detailed diagnosis in respect of the antennae, the basal joint 
of the flabellum not enfolding the following joints (although 
the apical joint enfolds the preceding ones, as in EnamillusJ. 
It also differs widely as a species from the unique Enamillus 
(E. striatus, Slip.), especially in its pronotum not being 
pilose and its elytra not regularly striate, but it is certainly 
so close structurally to Enaiinlhts that no confusion can result 
from its being assigned to that genus. Unfortunately, my 
specimen has lost its legs, though in all other respects it is in 
excellent condition. The Systdlopidex are so rare in collec- 
tions that I do not like to omit the opportunity of describing 
this one, and the species of that subtribe are, so far as known, 
such isolated forms that it is unlikely any other species ex- 
ists which would be capable of confusion with the present one 
for want of a description of the colour, etc., of its legs. 
E. sharpi, sp. nov. Testaceus, antennarum flabello, palpo- 
rum maxillariuni articulo apicali, capite postice pro- 
" noto medio et elytris rufo-piceis (pedibus exempli typici 
carentibus) ; supra sat glaber sed protliorace piloso- 
fimbriato ; subtus sat hirsutus ; capite (labro sat laevi 
excepto) crebre sat rugulose punctulato ; pronoto sub- 
nitido minus crebre minus fortiter punctulato, fortiter 
transverso, antice valde angustato, lateribus fortiter ro- 
tundatis, angulis anticis sat acutis posticis iiuUis : scu- 
tello transverso sparsim punctulato ; elytris inaequaliter sat 
crebre punctulatis, subopacis nee velutinis, striis sub- 
suturali fortiter duabus (geminatim positis) modice 
quatuor (geminatim positis) vix et tribus sublateralibus 
fortiter impressis. Long., 5^ 1. : lat., 2^ 1. 
The elytral striae are as follows : — A subsutural stria 
deeply impressed except close to the scutellum ; three pairs of 
striae (the two of each pair very close to each other) at wide 
intervals from each other and from the subsutural stria, the 
first pair obsolete in front, but moderately deep behind, the 
other two pairs scarcely distinct : three entire, fairly deep 
striae close to each other ana to the lateral margin. The 
piceous median portion of the pronotum is narrow in front 
and much dilated hind ward, so as to be of triangular form.

SERICIDES (Second subtribe of Australian Melolonihidesj. 
Regarding this subtribe I have little to add to what I 
wrote seven years ago in the memoir already referred to, 
where I discussed at some length the character that Lacordaire 
relied on as essentially distinguishing the Sericides from the 
Sericoides, and, without disputing its validity, proposed a
