noj}litis jjhijUocamjja and Eidoplionotus myrmcleon. 9 



much crowded together on costal margin. Hind-wings very small 

 and short, but in the $ larger than in the ^ , and much more pro- 

 minent apically ; costa prominent before middle, but with an abrupt 

 downward flexure just above extremity of discoidal cell; costal 

 nervure not traceable, apparently atrophied ; subcostal nervure arched 

 upward in conformity with costal outline, so that discoidal cell is 

 very broad. Legs rather long, the femora and tibiae hairy, the tarsi 

 long and smooth. 



Abdomen of moderate length in ^, stout, blunt at extremity, 

 hairy laterally and sparsely tufted at tips ; much larger in 9 , with a 

 median dorsal series of conspicuous dense tufts of terminally 

 widened and flattened bristles, and with a very large sub-globose 

 anal cushion of closely packed short hair, sparsely interspersed with 

 some much longer hair. 



In naming this genus Dr. Felder gave no diagnosis, but 

 figured the type, as Ettlo'plionotus niyrmdcon (Reise der 

 Novara, Lepid., Heft IV, p. 4, t. Ixxxii, f. 9, 1874), from 

 a single % sent to him by me in 1867. I am therefore 

 glad to have the opportunity of defining the features of 

 both sexes, and of pointing out that, while not unlike 

 Zeuzera in some respects (and exceedingly like in the larva 

 stage), Euloplionotus is well distinguished by its widely 

 differing neuration ; the radial nervure, so greatly and 

 remarkably developed in Zeuzera, being absent in both 

 fore-wing and hind-wing, and the costal nervure in the 

 hind-wing (also robustly developed in Zeuzera) being 

 aborted, while the subcostal nervure is unusually strong, 

 and arched upwards in accordance with the prominence of 

 the costa. In both sexes the hind-wings are considerably 

 smaller and shorter in proportion than they are in Zeuzera, 

 but this reduction is less marked in the $. The abdomen 

 is smaller than it is in Zeuzera : in the $, too, it is tufted 

 at the extremity ; while in the $ it exhibits not only a 

 dorsal series of long dense tufts of remiform rigid bristles, 

 but also the peculiar character of a very large rounded 

 anal expansion of extremely dense short silky hair, resem- 

 bling that exhibited by various $ $ of the remote family 

 Liparidae. The extraordinary disparity between the sexes 

 as regards size, and the striking dissimilarity of the 

 pellucid almost scaleless wings of the ^ to the black closely 

 vitreous-spotted ones of the $, contribute to emphasize the 

 distinctness of Eulophonotus as a decidedly aberrant genus 

 of Cossidae.
