SCALE-INSECTS (COCCIDAE). PART II.

Icerya sp. 



Uganda : Entebbe, 20. viii. 12, on orange (C. C. Gowdey, no. 4336). 



All the leaves submitted were heavily infested with young females. It is just 

 possible that this insect may prove to be Douglas' Icerya ( Orionia) natalensis, 

 but it will be necessary to secure old adults in order that a correct specific 

 determination may be given. Douglas unfortunately did not describe the 

 immature females and I know of no recent account of the younger stages of this 

 insect in the literature of the Coccidae. 



Aspidoproctus giganteus, sp. n. 



Female adult, when perfect, completely covered with a thin, compact coating 

 of dusky grey secretion ; the secretionary matter is, however, frequently worn 

 away, either partly or entirely so, revealing the dark castaneous chitin beneath. 

 Dorsum with a large, double, mammiform projection, which arises at the junction 

 of the abdomen with the thorax ; abdominal area with a submarginal series of 

 tubercular projections, often but faintly indicated ; margin with short, broad and 

 often bifid waxen appendages. Antennae (fig. 3a), very short, stout, being 





mt) fr.

 glands ; d, mesal compound glands ; e, circular gland ; /, spine. 



approximately of the same length as the tibia of the posterior leg, and composed 

 of 9 segments, of which the terminal one is nearly three times the length of the 

 8th ; 5th-8th inclusive, more or less bead-like ; all the segments with fine hairs. 

 Legs short and stout ; tarsus, inclusive of the claw, half the length of the tibia. 

 Mentum (fig. 3/;) monomerous and relatively very small for so large a species. 

 Immediately below the mentum are three pairs of very large glands (fig. 3c, d), 

 en cli one of the upper or proximal and the lower or distal pairs opening into a 

 large and somewhat cylindrical chamber ; the second pair (fig. 3c-,) communicates
