NEW SPECIES OF NOCTURNAL MOTHS OF THE GENUS 

 CAMPOMETRA, AND NOTES.

The genus Campometra was described in 1852 by Guenee,^ and the 

 sole species and therefore generic type, amella, was iigured (PI. XYIII, 

 fig. 8). Mr. Grote never positively identified this species, although the 

 picture is good and the markings are characteristic. In the Neumoe- 

 gen collection he did note, however, to a specimen of Uuholina stylohata 

 a suggestion that it might be C. amella, and that proves to be correct 

 without reasonable doubt. I have not seen the Guenee type, but both 

 description and picture apply to stylohata and to nothing else. The 

 type of stylohata I saw in the collection of the British Museum, and on 

 direct comj)arison with the type of Homoptera integerrima Walker 

 found the two identical. 



The synonymy then seems to be fairly well established, as follows: 



Campometra amella Guenee, Sp. Gen. Noct., Ill, 1852, p. 25, pi. xviii, fig. 8. 

 Homoptera integerrima Walker, Cat. Brit. Mus., Het., XIII, 1857, p. 1057. 

 Homoptera stylohata Harvey, Can. Ent., VIII, 1876, p. 155. 

 Euholina stylohata Grote, New List, 1882, p. 42. 



The genus EuhoUna was described by Harvey^ for his species impar- 

 tialis, described at the same time, and that is therefore the type of the 

 genus. In 1882 Mr. Henry Edwards described EuhoUna mesJcei, and in 

 the same year Mr. Grote referred Homoptera mima Harvey to EuhoUna 

 in his New List; the genus thus containing four species, two of which 

 its describer had not considered as referable to it when they were 

 characterized by him. 



E. impartialis differs in color and general appearance from the allied 

 forms, and on the fcDiale, which only I have at hand, the middle tibiae 

 are lengthily spinulated, the clothing close, the armature in a single 

 series and very prominent. 



Campometra amella has the legs all shorter and quite densely clothed 

 with hair and scales, the middle tibiae with apparently a few scattered 

 spinules. In the male there seem to be no sexual tuftings on this 

 member.
