meri'dionah's, Serv., pallipes, Duf., Dufourii^ Scudd., and 

 inconspiciia, Kirb. I am more doubtful about castanea, 

 Serv., described from an unknown locality, and vicina, Luc, 

 from Algeria. I am inclined to think that the last insect 

 may possibly be distinct. 



Group of L. tenuicornis. 



19. L. tenuicornis y Borm. 



A slender species, hardly belonging to the genus. 



Group of L. Clarki. 



20. L. Clarki, Kirb. 



De Borraans suggests that this species may belong to Pi/- 

 ragra. It does not agree well either with Pyragra or 

 Labidura^ but one specimen is hardly enough to found a new 

 genus on. 



I add here the description of an uncharacterized form of 

 Labidura : — 



Lahidura truncata, sp. n. 

 Labidura trmicata, Westw., MS. 



^. — Long. Corp. 24-30 millim. ; segm, ult. cum forcip. 

 8-10 millim. 



? . — Long. Corp. 18-20 millim. ; segm. ult. cum forcip. 

 6-7 millim. 



Antennas at least 29-jointed ; body tawny ; the thorax 

 except at the edges, the wing-cases except the borders and 

 suture, and the middle of the abdomen except the last segment 

 above, blackish or reddish brown; last segment of abdomen 

 without anal points, but with a small blackish tubercle above 

 the base of each of the forceps. Forceps triquetral, gradually 

 curved, and crossing at the extremities ; those of the male 

 crenulated on the inner edge to the middle, where stands a 

 projecting tooth (sometimes nearly obsolete), and there is 

 always a second just before the extremity of the forceps ; in 

 the female the forceps are strongly crenulated on the inner 

 side towards the base. The wing-scales in both sexes are 

 usually either absent, or largely developed, covering nearly 

 two segments of the abdomen, and, if developed, tliey are 

 wholly brown except on the edges.
