DESCRIPTIONS OF GENERA AND SPECIES. 255 



the male resemble the notogastral hairs of the female. 

 Penis (PL XI, fig. 7) slightly curved, and supported 

 on a horseshoe-shaped sclerite, to which tendons are 

 attached; it is placed between the epirnera of the 

 fourth pair of legs. The legs are longer and thicker 

 in proportion than those of the female, and the two 

 front pairs are thicker than the hind pairs. 



The Nymph and Larva would readily be known 

 from their resemblance to the adult male, but the body 

 hairs are fewer, shorter, and far less pectinated ; in 

 fact, they are only slightly villous. 



Habitat, In hay and fodder, usually abundant 

 when it occurs at all. I have found it in great quanti- 

 ties in old honeycomb. It has been recorded in 

 Germany and Italy (subject to what is said above 

 relative to the synonymy).

I have not ever been able to obtain a copy of 

 Armanelli' s original paper. It was published separately 

 in a small town in Sicily, and is extremely difficult to 

 obtain, but I believe that Dr. Armanelli was a pupil of 

 Prof. G. Canestrini' s, and that practically the whole of 

 Armanelli' s paper is incorporated in Canestrini' s two 

 works above referred to ; Armanelli supplied Canestrini 

 with specimens. Relying, therefore, on Canestrini's 

 publications as a correct representation of Armanelli' s, 

 it is necessary to point out that there is a grave error 

 in the original description of the species, and in 

 Canestrini's reproduction of it, and in the plates which
