hind tibi.'E is blackish ; the basal joint of the hind tarsi bears two large bristles 

 above. Cilia of alulee all black. Wings distinctly brownish on the anterior portion, 

 especially about the veins, but with no trace of a stigmatical swelling, the discoidal 

 vein ending distinctly before the tip of the wing. The female has the face broader 

 and rather paler, the body (especially the abdomen) more coppei-y, the antennae 

 shorter, the third joint being nearly round, and the legs more lutcous. 



There is a small group of closely allied DoUchopi possessing the 

 following characters iu common : femora and cilia of the lower orbit 

 pale, antennie black, with the base pale beneath, legs simple without 

 even the hind femora ciliated beneath, or the middle tarsi silvery at 

 the tips in the males, the antennae not inordinately long, the discoidal 

 vein simple and the wings unsj)otted, without any stigmatical swelling 

 in the male. The species hitherto described in this group are puncti- 

 cornis and lineaticornis, Zett. (1843), grandicornis and caJigntus, 

 Wahlberg (1850), and consohrinus, Zett. (1850). The only species of 

 these five recorded out of Scandinavia are lineatieornis, which is given 

 as British in Walker's " Insecta Britannica," and noted as common in 

 Germany by Loew in 1857, and puncticornis, noted by Loew from the 

 Alps. The most distinct of these five seems to be puncficornis, with 

 its " epistoma ochraceum " and "antennae articulo basali subtus ad 

 " apicem puncto parvo luteo a?gre observaudo," — characters which im- 

 mediately separate it from mediicornis : lineatieornis seems to be dis- 

 tinguished from the latter by "epistomate flavido — nervo long, -ito 

 '* leviter flexo fere iu apice alae excurrente — similis priori (Jrivialis, 

 "Hal.) sed epistomate flavescente, antennis paullo brevioribus, articulo 

 " ultimo ovali, parum acuto (nee elongato, acuto) — et magnitudine 

 " iionuihil majori abunde distinctus." Tf mrditconiis be compared 

 with friridlis, it is slightly smaller, the epistoma is of almost the same 

 hue, or even whiter, and the antenna? are distinctly longer, especially 

 the third joint. The lincntinornis of the Insecta Britannica is also de- 

 scribed as "face ochre-yellow in male, dull whitish in female," and is 

 therefore in all probability distinct from mediicornis. Grandicornis 

 has " epistomate aureo-ochraceo — antennis articulis basalibus subtus 

 " f ulvis, coxis posterioribuB basi ad ^ cinereis, tibiis posticis ad sextam 

 " partem iiidctcrmiiiate dilute infuscatis," and therefore seems distinct. 

 Caligatus has "antennis capite transverso brevioribus, articulis basali- 

 " bus subtus anguslissime fulvis, coxis posterioribus basi ad I cinereis, 

 "nervo ([uarto in ipsum fere apicem ala) excurrente. Mas; stigmatc
