Aphiochaeta. 319 



there is an old specimen in Stæger's collection, determined as piili- 

 caria and labelled "Zett. det.". 



Geographical distribution: — Denmark, England and down into 

 Germany (Becker). 



Remarks: The present species is evidently the sordida of Wood 

 and no doubt also of Becker, as seen from his figure of the hind femora 

 of the male and as he gives the palpi as yellow, but it is not sordida 

 Zett., I have therefore chosen the new name Woodi for it. I have 

 examined Zetterstedt's types of sordida; in the collection to Ins. 

 Lapp. there is a male labelled "Lycksele" and a female labelled 

 "Karesuando", and in the collection to Dipt. Scand. there is a pair 

 on one pin labelled "Karesuando"; the study of these types proved 

 that it is another species than the present, though related to it, and 

 they proved to be identical with the newly described A. scaura Schmitz 

 (Entom. Ber. Nederl. Ent. Ver. V, 1921, 322, 4), which I was able to 

 decide with certainty, as I possess a type of scaura^ kindly given to 

 me by Pater Schmitz; this species is thus the real sordida Zett. Becker, 

 who had seen Zetterstedt's types, must have made a mistake, which 

 is easily understood, as the species are rather related; it is also seen 

 that he describes the palpi as yellow, while Zetterstedt describes them 

 as black or, in the female, as "lividi". The fringe below the hind femora 

 in the male is very different in the two species. Trineura carbonaria 

 Zett. Becker declares to be a variety of ruficornis, but a study of the 

 type (there is only the one male specimen mentioned by Zetter- 

 stedt) shoved that it is identical with sordida Zett. Finally I shall 

 remark that besides the mentioned types of sordida there was still 

 a male in the collection to Dipt. Scand. labelled "Lycksele" which 

 is not this species, but which seemed to me to be fiiscipalpis Lundbk. 



Phora Heracleellae Bouché (1834. Naturges. d. Ins. I, 102, 95 and 

 Schin. 1864 F. A. II, 34), which Becker considers the same as his 

 sordida, is no doubt more probably A. rufipes; Bouché seems to have 

 confused the sexes, and Schiner has perhaps done the same.
