THE SCALE INSECT GENUS ASTER OLE CANIUM 83 



Larva. — Nearly elliptical, posterior end narrowed. 



Margin: With 28 8-shaped pores, the posterior 6 pairs very slightly smaller 

 than the next 7, anterior pair slightly the largest, axes of the posterior 6 pairs 

 diagonal, of the others longitudinal ; a pair of minute setae close to each of the 

 posterior 3 pairs of pores; apparently normally 3 pairs of setae anteriorly. 



Dorsal surface : 8-shaped pores in a submedian row of 2-7 and a lateral row 

 of 9, on each half of body, posterior and anterior submedian, and the anterior ."» 

 lateral pores slightly larger than the others, all very slightly smaller than 

 posterior marginal 8-shaped pores; disk pores close to marginal 8-shaped pores 

 and a few in lateral area ; a pair of small setae anterior to anterior submedian 

 pair of pores. 



Ventral surface: Antennal setae, I, 2; IV, 1 ; V, 1 ; VI, 2 long, 2 stout, 3 fairly 

 stout, 2 slender; bases of antennae one-third length of antenna apart: beak 

 setae, 2 pairs apical, 1 pair basal ; spiracle with 1 trilocular and 1 quinquelocular 

 pore ; leg setae, coxa 4, femur 1 on inner margin near base and 1 on outer 

 margin near center, tarsus 1 each on inner and outer margins; tibia one-third 

 length of tarsus ; 10 pairs of submarginal 8-shaped pores ; apparently normally 

 9 pairs of minute submarginal setae, on abdomen and thorax, and 3 pairs of sub- 

 marginal larger setae at anterior end ; 1 pair of setae between antennae and 

 mouth parts. 



Apex of abdomen : Notch present ; setae, apical 72 ja long, interapical 9-10.8 

 fi long, dorsal 1.8-2 /j, long, inner ventral 9-10.8 /* long, outer ventral 5.4 fx long ; 

 anal ring with 6 setae about 18 n long and with an inner row of 6 and an outer 

 one of 10 or 12 pores, divided on dorsal side and tending toward division on 

 ventral side; ventral surface of apex sclerotized between inner and outer ventral 

 setae. 



Data. — Redescribed from one mounted female and one mounted 

 larva on StypheUa scoparia, Oakleigh, Victoria, Australia, A. Morri- 

 son, June 5, 1891, U. S. N. H., and unmounted material, four mounted 

 females, and eight mounted larvae on L&ucopogon frazeri, Motueka, 

 New Zealand, from G. Britain, December 19, 1937, No. 134. These 

 specimens have been identified from the description and figures given 

 by Maskell (68, pp. 224-226, pi. 16) and Morrison and Morrison (73, 

 pp. 4,-5, pis. 2, 27). Tests at hand agree with those described by 

 Maskell, including the position on the host with the anterior end of 

 the test always toward the point of leaf attachment, and the females 

 studied agree rather well with the characters given by Maskell and by 

 Morrison and Morrison. Morrison and Morrison prepared their 

 description from a single specimen labeled as being second stage, but 

 which they presumed to be an adult. Maskell described the second 

 stage but it is impossible to be certain whether he had a second-stage 

 specimen or an adult female, since he did not mention the tubular 

 ducts. No second-stage specimens being available, it cannot be de- 

 termined whether the form described by Morrison and Morrison 

 actually belonged to the second stage. They did not mention either 

 the presence, or absence of tubular ducts although they did state that 

 the presence or absence of multilocular disk pores was not determined.

(Fig. 22, A-G ; pi. 5. K) 



In 1844 (10, p. 300) Boiiche described Lecanium epicU ndri as 

 follows : 



"<$ dunkolgelb mit braunem Kopfe, die weisslichen Flflgel am Vorderrande 

 rothlich. Lange % Linie. 



"9 rundlich, flach, griinlichgelb, dor Rand mit dicbt stehenden verlangerten 

 Absonderungsfaden gefranzt. Lange V 2 Linie. 



"Wohnort auf Epidendrum cuspidatum in den Treibhausern. Das eigentlichc 

 Vaterland ist wohl Westindien.
