and I have no doubt but that it will be found throughout 

 the subfamily ^). 



The metamorphoses may be briefly detailed : 



The egg (fig. 5 a and h) is obtusely flask-shaped, flattened 

 down ventrally ; the lid is provided with a small knob. Colour 

 brown ; chorion well chitinized, with finely reticulated surface 

 (fig. 6) composed of hexagonal and pentagonal areas. Size 

 1,2X0,5 mm. The eggs are more or less covered by a whitish 

 exudation. 



The nymphs in the two last stages are very similar, and 

 are also very similar to the adult, except that the dense 

 hairiness of the adult is absent to a very large degree in the 

 nymph (fig. 7) 2). 



The antennae are 4-segmentate, the first segment being as 

 in the adult, the second much thicker than in the adult, 

 about twice as long as the middle tibiae, and tapering sud- 

 denly a little before the apex. These segments are almost 

 hairless (unless the hairs have become detached, which I do 

 not think), but have very numerous tubercles from which 

 doubtless arise the hairs in the adult stage ^). The third and 

 fourth segments are minute and the third is inserted basal of 

 the apex of the second. The pronotum is very transverse, 

 laterally very widely laminate, nine times as wide as its middle 

 length, and twice as wide as the head and eyes. The entire 

 nymph is sparingly hairy (see note), except the abdomen 



ij Westwood (1874 Thesaurus Ent. PI. 36, fig. 10«) figured the trichoma, but 

 did not realize its importance and interest. 



") Evidently the nymphs examined by INIr. Kirkaldy liad the hairs rubbed 

 off. In the s; ecimens I kept back the pilosity is not less than in that of the 

 adults, and as far as the body is concerned the nymphs even sui-pass them in 

 hairiness. (E. Jacobson). 



3) As pointed out the nymphs described by Air. Kirkaldy were partly 

 deprived of tlieir hairy covering. In fact the antennae are covered with hairs 

 over their entire lengili, each of the numerous tubercles mentioned forming 

 the basis of a hair, (E. Jacobson).
