loiifi; li;iir-liko spines on each side. The anal orifice is very small, and situate close 

 to the extremity. Length, I'SO to 2 mm. ; greatest breadth, 1-50 mm. 



Halitat : on bark of Grislea tomentosa ; Madras, India. 



The insect forms shallow pits in the bark, or insinuates itself into 

 crevices or under loose pieces of the bark. It belongs to the group 

 (of which Aspidiotus articiilatiis, Morg., is the type) having a trans- 

 verse groove behind the cephalo-thorax. The present species (which 

 I have much pleasure in dedicating to Dr. F. Moore) may be readily 

 distinguished from articulatus by its greatly superior size, by the 

 proportionately narrow cephalo-thoracic segment, and by the presence 

 of two conspicuous club-shaped thickenings at the extremity of the 

 pygidium. The puparia of the two insects also show very distinct 

 characters, that of the present species being very thick and opaque, 

 while articulatus has a filmy and transparent scale. 



ASPIDIUTUS ARTOCAEPI, n. Sp. 

 Female piiparium minute, opaque, blackish, very convex, roughened with minute 

 dusty particles ; a single exposed pellicle, centrally situate, slightly raised, dark 

 brovrn with pale reddish margin, sometimes with a median whitish waxy patch. 

 Inner surface of scale shining black, with a conspicuous whitish patch at the apex. 

 Ventral scale adhering to the leaf, forming a conspicuous white scar surrounded by 

 a black ring. Diameter, 0"50 to 0-75 mm. 



No male scale observed. 



Adult ? (fig. 4) yellowish ; a deep lateral indentation and transverse groove 

 behind the cephalo thorax, which has also a shallow 

 median indentation in front. Median segments 

 broadest. Abdominal segments well defined. Py- 

 gidium (fig. 5) with eight prominent tooth-like lobes, 

 of which the median four are closer together than 

 the others ; second pair smallest. No marginal 

 . V'-V /^ squames. Three small spines on each sides, one 



between second and tliird lobes 

 one between third and fourth, and 

 one beyond. No circumgenital 

 glands. Tubular spinnerets absent 

 or obscured. There is a conspicuous 

 thickened line across tlie middle of 

 the pygidium, with two small loops 

 above, and the ends curved down- 

 wards the extremity. 



Length, about 060 mm. 



Habitat : on leaves of " Jak tree " (Artocarpics integrifolia) ; 

 Bombay, India. The small black scales are ranged closely along the 

 midrib and veins on both surfaces of the leaf. The puparium is very 

 like that of Aspidiotus personatus, and leaves a similar scar after
