Aphorista, Gorham. 



A. vittata, Fabr. (hg. 53, larva; fig. 54, pupa; fig. 55, 

 beetle), is a smooih shining insect, about a quarter of an 

 inch in length, in colour reddish above, the elytra with a 

 common sutural black stripe, and each with a shorter 

 lateral one. The antennae are nearlv black. 



Mycetina, Muls. 

 The little M. perpiilchra, Newm., belongs here, and 

 well deserves the name. It is .16 in. long, the head is 



black, the thorax red, either with or without a discoidal 

 vitta. The elytra are bUck, each with two red spots, the 

 anterior subhumer.il in position and transversely elongate 

 in form. This species is represented in fig. 56. M. Hornii, 

 Cr., will doubtless be taken in British Columbia, and differs 

 in having a triangular humeral spot. 



Epipocus, Germ. 



Probably through error, the Texan E. ductus, Lee, is in the Canadian 

 lists. It is a large ferruginous pubescent species, .4 in. long, the thorax 

 with four black marks, the elytra with the disk (except sometimes the 

 sutural region) black. In Texas I have found it under logs near fungi 

 and have described and figured the early stages, which resemble those of 

 Aphorista vittata. 



Endomychus, Panz. 

 E. biguttattis, Say (fig. 57), has the thorax black, the 

 elytra red, with two black spots on each, the posterior 

 larger. Length, .16 in.

The Erotylidce are allied to the Endoviychidce, but the 

 Fig. d7. ta^j-si are four or five-jointed, never three-jointed, as is 



apparently if not actually the case in the latter family. The pronotum 

 has not the sub-basal transverse impression and two longitudinal lines so 

 often seen in the Endomychidte, and the form is usually more elongate 

 and more convex. Comparatively little is known of the larvae of our 

 native species ; that of Languria (fig. 58, Languria Mozardi in all stages) 

 is elongate, and, in the species figured, about .32 in. long; the form is sub- 

 cylindncal, only the anal segment being narrower than the preceding 

 joint ; the colour is light yellow, the mandibles and anal horns (which are 

 acute and curved upwards) brown. It feeds in the stems of clover, and
