PSYCHE. 



[October — September iS 



domyidae^ for instance, are much more 

 important than the differences pre- 

 sented by the iinagines ; nevertheless, 

 one will not split \\\& cecidornyidae into 

 corresponding families for that reason. 

 Following is the description of the 

 new Hilarimorpha^ whose specific 

 name it gives me pleasure to choose 

 in honor of Professor Mik. 



Hilarimorpha niikii.^ ii. sp. 



^ Length 4 mm. Eyes broadly 

 contiguous. Face opaque gray, with 

 grooves from the oral margin. Anten- 

 nae brownish yellow ; the first two 

 joints short, the third oval, a little 

 longer than broad, the anterior bor- 

 ders straight or gently concave to the 

 insertion of the slender two-jointed 

 style, which is nearly as long as the 

 body of the joint. Thorax in ground- 

 color black, thickly covered on the 

 mesonotum with opaque yellowish 

 pollen ; on the pleurae with lighter, 

 less dense pollen. Abdomen with each 

 segment anteriorly brownish black ; 

 posteriorly broadly banded with opaque 

 yellow, of a color somewhat lighter 

 than that of the mesonotum. Legs 

 yellow, the terminal joints of the tarsi 

 infuscated. Wings blackish, a little 

 lighter behind. 



Four specimens, Carlinville, Illinois 

 (Charles Robertson.) 



The neuration is quite as figured by 

 Mik, in the paper above quoted, for 

 the European H. singtilaris Egg. ; the 

 wing and cells are somewhat narrower. 

 The third antennal joint is shorter, and 

 the style longer than in H. tristis. 

 The tarsi show no trace of an empo- 



dium under a compound microscope. 



For the reception of this genus a 

 slight change will be necessary in the 

 table of families recently published by 

 me, as follows : 



29. — Anal cell narrowly open or closed 

 near the border; discal cell present. 



Bombylidae. 

 Anal cell closed near the border; discal 

 wanting. Hilarimorpha Schin. 



Anal cell closed reinote from the border. 



Empidae. 



Baron Osten Sacken published,* not 

 long ago, an elaborate article on the 

 systematic position of the genus 

 Apiocera^ in which he combated the 

 views of Schiner as regards the loca- 

 tion of it tuider the viidaidae, and 

 sought to show that its proper position 

 was among the asilinae. Other auth- 

 ors have not generally been in accord 

 with him. Wiedemann, the first who 

 described any species pertaining to the 

 genus, looked upon the form as that of 

 an Asilid. Westwood, the author of 

 the genus, hesitated between the mi- 

 daidae and fieinistrinidae. Macquart 

 established a new family for the genus, 

 locating it next the therevidae. Phil- 

 ippi described a new species as an 

 Asilid; and Gerstaecker, while re- 

 fusing it admission to the midaidae^ 

 knew not where to place it. Schiner, 

 on the other hand, insisted upon its 

 union with the inidaidae ; Coquillett 

 with the therevidae ; Brauer and Mik 

 as forming a distinct family allied to 

 the therevidae. Finally, I too would
