Lygeus divisus, Walk. Cat. Het. v. p. 62, n. 138 (1872). 
The Fabrician type is in the Banksian collection contained

Lygeus mactans. 
Lygeus mactans, Stal, Berlin. ent. Zeit. x. p. 162 (1868). 
Lygeus ruficeps, Waik,. Cat. Het. v. p. 63, n. 139 (1872). 
Walker writes of his L. ruficeps :— The entirely red head 
of this species and the red spot on each side of the prothorax 
distinguish it from 1. mactans.” All the six specimens, 
however, which he had before him when he wrote his descrip- 
tion exhibit the apex of the central lobe to the head as black 
or fuscous, and there is also the black spot at inner margins 
of eyes, as described by Stal. ‘The red spot of Walker “ on 
each side of the hind border” of pronotum would have been 
better described as occupying the posterior lateral margins, 
and thus equal the “Jlateribus thoracis pone medium” of 
Stal. 
Lygeus Bettoni, sp. n. 
Pale ochraceous; antenne, legs, apex of head, eyes and 
oblique basal area on each side of head behind eyes, pronotum 
with the anterior area and two large discal spots not reaching 
posterior margin, connected anteriorly and with the anterior 
area, and also connected with the lateral margins by a short 
transverse fascia, scutellum (excluding apex), about apical 
half of clavus and outer claval margin, lateral margins of 
corium (not reaching apex) emitting a short central transverse 
fascia extending about half across the corium, black. Ster- 
num black, its segmental margins and the lateral margins of 
meso- and metasternum cretaceous white, with three large 
segmental spots on each side and the posterior lateral angles 
of prosternum pale ochraceous. Abdomen beneath reddish 
ochraceous, with its apex black. 
Pronotum coarsely punctate, principally on the black 
markings, and with an oblique transverse incision on each 
side of anterior area.
