92 AUSTRALIAN BUG. 



Janson, n. sp. I append Mr. Janson's technical descrip- 

 tion,* and also give the following more general note of 

 appearance with which he favoured me : 



" Of our English Coccinellida the Rodolia most 

 nearly resembles Chilocorus bipustulatus : it is about the 

 same size as the common Two-spot Ladybird (Coccinella 

 bipunctata), but is of a more convex and hemispherical 

 form ; the thorax is much shorter, and has the sides 

 narrow, rounded, and bent down ; the head is short, 

 vertical, and concealed beneath the thorax ; the legs are 

 short, and flattened with the tibiae angulated and grooved 

 for the reception of the tarsi ; it is black above, with a 

 peculiar dusty or powdered appearance produced by the 

 fine short grey pubescence with which it is covered, and 

 has a large, conspicuous blood-red spot in the centre at 

 the base of the elytra ; the underside and legs are pale 

 rusty red." 0. E. J. 



A slight sketch of the maggot sent by Mr. Bairstow 

 showed it to have the somewhat elongate form common 

 to larvaa of this family, three pairs of claw-legs and jaws 

 (which it uses to good purposes), and that the sides of 

 the segments were furnished with pencils of hairs. 



The figure of the pupa- or chrysalis-case represented 

 this stage as passed in the typical manner of this family, 

 namely, that after the larva has become full-grown it 



* " Rodolia iceryee, n. sp. Almost hemispherical, a little longer than 

 broad, and slightly narrowed behind ; above very finely and closely 

 punctured, and rather densely clothed with fine grey pubescence ; shining 

 black, with a large semicircular blood-red spot at the base of the elytra, 

 enclosing the scutellum. Head flattened; inner margin of the eyes 

 straight ; antennae, palpi, and labrum, red. Thorax produced and 

 rounded posteriorly, truncate in front of the scutellum, strongly produced 

 and rounded at the sides, the lateral margin slightly reflexed, anterior 

 margin narrowly testaceous. Scutellum elongate-triangular, the apex 

 acute. Elytra impressed on each side of the scutellum, the humeral 

 callus very prominent, humeral angles somewhat produced anteriorly, 

 rounded, and slightly elevated. Under side and legs pale red, strongly 

 punctured, and with fine grey pubescence ; epipleurae strongly concave, 

 black ; tibite strongly emarginate for the reception of the tarsi, the outer 

 edge strongly but obtusely angulated and fringed with long grey hairs. 

 Length 45 millim." 'Notes on the Australian Bug in South Africa,' 

 p. 30.
