HORN EXPEDITION—COLEOPTERA. 
the average a little larger than that insect and a little more roughly sculptured, it 
is well to' mention the existence of a doubt as to its identity. 
Palm Creek, Paisley Bluff, Goyder River, Hermannsburg. 
CESTRINUS. 
C. piceitarsis, Hope (1). This specimen is extremely immature, and therefore 
difficult to identify ; I do not, however, see any reason to distinguish it from the 
Cestriniis that I take to be piceitarsis, Hope. 
Paisley Bluff. 
PTEROIIELiEUS. 
P. bullatus, Pasc. (1), Charlotte Waters. 
P. vicarms, Pasc. ? (1). This specimen seems to be identical with one from 
Central Australia in my collection which I have doubtfully attributed to vicarius, 
Pasc. Mr. Pascoe’s descriptions are such that it is impossible as a rule to identify 
them with any insect unless it happens to be one presenting very marked 
characters, which the present one does not. 
Painta Springs. 
P. bagoteiisis, sp. nov. (1). Sat anguste ovalis ; sat nitidus ; minus convexus ; 
piceus, antennis palpis tarsisque dilute rufis, prothorace elytrisquo ad latera et 
femoribus obscure rufis ; capite postice crebre subrugulose punctulato ; prothorace 
quam longiori (et postice quam antice) plus quam duplo latiori sparsim subobsolete 
punctulato, obsolete canaliculato, marginibus latis manifeste (pra3sertim antice) 
reflexis, angulis anticis sat productis (posticis acutis leviter retrorsum clirectis), basi 
trisinuata ; elytris sat late (sed quam prothorax et postice quam antice minus late) 
marginatis, seriatim punctulatis sed apicem versus fere Isevibus, puncturis sat 
parvis, interstitiis planis ; prosterno in medio granulato latera versus strigato ; 
mesosterno metasterno et segmento ventrali basali latera versus eranulatis : 
abdomine in medio subtiliter sparsius punctulato. Long. 7^ 1. Lat. 41 1. 
Compared with P. planus, Blessig. (which is peltoides. Mad.) this species is 
very similar in outline, except that it is less acuminate and drawn out at the apex 
of the elytra; it is also considerably more convex than that insect. The margins 
of its prothorax and elytra are extremely similar in width to those of P. plamis, 
but that of its prothorax is more evidently reflexed and its extreme border is more
