OBSERVATIONS ON SCALE-INSECTS (COCCIDAE)— III.

large clear space in the chitin, in the region of the long outstanding hau: ; all the 

 articulations broad. Legs normal. Anal lobes (fig. 19, b) conjointly pynform in 

 outline, narrowest proximallv. Anal cleft twice the length of the lobes. Derm 

 glands (fig. 19, c) relatively large, irregularly and narrowly ovate. Margmal spines 

 (fia 19 d) more or less alternately very long and short, all divided distally and a few 

 somewhat palmate ; the longest are of exceptional length and markedly conspicuous. 

 At the angles of the anal cleft are three to four, usually three, very long bristles, the 

 longest of which is equal in length to the anal cleft. Stigmatic clefts obsolete ; spines 

 three, the central one exceptionally long. 



Length, l-5~2-2 mm. 



Female, second stage. Antennae of six segments, 'the 3rd the longest. Stigmatic 

 clefts and spines as in the adult ; marginal spines also similar, but much more %videly 

 separated. 



Fia;. 19. Lecanium setigerum, Newst., sp. n., $ ; a, antenna ; 

 b, anal lobes ; d, d, d, marginal spines. 



Uganda : Nagunga, on guava, 18.ix. 15 {C. G. Gowdey). 



A very small species, belonging apparently to the hesperidum group, but markedly 

 distinct and easily determined by the group of bristles at the angles of the anal cleft, 

 the relatively large marginal spines and the form of the anal lobes. Some of the 

 females contained embryo larvae. 



Lecanium (Eucalymnatus) chelonioides, sp. nov. 



Female, adult. Form flat ; very broadly ovate or narrowly so, and more or less 

 asymmetrical. Completely covered with a thin, glassy test, which is divided into 

 distinct, easily separable plates, corresponding exactly with the plates in the integu- 

 ment of the dorsum (fig. 20, a) ; margin of each plate with a strongly defined, narrow 

 ridge ; the flat interior generally with very faint radial and concentric striae. Colour 

 of dried specimens varying from pale to rich dark castaneous, margins paler. Young 

 adults are dusky amber brown. Dorsum, after maceration in KOH, divided mto large 

 plates (fig. 20, a) forming a more or less regular marqueterie pattern ; there are three 

 rows of these plates on either side of the median line, but the divisional sutures between
