 its relatively shorter and less prominent mesonotum. 



PARONELLINI. 



Paronella, Schott, 1893. 



Trichorypha^ Schott, 1893. 



The comprehensive genus Paronella, as now understood, has 

 a wide range over the eastern tropics from West Africa to Malaya. 

 It comprises scaled entomobryine spring-tails with rigid dentes and 

 broadly toothed mucrones, the feeler showing great variety in ap- 

 pearance and length, and the thoracic segments being of normal 

 form. Five Indian species of Paronella have already been des- 

 cribed by Imms (1912). 



Paronella crassicornis, sp. nov. 

 (Plate Ivi, figs. 13-23). 



Feelers robust, as long as head and bod}^ ; relative length of 

 their segments as g : 10 : 10 : 12 ; first segment with long bristles 

 and thick terminal whorls of hairs, second segment with dense 

 rows of bristles beneath, third with some strong long bristles. 

 Fourth abdominal segment with tergum imperfectly divided, eight 

 times as long as third (fig. 13). Legs with definite joint between 

 shin and foot. Foot-claw (fig. 22) with paired basal lateral and 

 internal teeth and an internal distal tooth ; empodium elongate 

 lanceolate with minute external tooth. Spring nearly as long as 

 body; manubrium five-sixths as long as dens (fig. 13); mucro 

 with two terminal and two dorsal teeth (fig. 23). 



lycngth 4 mm. Colour rich brown with dark patches on the 

 prothorax, the base and tip of the first and second and the tip of 

 the fourth antennal segment. The haunches and thighs and most 

 of the three hinder abdominal segments almost black, only a 

 dorsal area on the fourth somewhat paler. 



Localities. — Lower Burma : Dawna Hills, 400-2400 ft., Third 

 Camp to Misty Hollow (F. H. Gravely), four specimens, 22-30 Nov., 

 1911, Ind. Mus. 'rJ'. Sukli, east side of Dawna Hills, 2100 ft. 

 [F. H. Gravely), one specimen, 22-29 Nov., 1911, Ind. Mus. -\-V . 



This handsome spring-tail may be readily distinguished from 

 other species of Paronella by its rich brown colouration, and the 

 thickness of the feelers which have a dense hairy clothing, espe- 

 cially on the second segment. The specimen figured (pi. Ivi, fig. 

 13) has the right feeler with three segments only, the terminal 

 combining the characters of the third and fourth in a normal 

 feeler. There are eight ocelli on each side of the head (fig. 14), 

 the two hind inner ones being much smaller than the others. 



A study of the jaws has been made, and it will be seen that 

 they resemble rather closely those of a species of Cremastocephalus 

 (Carpenter, 1916, p. 46, pi. xviii, figs. 78-81), a genus of which
