Aet. XXV. — Notes on a Collection of Pselaphida} frovi the 

 Neighbourhood of Cleveclon, Southern Wairoa. 



By Captain T. Begun. 



lEcad before the Auckland Institute, 19th August, ISS'J.] 



Me. Geoege Muneo, of Clevedon, having been kind enough to 

 carry out my \Yishes regarding the collection of PseUqjtiidce, 

 I am thus in a position to add three new species to our 

 already tolerably large list. These species, whose descriptions 

 are attached, have been named as follow : Bryaxis munroi, 

 B. forficulida, and B. foveatissima. The first-named species is 

 dedicated to the discoverer. The male is remarkable on ac- 

 count of the armature of the front coxae, which bear long 

 spine-like processes ; by the presence of a pair of acute slender 

 tubercles on the hind part of the basal segment of the abdo- 

 men ; and, further, by the first joint of the posterior tarsus 

 being furnished with a slender, elongate, spiniform protube- 

 rance, several times longer than the joint itself. In other 

 respects the insect, or, more correctly speaking, the body, 

 appears somewhat similar to Bryaxis dispar, B. impressifrons, 

 and B. fraudulcnta, but the structure of the antenna is essen- 

 tially different. I need not in this place enter into details 

 pertaining to these important and curiously-formed organs, as 

 they are fully described in the annexed papers. The second 

 species, Bryaxis forficulida, is another curious well-differen- 

 tiated form — in fact, it is, I believe, without parallel among 

 the group Pselaphldce — I had almost stated, among the order 

 Coleoptera, and might indeed have said so had I not recol- 

 lected that an Australian genus of the Bhyncopliora, or weevil 

 tribe, bears nearly similar organs. The hind-body and elytra 

 conjointly form an elongate-oval figure terminating in a pair 

 of appendages, or forceps, not unlike those of an earwig — 

 indeed, so much alike are they that the specific name is 

 intended to indicate the resemblance. I am sorry to say I 

 have seen but one specimen, the only one that has been found
