Among the unpublished notes in manuscript of my late 

 friend M. de Bormans, I find the description of the female 

 with a drawing ; the two specimens which were his types 

 are both females, and he did not know the male, of which 

 I find a single specimen in the Paris collection ; there 

 seems to be little diffei^ence between the sexes ; the 

 branches of the forceps are more strongly curved in the 

 male. In his notes, de Bormans writes, " Cette espece est 

 tres voisine de Br. nigra, Scudder ; elle ne sen distingue 

 que par sa taille, le prothorax plus long, la forme du 

 penultieme segment ventral, la teinte nullement verdatre. 

 Mais c'est surtout la difference extreme d'habitat qui 

 m'empeche de la confondre avec cette espece." The 

 Paris specimen is carded, and so the ventral surface 

 cannot be examined ; the following is from the description 

 of de Bormans : — 



" Penultifeme segment ventral en arc d'ellipse transversal ; non 

 seiilement il recouvre completement le dernier segment ventral, 

 niais il le deborde en arriere d'une longueur egale a celle du dernier 

 segment dorsal." 



" Dessous de I'abdomen de couleur un pen plus pale que le dessus; 

 de meme consistance." 



"Le bord posterieur de cliaque segment du thorax et de I'abdo- 

 men, en dessus et en dessous, est herisse de polls horizontaux, courts, 

 fins, peu serres et pales." 



" Tout le corps de I'insecte, en dessus et en dessous, est moire et 

 reconvert d'un duvet couch e, fauve-dort', et visible seulement a I'aide 

 d'une forte loupe." 



NOTE ON THE GONOLABID^. 



Verhoefif's family Gonolahidx is characterized by the 

 form of the presternum, which is strongly narrowed 

 jjosteriorly, so that the first pair of legs have their in- 

 sertion very close together. In G. pcringueyi, Borm., the 

 anterior coxie are almost contiguous, but in the type of 

 G. hirhyi, Burr, this narrowing is far less marked, though 

 in this species the characteristic apical dilation of the 

 abdomen is very pronounced. A G. javana, Borm., ^ in 

 my possession has also the normal parallel presternum, 

 but a $ of G. silvcstrii, Borelli, has this plate much more
