462 Mr. F. P. Pascoe on some new or little-known 
produced ; scutellum subtriangular ; elytra lineate-punctate, the punc- 
tures small, the lines rather widely apart ; body beneath and legs black, 
shining; tarsi ferruginous. Length 5-6 lines. 
At once distinguished from P. striato-punctatus, Bois., and P. 
Kollari, de Bréme, by the broad semicircular emargination of the 
apex of the prothorax. From the former, which it more nearly re- 
sembles, it may also be known by the nearly impunctate prothorax, 
and the elytra more decidedly lineate-punctate, not irregularly punc- 
tured on the disk. Dr. Boisduval’s name is apt to mislead, as there 
are no stri. 
Pteroheleus servus. 
P. oblongus, glaber, obscure fuscus ; prothorace apice anguste sed profunde 
emarginato, in medio linea impressa ; elytris prothorace paulo angusti- 
oribus, striato-punctatis, striis approximatis. 
Hab. Victoria. 
Narrower than P. stlphoides *, De Br., with the prothorax a little wider 
than the elytra, its apex more deeply and squarely emarginate—not 
semicircular—and the narrowly impressed line in the middle more 
strongly marked ; elytra striato-punctate, the strie approximate ; body 
beneath and legs glossy chestnut-brown ; sides of the abdominal seg- 
ments wrinkled. Length 7 lines. 
Pteroheleus memnonius. 
P. oblongus, glaber, niger, subnitidus; capite angusto; oculis magnis, 
subapproximatis ; prothoracis marginibus subtiliter corrugatis ; elytris 
lineato-punctatis. 
Hab. South Australia (Adelaide). 
Oblong, glabrous, black, slightly nitid; head finely punctured, nar- 
rowed ; the eyes large and subapproximate, the distance between them 
in front being rather more than the length of their shortest diameter ; 
prothorax finely punctured, its margins minutely waved ; elytra closely 
lineate-punctate, the punctures well marked, the margins very narrow ; 
body beneath and legs black, shining; tarsi and lip with ferruginous 
hairs. Length 11 lines. 
A large species resembling P. silphoides; but the narrow head, 
large eyes, and fine waved lines on the margins of the prothorax will 
differentiate it from all its congeners. 
Pteroheleus bullatus. 
P. angusto-oblongus, rufo-brunneus vel fuscus; prothorace subtiliter 
punctato ; elytris submulticostatis, costis granulatis. 
Hab, South Australia (Queensland). 
* M. Lacordaire puts this species under Saragus; but it is winged, with the 
usual correlation of a long metasternum,
