Mr. M. Burr — Notes on the Forficularia. 24.9 



Mesonotum with distinct sharp lateral keel on each side. 

 Third antennal segment a little longer than broad. 



The above chaoacters, by which Verhoeff distinguishes his 

 genus Ctenisolabis, for the single species Ct. togoensis, are 

 common to B. c/tilensis, Blanch., which is the type of Brachy- 

 labis. Consequently the former genus falls as a synonym. 



Brachylabis in its true sense also includes B. nigra, Scudd., 

 B. malgacha, Borm., B. caudelli, sp. n. (vide infra), 

 B. bifoveolata, Bob, and B. voeltzkowi, sp. n. (vide infra). 



1. Pronotum longius quara latius. (Anteunarum 

 segmentum 3 quam 2 duplo longius.) 

 2. Mesonotum carinis obtiiais usque ad marginem 

 posticum productis ; (pedibus iaf uscatis : 



species rnadecassa) 1. malgacha, Burr. 



2.2. Mesonotum carinis acutis ante marginem 

 posticum evanescentibus. 

 3. Statura gracili ; genubus flavis : species 



madecassa 2. voeltzkowi, sp. n. 



3.3. Statura fortiori; genubus infuscatis: species 



americana meridionalis 3. chilensis, Blanch. 



1.1. Pronotum vix longius quam latius. 



2. Anteunarum segmentum 3 vix longius quam 

 latius. 

 3. Frons punctis impressis postice conflu-

2.2. Antennarum segmentum 3 duplo longius 

 quam latius : species asiatica. 

 3. Pedibus unicoloribus ; abdomen segmen- 

 tum 4 pliciferum 6. bifoveolata, Bol. 



3.3. Pedibus fulvo-annulatis; abdomen segmen- 

 ts 3 et 4 pliciferis 7. caudelli, sp. n. 



1. Brachylabis malgacha, Burr. 



Brachylabis malgacha, Burr, Trans. Ent. Soc. London, 1904, p. 292. 



This species has a distinctive appearance ; the feet are 

 slenderer and longer than in the other species, the antennae 

 are not so thick, and the keel of the mesonotum is more 

 obtuse. It is recorded from Madagascar and Diego Suarez. 



2. Brachylabis voeltzkowi, sp. n. 



Statura minori, graciliori ; antennas 15 segmentis, apice fulvo- 

 annulatae ; pronotum valde longius quam latius ; mesonotum 

 carinis acutis, paullo ante marginem posticum evanescentibus ; 

 . femora tibiseque t'usca, apice fulvo-annulata. tf . 



Long, corporis 11 mm.
