On some Pupipara jjorrtsiitc iipon CMroptera. 

 By Dr. F. Etjdow. 



To the few animals of this kind described by Nitzsch, Frauenfeld, 

 "Westwood, Kolenati, and others, I am able to add some which have 

 not yet been described, which live parasitically upon bats, chiefly of 

 America, and the original specimens of which are probably pre- 

 served in the collection founded by H. Schilling in the Hamburg 

 Museum. 



1. Strehla longipes. Belonging to the group B of the convex forms 

 of Xolenati. Ochreous, tolerably thick, very rough ; the abdomen 

 beset with dark-brown thick spines, standing singly among weaker 

 ones. All the horny parts coriaceously wrinkled. Head elongate 

 shield-shaped, nearly pointed in front, with long brown setse. Pro- 

 boscis strong, projecting acutely. Thorax cordiform, longer than 

 broad, slightly convex, with long bristles. 



Legs tolerably thick ; femora and tibiae clavate ; tarsus thin ; 

 claws very strong, strongly bristled, with single, nearly black spines 

 among the bristles. Wings tolerably transparent, pale ochreous, at 

 least one third longer than the abdomen, nearly elliptical, with a 

 rather thin, laterally margined basal piece ; fringe of hairs on the 

 sides tolerably long, but fine, as is also the hairy covering of the 

 whole surface. The venation is different from that of Frauenfeld's 

 S. Kollari ; the two middle veins, which are not very prominent, 

 are furcate almost at the base, the others simple. Halteres very 

 small. 



Abdomen elongate-ovate, with the segments indistinct, finely 

 fringed at the sides ; terminal segment with some long bristles and 

 strong warts. 



A female from Phyllostoma Jiastatum, 0-75 millim. A comparison 

 with the only other known species admits of no confusion between 

 them. 



2. Liptoptena duhia. Ochreous, strongly bristled. Head broad, 

 particularly thick in the region of the eyes. Antennae very broad, 

 especially the last joint, and provided with strong spines. Strongly 

 bristly and spinous. Proboscis very long and acute. Thorax much 

 broader, nearly quadrangular, with rounded sides. Ground-colour 

 ochreous, with some curved, transverse, and angulated longitudinal 

 furrows of a red colour. Legs moderately thick and long, strongly 

 bristly, with clavate joints and sharp claws. Wing-rudiments 

 scarcely one fourth the length of the abdomen, rounded elliptical, 

 with long but fine setae. Abdomen very thick, broadly ovate, with 

 the segmentation indistinct, on the sides finely, on the back strongly 

 bristled, and with isolated long spines ; terminal segment small, 

 with two thick obtuse tubercles, with very long setae. 



Length 0*5 millim. On Noctilio dorsatus from Venezuela. 



In our specimen, besides the wing-rudiments, there are on the 

 thorax very small rudiments of halteres, attached laterally, of a very 

 narrow oval form, and only a little smaller than the wings them-
