Subfamily I. Brachtlabinm. 



The genus Isolabis, Verb., falling into the same subfamily 

 as Brachylibis, Dohrn, it is necessary to suppress the name 

 Isolabiiife for the subfamily and to substitute that of 

 13rachylabinff>. 



In the cylindrical form of the body, the few antennal 

 segments, the triangular head, large eyes, attenuated abdo- 

 men, excised last dorsal segment, and ta})eiing, slender, 

 arched loiceps, it is very well characterized. All the members 

 liave a very distinctive ap[)earance and cannot be confused 

 with any other group. 



Genus I. Verhoebtia, nov. 



Antennae segmento 3 longo, saltern duplo longiori quam latiori, 4 

 longiori quam latiori, 5 tertium longitudiiie subajquanti ; meso- 

 notum lateribus baud carinatis, ad Lumcros ipsos obtuse tumido- 

 elevatis, elytris rudimentariis instructum, cseteris cum generibus 

 Isolabide et Bracli)jlahide congruet. 



As Verhoeff, in characterizing the Tsolabid*, sa3^s " Elytra 

 imdFliigel fehlen vollig," I erect this new genus for Brachy- 

 hihia sjostcdti, Borg (Ark. f. Zool. i. p. 568, Taf. xxvi. 

 lig. 2, 1904), from the Cameroons. Borg gives a good 

 figure, and the rudimentary elytra are plainly shown like 

 a Y-shaped suture on the mesonotum. Their form some- 

 what recalls that of the same organs in Karschiella, in which 

 the chief sign of elytra is a narrow excision in the posterior 

 border of the mesonotum. My friend Dr. Borelli, of Turin, 

 has sent me a specimen from Fernando Po, and 1 have in 

 my own collection one labelled " Cameroon."
