I'SEUDISOLABIS. 105 



brown, very finely punotulate, svibparallel-sided, slightly narrowed 

 apically ; glandular folds not developed. Last dorsal segment more 

 than twice as broad as long, rectangular, posterior margin truncate 

 in the middle, the angles obliquely truncate, slightly tumid over 

 the roots of the forceps. Penultimate ventral segment transverse, 

 very broadly rounded. Pygidium typical, somewhat tumid beneath. 

 Porceps with the branches remote at the base, of circular cross- 

 section, straight at first, incurved at the apex, quite simple.

Type in the author's collection. 



This species closely resembles P. burn but is narrower in build, 

 of a uniform dull red brown instead of shining black, and tlie 

 forceps are quite straight for the greater part of their length, 

 being only arcuate at the apex itself. 



Subfamily VI. BRACHYLABIN^E. 



The members of this family have all a very characteristic 

 appearance and close superficial resemblance to each other. 



The old genus BracJiijlahis of Dohrn, as restricted by de Bormans, 

 has been revised and split up, and Verhoeff's Isolabicke incor- 

 porated. The genus Brach)/Iabis itself is not represented in the 

 Indian fauna. 



The family is characterized by the total absence of organs of 

 flight, long slender legs and tarsi, even the second segment 

 being elongate, triangular head, cylindrical body, tapering at 

 the apex, paucisegmentate antennae, long narrow pi-osternum, 

 equally broad and lorig meso- and metasterna, broad and rounded 

 penultimate ventra' segment, and sinuate, concave last dorsal 

 segment, produce'^l into a short pointed lobe on each side ; the 

 forceps slender, cylindrical, tapering, unarmed and arcuate. 



They are all very dark brown or nearly black insects. The 

 surface is usually very densely pitted and punctulate, and often 

 clothed with a dense pubescence, which is rapidly rubbed off and 

 lost in cabinet specimens. 



A remarkable feature in some genera is the form of the eyes, 

 which are elliptical and unusually large, reaching backwards 

 almost to the posterior angles of the head, so that they are 

 situated laterally instead of anteriorly.
