Aluscina. - - Until within a few years our species of J\fns- 



cina have been referred 

 to Cyrtoneura. Such au- 

 thorities as van der Wulp 

 and Williston are of the 

 opinion that Cyrtoneura 

 is a badly conceived genus 

 and that the name should be

 ^4-jil' l~< f erred to it being divided among 

 the genera Mnscina, Clinopcra, 

 HcinicJilora, and Morellia. Simi- 

 larly, Cyrtoneurina should be 

 dropped as a generic name, its 

 species being distributed among 

 some of the genera just mentioned. Following van der Wulp's 

 views in cases where the species are unknown to me, the fol- 

 lowing are the known North American species of Mnscina: 

 stabulans Fall., assimilis Fall., mcxicana Macq., pallidicornis

 The species that I know may be 

 separated by this table : 



1. Legs wholly or partly yellow; 



palpi yellow . . . .3 



2. Legs wholly black . . .4 



3. Antennae brown ; three pairs acrosti- 



chal bristles cephalad the trans- 

 verse suture ; prostigma brown ; 



humeri concolorous with thorax . . . stabulans Fall. (Fig. 4) 



Antennae pale yellow ; one pair acrostichals cephalad the suture ; prostigma 



whitish yellow; humeri not concolorous with thorax texana nov. sp. (Fig. 7)
