processes stout ; some strong but short bristles on dorsum 

 besides tlie erect stiff hairs. 



Length 7*5-8 ram. 



Type, male, Valle del Lago Blanco, Chubut, Patagonia 

 (J. Kosloivsktj). Allotype, Port Famine, Tierra del Fuego 

 {(^un-les Duriviii). One female paratype, Valparaiso, Chile 

 (^C/iar/es Darwin). 



This species is a very striking one, both as to colour and 

 structure. It would undoubtedly be placed in Lasiups or 

 Phaonia by other authors, but my recent diagnostic Avork on 

 this family has convinced ine that such a course is not per- 

 missible, and I therefore erect for its reception a new genus 

 which 1 have dedicated to the honour of the collector of the 

 females above listed. 



The genus Phaonia finds its greatest development in the 

 northern half of both hemispheres, there being comparatively 

 few species even doubtfully referable here in the southern 

 half of either, and Lasiops is entirely northern so far as I 

 know now. 



Subfamily Lisping. 



This subfamily, which is distinguished from its allies by 

 having the palpi flattened and dilated at apex and the 

 pteropleura with some erect hairs in centre, as well as the 

 eyes widely separated in both sexes, is widely distributed, 

 occurring in every faunal region in the world. There are 

 about 150 species described, the greater number occurring in 

 the Pahearctic region and in Africa, while there are but four 

 described from South America. Only one genus is repre- 

 sented, but there are some very aberrant forms, if we accept 

 the genotype as the criterion of the genus. One of the most 

 aberrant species known to me 1 have in this paper used as 

 type of a new subgenus. 



Subgenus Xenolispa, nov. 



Subgeneric characters. — This subgenus differs from Lispa 

 (sens, str.) in having the sterno-pleura with but one bristle, 

 on the upper posterior angle. The presence of but one pair 

 of postsutural dorso-central bristles and the absence of long 

 bristles on the postero-ventral surface of the fore femur, as 

 well as the distinct narrowing of the first posterior cell of 

 the wing, serve to distinguish the subgenus from most of the 

 species of Lispa. 



Genotype, the following species.
