Assistants (Mr. Y. Ramachandra Rao), who reports that they 

 were found " while digging the ground for the egg masses of the 

 ' Deccan Grasshopper.' This form was found in all soils— black 

 and red, but seems to be more abundant in clayey soils." He 

 notes that adult males and females were emerging early in June, 

 at which time the cysts '' were somewhat reddish in colour." 

 Earlier in the year (in February) the cysts were of a " yellow 

 colour with a pearl-like lustre," and were found, when broken, 

 to contain nothing but a milky fluid. 



Margarodes papillosus must be very closely allied to M. 

 mediterraneits of Silvestri (described very fully in the '' Bul- 

 letino della Societa Entomologica ItaUana," xxxviii, 1906, 

 p. 140 et seq.). It differs principally in the colour of the adult 

 female, which is creamy white or straw-coloured in the Mediterra- 

 nean, and brick-red or purplish red in the Indian species. The 

 disposition of the spines is approximately the same in both 

 species, but they appear to be more numerous and more strongly 

 developed in the Indian form. I am, unfortunately, not in a 

 position to compare the larval characters, which are quite pecu- 

 liar in M. mediterraneus. Silvestri states that his species has 

 8 pairs of spiracles, against the 9 pairs found in papillosus. It is 

 interesting to note that, in both species, one of the abdominal 

 spiracles is placed on the venter. 



Margarodes niger, Green. 

 (PL iii, figs. 22-35 ; Pl- iv, figs. 36-45-) 



Male not known. 



Adult female (pi. iii. fig. 22) oblong oval, sHghtly narrower in 

 front ; subglobose. Colour creamy white, thickly covered with pale 

 reddish brown, very fine but shaggy hair, which is denser and of 

 a deeper colour on the thoracic area. Claws dark brown. 



Antenna (pi. iii, fig. 23) 6-jointed; weakly chitinized ; all the 

 joints short (broader than long) ; ba^al joint largest, the remainder 

 gradually diminishing in size to the extremity ; two or three long 

 fine hairs and a few spines at apex of 6th joint, a transverse 

 series of slender truncate spines on 2nd to 5th joints, several long 

 fine hairs on the side of the 2nd and 3r(l joints, and a transverse 

 series of similar hairs on the 1st joint. 



Anterior limb (pi. iii, fig. 24) large and stout, the claw (pi. iii, 

 fig. 25), which includes the tarsal joint, densely chitinous, of a pecu- 

 har form that is quite unlike that of any other known species of 

 Margarodes. It is strongly curved in two directions, both the 

 inner face and the apical maigin being concave. It his almost 

 the appearance of being chelate, but the opposing points (the 

 outermost of which is longer and more sharply pointed) cannot be 

 approximated. Tibia represented by a small triangular joint 

 between the claw and the femur, with a group of minute pores on 

 its outer face. Femur with some long fine hairs on the disc of the 

 inner face and near the apex of the outer face. Mid and hind
