amber), but body apparently without scales ; stili can only be' 

 seen at apex of abdomen, and certainly are absent from the 

 middle segments. In the following descriptions the measure- 

 ments are all in microns: 



Antennae as usual in the family, with short setse ; maxillary 

 palpi 5-jointed, the firsi joint short, the others measuring, (2) 

 96, (3) 88, (4) 96, (5J 160 ; width of head about 400 ; width of 

 thorax in middle about 640 ; width of abdomen about 528 ; 

 long slender hairs project from sides of thorax as in Silvestri's 

 figure of Lain])ropholis^ only they are more numerous ; coxge 

 and femora stout, the legs essentially as in Lepisma^ the only 

 noteworthy feature being the extremely oblique end of first 

 tarsal joint ; hind tibiae 304 long, their tarsi 320 ; cerci about 

 1440 long, with fine bristles, and three very long bristles, more 

 or less broadened apically, placed about 320 apart ; caudal stili 

 about 240 long, not counting the apical bristle, which is about 

 65 ; inner process of caudal subcoxee long and pointed, its 

 length about 160. 



Burmese amber, from R. C. J. Swinhoe ; in the same piece 

 as the type Eleciofcenns^ and 28™™ from it. This may have 

 lost all its scales, but if it was a scaly form, it is surprising that 

 no scales are to be found, even in the amber round about it. 

 Lepidothrix^ from Baltic amber, is without scales, but is in 

 other respects very distinct from our insect. Possibly the 

 Burmese species should be placed in a new genus. 



Hemiptera. 

 DisphcBrocephaliis new genus (Enicocephalidge). 



Kelated to Enicocephalus^ but differing thus : head strongly 

 constricted behind eyes, so that there is a slender neck before 

 the bulbous expansion ; thorax long and relatively slender, 

 much longer than wide, with a marked posterior constriction ; 

 wings (the specimen apparently adult) not developed, repre- 

 sented by pads ; rostrum long, in specimen seen extending 

 straight out from head; antennse long and very slender; 

 anterior tibiae (shown greatly foreshortened in figure) broadened 

 and angularly produced apically, much as in Enicocephalns^ 

 but their tarsi long and narrow, with two slender straight 

 claws, one much longer than the other ; hind femora very 

 stout, with an obtuse angle beneath. The head and thorax are 

 delicately hairy ; the antennae are not hairy. Type the follow- 

 ing. 



DisphcBrocephahis constrictus new species. 



Length (to end of extended proboscis) 5™'" ; the following 

 measurements are in microns : Eyes to end of first antennal 

 joint 640 (it is not possible to see quite clearly where the joint
