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



Stature small and rather slender. Antennae with 16 

 segments : the twelfth is yellow in the type specimen, the 

 rest black ; the third segment is quite twice as long as broad, 

 the fourth shorter: the head is small and quite typical. 



Pronotum about 1^ times as long as broad, slightly broader 

 posteriorly than anteriorly ; median suture almost obsolete. 



Mesonotum with lateral keels sharp, gently curved, obso- 

 lete just before reaching the posterior margin. 



Metanotum strongly sinuate posteriorly. Femora and 

 tibia? black, each with a yellow ring at the apex. 



Abdomen slender, with distinct lateral tubercle on the 

 fourth segment only ; last dorsal segment typical, excavate, 

 and attenuate. 



Forceps with branches remote at the base, cylindrical, 

 gently incurved, and crossing at the apex. 



Nossi-Be* (Voelizkow). 



The single male specimen which is my type is out of de 

 Bormans's collection, and was labelled by him " Brachylabis 

 punctata, Dubr." It differs, of course, from the true punctata 

 in the generic characters, but has a strong resemblance to 

 Br. caudelli from Burmah, which de Bormans confused with 

 B. punctata. It differs from B. caudelli in the longer and 

 narrower pronotum and in the evanescence of the meso- 

 thoracic keels. 



3. Brachylabis chilensis } Blanch. 



The literature of this species is quoted by de Bormans and 

 Kirby. It is the largest of the genus and quite different in 

 appearance from B. nigra, the only other known American 

 species. It occurs in Chili, Ecuador, and Brazil, but does 

 not seem to be common. 



4. Brachylabis togoensis, Verb. 

 Ctenisolabis togoensis, Verh. SB. Ges. nat. Fr. Berlin, 1902, p. 14. 



This species is only known to me by VerhoefFs description 

 and a sketch of the type. It is one of the smaller species 

 and appears to be allied to B. nigra. 



5. Brachylabis nigra, Scudd. 



Originally described as a Cylindrogaster, this is a true 

 Brachylabis. It is easy to recognize, as it is stouter and 

 smaller than the only other known American species, 

 B. chilensis, and has a characteristic greenish sheen ; but 

 this is not always preserved in cabinet specimens. 



It occurs in northern iSouth America.
