him to this insect, and to publish the diagnosis of the adult which has been drawn 
up from one of three examples which were colleected by Dr. Fülleborn, to whom 
we must give the credit of the discovery of this very remarkable inseet. 
Aspidoproctus armatus n. sp. (Newstead). 
Female adult (fig. 3). Elongate, narrowed posteriorly; margin in front more 
or less truneate; sides broadly.concave and deeply and coarsely punctate. Cephaliec 
area sloping suddenly downwards the area defined by two widely separated and 
rounded ridges, most clearly defined towards the 
margin, each terminating with a short, stout, tooth- 
like waxen appendage; thoracic area with two large 
transverse ridges each bearing four Jarge bluntly pointed 
processes: one lateral and two median; abdominal 
area flat, tapering more or less posteriorly; margin 
forming a distinct ridge along which are six small and 
bluntly pointed processes of which the first and last 
are the largest; margin with a series of blunt tooth 
like waxen appendages, many of which are bifid. The 
whole of the dorsum bears a thin coating of greyish 
granular wax, but is darker and more homogenous 
over the blunt processes. Venter flat or concave, 
mealy. Colour in alcohol dull erimson; venter terra- 
cotta red. Derm of venter thickly studded with short 
stout spines, scattered between them are numerous

small eireular spinnerets, and at greater intervals large, clear, circular glands; besides 
these there are also a number of large subeutaneous bell-shaped organs (? glandular) 
having a finely retieulated lip; the relatively small area protected by the secretionary 
opereulum almost covered with eircular spinnerets, and arising from between them 
many slender hairs. Thoracie spiracles large. Antennae, of 10 segments of which 
the terminal one is much the longest. 
Length 12—17 mm; width 8—12 mm; height 6—8 mm. 
Habitat: D. Ost-Afrika, Amani. Au. Acacia, XL. 03. Prof. Vosseler 8. G. 
Nr. 938/06. 
Easily distinguished by the curious armature of the dorsum which gives the 
insect a very formidable appearance. 
Aspidoproctus pertinax, Newstead. 
A single adult female associated with Aspidoproctus mawimus. 
The only information aecompanying this specimen is „Langenburg, D. Ost- 
Afrika, Dr. Fülleborn, S. G.“ (Nr. 2.) 
The co-types were colleeted by H. B. M. Commissioner A. Sharpe, C. B., at 
Zomba, Central Africa in 19008), and until recently this has remained the only 
known locality for this interesting coceid.
