species of the Homopterous genus Orthezia. 3801 
curvata, ceteris angustis; segmentis dorsalibus tribus 
vel quatuor anterioribus singulariter lamina levi sub- 
erecta medio valde emarginata fere divisa instructis, 
cxteris rectis nec vel levissime laminatis; marsupio 
longitudinaliter canaliculato. 
Body yellowish or piceous, covered with white cereous 
matter; antenne and legs yellowish, the latter some- 
times piceous, with the extremity blackish ; frontal node 
obtusely angulated, the margins usually recurved so that 
the middle appears sulcate; of the circumferential 
lamine the first four broad, flat, rounded on the front 
edge, projecting; or the first three only have this 
character, the fourth being longer and curved outwards 
(as in fig. 12), the remainder narrower and straight, 
adhering to and not separable from the elongate canali- 
culation of the marsupium ; of the dorsal segments that 
next the frontal node has an erect angulated lamina, the 
next three or four have each a broad, delicate, suberect, 
forwardly directed lamina, which is deeply cleft, almost 
divided, in the middle, so that each side appears with a 
ereatly rounded projecting edge; the other segments 
straight, with, at most, only a slight trace of lamination ; 
at the anal orifice is a short lamina either lying flat or 
slightly elevated ; the marsupium varies much in length, 
sometimes being only half that of the rest of the insect, 
and sometimes, but more rarely, as long as the other 
portion of the insect; the upper surface canaliculate, the 
under surface very convex, the end much recurved. 
Length 13—2 lines. 
I have not seen a male form. There are small indi- 
viduals—1 line long—found with the females, but as all 
I have met with have a trace of a marsupium, they 
cannot be males. The lamellation of this species 1s very 
delicate, and so easily abraded that it is rare to get an 
example quite perfect. 
Karly in April Mr. Norman sent me from Pitlochry 
four specimens (which he found with O. cataphracta), 
with the remark that the lamination differed from that of 
that species, and in May he sent a further supply alive, 
and it was evident he was correct in his observation. On 
the 28th May, at Bexley Wood, Kent, I also had the 
pleasure of finding this species on a bank, among the 
stems of grass and other plants and dead leaves and 
débris ; I have seen examples from Mr. C. W. Dale, and 
I have no doubt it exists in other collections. I have
