NEW INDIAN COCCIDS. 



BY E. ERNEST GREEN, F.E.S. 



The two new species of Aspidiotus described below are from a 

 miscellaneous collection of Coccids, chiefly from India, kindly handed 

 over to me by Dr. F. Moore, F.Z.S. 



Aspidiotus Moorei, n. sp. 



Female puparium (fig. 1) very inconspicuous ; rugose and coloured like the bark 

 upon which it rests ; circular, flattish above, slightly 

 concave below ; very solid and opaque, the margin 

 thicker than the median area. Pellicles reddish-brown, 

 inconspicuous ; sometimes concealed by a layer of se- 

 cretion ; one or both sometimes absent. The insect lies 

 in a shallow depression excavated in the bark, and coated 

 with whitish or greyish secretion deposited in distinct 

 concentric rings. Diameter, 2'50 mm. 



, 1 Male puparium not observed. 



Adult $ (fig. 2) reddish-brown, flattened, entirely chitinous ; dorsal surface 

 highly polished. A deep lateral notch and transverse 

 groove behind the cephalo-thoracic segment and another 

 behind the metathorax divide the body transversely into 

 three subequal parts ; the first consisting of the head 

 and prothorax, which is rounded in front and nan-ower 

 than the second section comprising the meso- and meta- 

 thorax. The third section consists of the abdominal 

 segments, which are all united into a single piece forming 

 the pygidium, the suppressed segments being indicated 

 by transverse curved grooves on the surface which do 

 not reach the margin. There are two large well defined 

 circular depressed areas in front of the rostrum, of a 

 paler colour than the surrounding parts. There is a moderately large group of 

 parastigmatic glands round each of the anterior spiracles. No circumgenital (grouped) 

 glands. Tubular spinnerets absent or obscured by the excessive chitinization of the 

 pygidium. The extremity (fig. 3) bears normally four large prominent rounded 



lobes,with a small tooth-like lobe 

 on each side ; but in the older ex- 

 amples the lobes are often more 

 or less obliterated by a chitinous 

 thickening of the margin. A 

 pair of very conspicuous club- 

 shaped callosities run inwards 

 and upwards from between the 

 mesal and second lobes. There 

 are apparently no marginal 

 squames (jjlates, Corastock) ; 

 though it is possible that they may be present in the early adult ? . There are three
