belongs to the same tribe. The mandible (fig. 15) offers no 

 remarkable feature. The maxillulae (fig. 16, Mxl) have prominent 

 apical lobes and strong external ridges ; the tongue (fig. 16, Hy) is 

 markedly widened distally and has a narrow median groove. The 

 maxilla (fig. 16), has — like that of Cremastocephalus — a lacinia sub- 

 circular in outline with short, even teeth, and a lamella with very 

 numerous radially arranged bristles (figs. 17, 18) some of which are 

 elegantly plumose (fig. 19). The end of the gales— like that of 

 Cremastocephalus — is delicately lamelliform (figs. 20, 21, ga), sur- 

 rounding the small conical bristle-bearing palp (figs. 20, 21, p). 

 Study of the jaws in other genera of the Paronellini will show if 

 these characters are distinctive of the tribe as a whole. 



Paronella flava, sp. nov. 

 (Plate Ivi, figs, 24-27). 



Feelers slender, somewhat shorter than body, relative lengths 

 of their segments as 13 : 18 : 13 : 25. Fourth abdominal segment 

 with tergum imperfectly divided, seven times as long as third. 

 Legs with definite joint between shin and foot; foot-claw (fig. 26) 

 with paired basal lateral and internal teeth and an internal distal 

 tooth ; empodial appendage long and slender. vSpring three-quar- 

 ters as long as body, dens half as long again as manubrium ; mucro 

 (fig. 27) with two terminal and two dorsal teeth. 



lycngth 3 mm. Colour yellow with blackish transverse bands 

 on the terga of the metathorax and the first abdominal segment ; 

 tips of antennal segments black- tipped.

This species is clearly related to the preceding which it re- 

 sembles in the structure of foot-claw and mucro, in the absence of a 

 scale-appendage near the base of the latter, in the arrangement 

 and relative size of the ocelli (fig. 25), and in the curious imperfect 

 jointing of the fourth abdominal segment. In build and colour 

 the two insects are of course most readily distinguishable. 



Paronella elongata, sp. nov. 



(Plate Ivii, figs. 28-33). 



Feelers (imperfect) much longer than body. Eight ocelli on 

 each side of head, the two anterior small and two inner posterior 

 very small (fig. 29). Fourth abdominal segment eight times as 

 long as third. Legs very long with definite tibio-tarsal joint. 

 Foot-claw (figs. 30, 31) with paired basal lateral and internal teeth, 

 and an internal distal tooth. Spring nearly three-quarters as long 

 as body; dens a fifth as long again as manubrium, with scale- 

 appendage at base of mucro; mucro (figs. 32, 33) with a small 

 ventral, two terminal and two dorsal teeth.
