G-enus XXIX. Sphingolabis, Be Borm. 

 Be Borm. Ann. Soc. Ent. Belg. xxvii. p. 59 (table) (1883). 



Type, 8. furcifera, De Borm., from Sumatra. 



This genus has never been properly characterized, and I cannot 

 venture to do this now, because the typical species is not before 

 me. Sphingolahis, however, removes from Forjicula all the 

 species not yet assignable to other described genera in which the 

 male forceps are divergent at the base ; and though it may now 

 be used provisionally in this wide sense, it must later on be sub- 

 divided into numerous smaller genera. 



Sphingolabis taeiegata, sp. n. 



Long. corp. 15 millim. ; segm. ult. cum forcip. 5 millim. 



Female. Reddish brown, the pronotum (except the margins), 

 the sides o£ the basal segments o£ the abdomen, and the last 

 segment shading into blackish ; antennae at least 12-jointed, the 

 joints comparatively short ; joints 10 and 11, the lateral and 

 hinder margins of the pronotum, and the penultimate segment 

 of the abdomen pale testaceous ; tegmina tricoloured ; a broad 

 reddish stripe on the suture, a yellowish-testaceous stripe in the 

 middle, and the outer edge blackish ; wings reddish, the borders 

 right round to the sutural margin yellowish testaceous ; legs 

 reddish, the knees and tarsi shading into testaceous ; pygidiuiu 

 rounded ; forceps rather long, moderately stout, not closely ap- 

 proximating at base, unarmed, slightly incurved, and meeting at 

 the tips. 



Sab. Sierra Leone. 



Somewhat resembles S. africana, Dohrn. 



Sphingolabis bipaetita, sp. n, 



S . Long. corp. 13-16| millim. ; segm. ult. cum forcip. 6-7g 

 millim. $ . Long. corp. 10 millim.; segm. ult. cum forcip. 3 millim. 



Head and front o£ pronotum pale red above ; sides and hind 

 part of pronotum pale testaceous, the two colours sometimes 

 separated by a dusky crescent ; antennae and abdomen darker red, 

 the lateral tubercles on the 2nd and 3rd segments of the abdomen 

 surrounded with blackish ; tegmina and wings pale yellovr, the 

 former with a reddish or brownish band on the suture hardly 

 extending to the wings ; legs pale yellow. Pronotum as broad 

 as the head, subquadrate rounded behind ; tegmina nearly three
