says that, whereas his specimens in hothouses at Paris ex- 

 hibited dorsal carinas, those from hothouses in Italy had 

 dorsal depressions. It is clear that in this respect the insect 

 varies, and the dorsal marquetry is really the distinguishing 

 character of it. Targioni's name — L. depression — must, of 

 course, be retained, though the feature to which it refers is of 

 no value. Mr. Douglas reports the species (Ent. Mo. Mag., 

 1887, p. 28) in England on Ficus. The second stage and 

 larva have not been described hitherto. 



Lecanram longulum, Douglas ; Lecanium chirimolice, Mas- 

 kell, 1889. 



This insect occurs in the Sandwich Islands, and is there 

 apparently common ; for Mr. Koebele brought me thence 

 several plants upon which I found it plentiful — e.g., Fsidium, 

 Bambusa, Acacia, Citrus, and several unnamed. 



I mentioned in 1890 my conviction of the identity of this 

 species with mine from Fiji ; and comparison with these 

 specimens from Honolulu confirms that opinion. 



Lecanium scrobiculatum, sp. nov. Plate XIII., figs. 5-7. 



Adult female brownish-yellow, elliptical ; very convex in 

 the median region and slightly flattened towards the margins, 

 having thus a sort of dorsal "hump"; length about T V n ' 

 Epidermis rough, with a network of minute wrinkles on the 

 flatter portions, forming small cell-like divisions ; smoother 

 on the dorsal convexity, but marked there with many very 

 minute pit-like depressions. Antennae of seven joints, of 

 which the third and fourth are the longest, and about ecmal to 

 each other. Feet rather thick ; tarsus as long as the tibia ; 

 claw very small ; all the digitules appear to be very short. 

 On the margin of the body is a row of small spiny hairs, not 

 set close together. At each of the four spiracular depressions 

 of the margin is a chitinous semicircular band, which bears 

 some short club-shaped spines. Abdominal cleft small ; lobes 

 large, conical, setiferous ; anogenital ring with many hairs. 



Female of the second stage yellow, elliptical, flattish, but 

 with a raised median longitudinal ridge ; length about T V n - 

 Epidermis wrinkled as in the adult, but the pits on the median 

 region are not noticeable. Antennas of six slender joints ; the 

 third and fourth joints in the specimens observed were very 

 long and thin. Feet normal. Spiracular spines long. A row 

 of spiny hairs runs round the margin of the body. 



Larva not observed. 



Male pupa covered with a white, thin, glassy, elongated 

 test, very shiny and brittle. Many of the specimens observed 

 enclosed hymenopterous parasites, the pupas of which, showing
