" There are two conspicuous club-shaped organs which appear like thickenings 

 of the body-wall, but which are really within the body cephalad of the mesal lobes. 

 These organs are about three times as long as the mesal lobes ; they converge 

 caudad ; and the cephalic end of each is suddenly enlarged. This species may 

 be distinguished from any other known American Coccid by the presence of these 

 organs." 



Habitat : In Durban only on the following plants : — Duranthea sp., Trichelia

122. Howardia moorsi (Doane & Ferris) (Plate xiii, fig. 132). 



Lepidosaplies moorsi, Doane & Ferris, Bull. Ent. Res., vi, pt. 4, p. 401, 1916. 



Scales of adult $ entirely covered by the outer layers of bark, very long (3-4 mm.), 

 moderately broad (0"8-l mm.), almost parallel- sided, with the hind extremity broadly 

 rounded and the anterior end tapering ; pale, translucent brown to deep chitin brown, 

 with thinner paler margins. The scale is flatly arched and looks like a low burrow. 

 It is horn-like in texture and very large in comparison to the size of the body of the 

 adult $. The whole horny scale — which is easily broken — is often completely covered 

 above by a whitish layer of waxy material, with which is incorporated fragments 

 of the loose bark of the host-plant. It is most often straight, but occasionally much 

 curved. I am uncertain as to the colour of the exuviae, as the whole character of 

 the material is indefinite and I possess only two small stems representing one 

 collection of material. These bear many specimens, as they are more or less densely 

 covered, but the scales are so inconspicuous that it is difficult to detect their 

 presence. 



Male puparium not observed. 



Second stage $ with chitinous thickenings from median lobes similar to adult. 



Body of adult $ elongate, broadest behind middle, front margin entire, broadly 

 rounded, abdominal segments not produced. The pygidium has one pair of lobes, 

 which are chitinous, with the margins very finely serrate, The other characters 

 of the pygidium as illustrated (fig. 132). Circumgenital glands in 5 groups, with 

 the median and anterior groups + united into a bow.

Remarks. This species exhibits several remarkable characters ; so much so that 

 I am by no means certain that it belongs to the genus Howardia at all. The elongate, 

 burrow-like scale is unusual, but the powerful median lobes and strong chitinous 

 projections into the pygidium are sufficient to warrant its inclusion in this 

 genus. 



Habitat : On stems of Pride of India (Lagerslroemia indica), in the Botanic Gardens, 

 Durban ; collected by A. Kelly, 31st March 1915.
