224 NOTES. 



Hal). White Mts., N. H. (E. P. Austin; his labels were mtukcd: 

 ,,woods" and ,, alpine''). Three females, only one of which is well pre- 

 served; the other is greazy; the third teneral, and for this reason ol a 

 uniformly reddish color. 



This remarkable insect looks like a Leptid with the antennae of 

 Cofiio)>ii/ia. I refer it to the genus Artltroptas Loew, Stett. Zcit. 1850, 

 with which it seems to agree in the generic characters. It differs from 

 the figures given by Dr. Loew, in having the anal cell open, the discal 

 narrower, the posterior cells 2, 3, 4 longer. The second posterior cell 

 is very narrow at base and the upper branch of the third vein is not 

 Insinuate. I cannot at present compare this species to A. anirr/i-in.d, 

 and cannot therefore tell whether the structure of the face is the same 

 in both. In A. Icptis two deep, diverging furrows, run from the base 

 of the antennae to the oral edge, and divide the face in three portions. 

 Besides A. sibirica, diuericat/n and hptis, a species of the same genus, 

 A. turn a , occurs in amber. The doubts of Dr. Loew about the syste- 

 matic position of Artlirvpcas are revealed in the fact, that he refers it 

 to the Coenomyidae in the Stett. Zeit. and to the Acanthomeridae in 

 the pamphlet: Der Bernstein und die Bernsteinfauua , although both 

 papers appeared in the same year 1850. 



The genus Coemira Bigot, from Chili (Ann. Soc. Entomol. de 

 France, 1857) is most closely allied to Arthrojictt* and has even, in the 

 coloring of the species described a certain family resemblance to A. 

 silnrica. In fact it remains to be shown yet, in what the difference 

 between the two genera consists.

50. Exaireta Schiner. There exist the following, similar names: 

 Exaerete, Hymenopt. 1848; Exaeretus, Hemipt. 1864; Exaeveta, Coleop- 

 tera 1865. About the relation of Exairda to Uipltysa Macq. compare 

 Nowicky, Beitrag zur Kenntniss der Dipterenfauna Neuzeelands, Krakuu, 

 1875, p. 12. 



51. About Sargus and the allied genera, see Loew's essay in Verb. 

 Zool. Bot Verein 1855. A great deal remains to be done as yet for 

 the classification of the exotic species of Sarguia. I did not attempt 

 to refer the species which I have not seen to the newly-formed genera 

 to which they may belong, but left them in the genus Sargus in the 

 old acceptation. 



52. As there is an earlier Chrysomyia R. Desvoidy, 1^30, I revived 

 the name of Clrturomyia Duncan, in my Western Diptera, p. 212. 

 Macquart himself acknowledged the priority of Chrysomyia Desvoidy 

 in Ann. Soc. Ent. 1847, p. 75. 



53. Ptecticus. In Mr. Loew's paper on Snrgus, where this genus 

 is introduced, it is always called Ptecticus; on the plate, it is calle I 

 Plectiscus, and Gerstaecker (Entom Ber. 1855, p. 127) adopts the latkr 

 version. Mr. Loew told me that Ptecticus was the correct form.
