72 Mr. F. P. Pascoe on new Genera 
Achriotypa basalis. 
A, elongata, subcylindrica, fusca, pube grisea sparse tecta; elytris 
sat disperse punctatis, margine exteriore in medio niyeis, basi 
macula nigra notatis, apicibus late emarginatis; antennis articulis 
tertio quartoque, hoc apice excepto, niveis; prothorace dense 
punctulato, margine basali nigro-binotato ; corpore infra castaneo, 
parce pubescente. Long. 43 lin. 
Hab. New South Wales (Rope’s Creek). 
Rhytiphora latifasciata. 
R. omnino nitide nigra, pube silacea interrupta vestita; capite 
antice valde transverso, fronte lata, tuberibus antenniferis remotis, 
vertice elevato, in medio postice sulcato, pube lineatim notato ; 
prothorace transverso subcylindrico, utrinque tuberculo parvo in- 
structo, supra pube vermiculatim disposita ; scutello semicirculari ; 
elytris paulo depressis, singulis lineis tribus obsoletis notatis, 
fascia lata fulvo-albida submedia, antice arcuata, postice flexuosa, 
ornatis, apicibus subtruncatis; metasterno ad latera tumido ; 
tibiis brevibus. Long. 11 lin. 
Hab. Australia (Cape York). 
An aberrant species, having a certain resemblance to Euclea 
capito. 
Penthea melanosticta. 
P. omnino dense albido-pubescens, nigro-maculata; capite antice 
transverso, tuberibus antenniferis remotis ; antennis ( @ ) corpore 
brevioribus, nigris, basi subalbidis; prothorace subtransyerso, 
cylindrico, utrinque dente parvo instructo; scutello semilunari ; 
elytris basi paulo latioribus, dorso utrinque dimidio anteriore 
leviter lineatim elevato, apicibus subemarginatis; pedibus yix 
maculatis. Long. 6 lin. 
Hab. West Australia (Nicol Bay). 
This species is allied to P. miliartia, which, with scenica, 
picta, sectator, and crassicollis, seem to constitute a group some- 
what different from the ordinary Penthee. Lacordaire (Gen. 
x. p. 560) says the genus is easily known by two tomentose 
depressions of the abdomen in both sexes; and in a note he 
adds, ‘‘No author that I know of has mentioned this cha- 
racter.” I had, however, previously called attention to it in 
a species of a closely allied genus, Symphyletes pubiventris 
(Journ. of Entom. i. p. 339), but in which the two patches 
were so close together as to cover nearly the whole of the 
segment. Subsequently I found that this character might or 
might not exist im the same species, or in either sex ; and it 
seemed to me so unsatisfactory, that, as a rule, I have ceased 
to mention if.
