large hyaline spot on costa. The glandular patch on dorsum of abdo- 

 men (pi. i, fig. 7) is divided into three contiguous plates or lobes, 

 the anterior lobe situated on a backward extension of the 7th and 

 the two posterior lobes on the 8th segment. Each lobe contains a 

 number of closely packed polygonal cells, with an elongate pore in 

 the centre of each cell communicating with a well-defined sublying 

 tubular gland. Notal plates ^"ith numerous spiniform hairs, a 

 transverse series of similar hairs on each of the abdominal sternites 

 and some small hairs on the abdominal tergites. Genital sheath 

 with numerous translucent pores ; intromittent organ terminating 

 in a stout falcate point. Total length (exclusive of antennae) 

 2"5 mm. 



It appears {vide notes by the collector of the material) that 

 the males pass through a nymphal encysted stage similar to that 

 of the females ; but I have, at present, been unable to identify 

 the male cyst. 



Adult female reddish, inclining to brick-red in newly emerged 

 examples, but afterwards darkening to purplish brown. The 

 body, after fertilization, becomes more or less covered with white 

 mealy powder and loose wooly secretion. When boiled in potash, 

 the female gives out a deep carmine stain. Body broadly oval ; 

 slightly narrower in front ; convex above. Margins of abdominal 

 segments slightly prominent. 



Dorsum (pi. i, fig. 8) with a series of ill-defined chitinous plates 

 on the lateral area of all the abdominal segments (except the ist and 

 the terminal), and a transverse median plate on the penultimate 

 and antipenultimate segments. Each of these plates bears a series 

 of stout conical papilliform spines, directed forwards ; a semilunar 

 series of similar spines on the terminal segment ; a small group on 

 the subdorsal area of each abdominal segment ; and other back- 

 wardly directed groups on the lateral and subdorsal areas of 

 the metathoracic and ist abdominal segments. The polygonal 

 character of the chitinous areas (described in my previous paper) 

 is not so noticeable in fully matured examples. Immediately an- 

 terior to each group of spines are some hairs and series of circular 

 pores. There are similar hairs and pores on the median and lateral 

 areas of the remaining segments. Six small spiracles open dorsally 

 on each side of the abdomen, situated — probably — at the interseg- 

 mental areas. There is a gap in the series, between the first and 

 second of these spiracles, but the missing organ is found to be 

 present on the ventral surface. There are, consequently, 7 ab- 

 dominal spiracles on each side, 6 of which open on the dorsum 

 and I on the venter. It is noticeable that, in M. mediterraneus . 

 of the six pairs of abdominal spiracles, the uppermost of the 

 series is ventral, while the remainder assume a lateral position. 



Venter (pi. i, fig. 9) with a curved series of spines on each side 

 of the terminal segment ; a median transverse series on each of the 

 first seven abdominal segments, and a smaller subdorsal series on 

 each side of 2nd to 8th segments ; those on the anterior segments 

 containing one or two spines only, those on the 6th to 8th segments
