the c? remote at the base, smooth, deep red, stout, and rather 

 broad at the base, very slightly diverging at first, then strongly 

 arched in a semicircular curve ; in the $ short, contiguous, straight, 

 stout, conical, with a very blunt tooth near the base.

The larv£e resemble the female in the form of the abdomen 

 and forceps ; the colour is light brown, with darker longitudinal 

 bands. 



Ceylon : Peradeniya, in August and November (coll Burr). 



Type in Berlin. 



This species has hitherto been known only from Dohrn's 

 description of the female. Mr. Green found it commonly at 

 Peradeniya, in rotten Avood ; a larva was taken in a termite's 

 nest. 



Of the specimens sent by Mr. Green, there is one male of each 

 form, and four females of the short-winged form, which would thus 

 appear to be commoner, though Dohrn's type is evidently winged. 

 De Bormans incorrectly describes the first antenual segment as 

 brown. 



Ow-ing to its small size, strongly bowed forceps and thick 

 pyriform antennal segments, it is easy to recognize. 



Dohrn describes the sixteenth antennal segment as yellowish^ 

 but this uncertain character is of no value. 



Subfamily III. PSALIN.E. 



The dominant genus of this subfamily is Amsohbis, but Psalis 

 IS chosen as the typical genus because it is the oldest. It has 

 many features in common with the Labidunnce, with which group 

 it is closely allied. 



It is exceptional for the forceps to be slender or remote at the 

 base, whereas the reverse is the case in the Labidurince. 



In this group we find a gradual transition from the fully 

 winged Pscdis to the entirely apterous Anisolabis.

The glandular folds of the third and fourth abdominal segments, 

 which are absent in Labidnra, are often present in Anisolabis ; 

 and Eehn (Proc. Ac. Nat. Sci. Philadelphia, 1903, p. 301) has
