S6 Indian Museum ISlotes. [Vol. ill. 



Hah. — Od HygropH'ia spinosa at Madras, collected March 14th, All 

 the specimens received were located and partly hidden in the whorls of 

 the spines, leaves^ and flowers of the food-plant, duite fifty pel* cent, 

 of the specimens were infested with a large dipteron^ and some small 

 Hymenopterous insects* 



In its green colour it is like Bactylopw virgatuSi Cockerell, M* S., 

 but this has an eight-jointed antenna^ and the *' tibia about three 

 times as long as the tarsus " (in lit.). 



Two specimens of what I take to be mere varietal forms of the above 

 were found on Fitheeolobium dulce. Externally they differ materially, 

 as are shown at pi. iii, fig. 1^., female's nat. size, and at fig. \e., the 

 same magnified ; structurally, however, they do not appreciably differ, 

 and I hesitate in describing them as new with the limited material at 

 hand. 



Aspidiotus orientalis, n. gp. 

 PI. Ill, fig. 4. 



$ Scale (figs. 4a., 43.) circular, or nearly so, but varying according 

 to position on the food-plant ; brownish yellow, or straw colour, sometimes 

 tinged with reddish-piuk ; exuviae a little to one side, covered with a 

 nipple-like prominence which is darker than the rest ; following this are 

 three concentric circular depressions : the first small and near the 

 " nipple," second well defined and about midway between the two, third 

 often wanting, or but slightly indicated ; margin much interrupted and 

 paler than the rest. Diam. 1-1 1 mm. 



S Adult widely ovate (fig. 4ff ), almost circular; last segment (fig. 

 4^., 4«?.) with three pairs of well-defined lobes : 1st and 2nd each with 

 a deep equal notch at apex on each side ; 3rd smallest, narrow, and 

 notched at apex on the anterior margin only : posterior margin straight ; 

 between each lobe are two slender plates, and immediately preceding 

 the 3rd lobe there are three ; there is a single spine on the dorsal 

 surface immediately over the 3rd plate, and one or more on the margin 

 at the base. 



There are four groups of spinnerets : the anterior laterals consist of 

 5, the posterior laterals of from 3 to 5 : usually 5 ; the anterior group 

 is represented by a single spinneret : no trace of more in any of the 

 many examples examined. There are also very numerous elongated 

 and ovate pores arranged as shown in fig. 4flJ. The plates are very 

 difficult to trace, but the lobes are very distinct. 



$ Scale (fig. 45.) similar to that of the $ but smaller, 



$ Unknown.
