4 ROBERT NEWSTEAD. 



Aspidoproctus neavei, sp. nov. 



Female, adult. Ovate, sides elevated and more or less concave ; dorsum in front 

 relatively low ; abdominal region highly convex. Cephalic or frontal depression 

 well marked. Marginal dentate appendages long, rectangular, widely separated 

 and ivory-like in colour and texture ; there are about 25 of these altogether. Sub- 

 marginal series of processes on the anterior half of the body (four to five in number) 

 not quite so long as the marginal ones, but more robust and often irregularly dentate ; 

 the abdominal series, in continuation, diminishing in size distally. In the median 

 line in front is a pair of small processes and behind them two to three large single 

 ones. Midway between the median and submarginal processes are three very deep 

 pits or depressions. Cavities and hollows coated with creamy white, granular 

 secretion. Colour pale to dark castaneous ; dull orange-crimson in alcohol ; lower 



?;

surface paler. Secretionary operculum relatively small compared with the size of the 

 insect ; it is normal in shape and of a dark brown colour. Antennae of ten segments ; 

 3rd to 7th inclusive broader than long ; 9th and 10th much the narrowest, being 

 about half the width of the 6th, the 10th equal in length to the 6th, 7th and 8th, 

 inclusive ; 2nd nearly twice the length of the 4th ; formula : 10, 1, 2, 3, 9 (6, 7, 8), 

 (4, 5) ; two kinds of hairs present, subspinose forms and simpler slender ones ; the 

 longest of the latter equal in length to the terminal segment, and measuring 1*75 mm. 

 Spines of the gland-tracts (fig. 2, a) incrassated proximally, apex bluntly pointed 

 or sometimes slightly dilated ; those of the proximal lip of the marsupial opening 

 (fig. 2, b) generally curved and more or less spathuliform ; elsewhere, both dorsally 

 and ventrally, the spines are simple and more or less acutely pointed. Glandular
