there is another feeble elevation becoming linear in front, and on the basal portion 
some obsolete inequalities. I am acquainted only with the female. 
Christchurch, Wakefield ; Picton, Helms ; one example from each source. 
CEmona mutica, n. sp.—Angustior, ferruginea, griseo-vestita, antennis pedi- 
busque cum tarsis concoloribus; prothorace cylindrico, fere esculpturato, opaco, 
tenuiter pubescens. Long. 11 m.m. 
This is the most slender of the species, and may be readily known by the 
almost complete absence of thoracic sculpture, the surface being feebly uneven, 
with an obscure slight carination of the disc. The male has the sides of the thorax 
a little rounded, but in the female they are straight ; the former sex has the flanks 
of the pronotum punctate, and all the prosternum, except the front, similarly punc- 
tate ; the supplementary segment is like that of CE. plicicollis. 
Picton, Helms ; one pair. 
(mona debilis, n. sp.—Minor, angusta, ferruginea, griseo-vestita, antennis 
pedibusque cum tarsis concoloribus; prothorace angusto, subcylindrico, lateribus 
leniter curvatis, parce obsoleteque sculpturato, crebrius pubescente. Long. 10 m.m. 
Rather less elongate than Ci. mutica, with a less cylindric thorax, which is 
more pubescent and has some feeble asperities on the middle ; in the male sex the 
prosternum and the sides of the prothorax are punctate, but less definitely than in 
the other species of this group, and the punctuation is rendered still more indistinct 
by the pubescence. Without a careful examination these parts appear impunctate 
asin the female, but the species cannot be mistaken as belonging to the first group, 
in consequence of the small size and absence of plication on the thorax. 
Picton, Helms; one pair. 
Opuryops, White. 
Ophryops dispar, n. sp.—Elongatus, angustulus, testaceus, capite antennarum 
basi, thorace pedibusque ferrugineo-testaceis, antennis articulis tertio quarto quin- 
toque plus minusve fuscescentibus ; thorace dense subtilissime punctato punctisque 
majoribus sparsis parum conspicuis, subopaco utrinque longitudinaliter impresso, 
medio area angusta antice tenuissima polita; elytris, punctis majoribus impressis 
profundis. Long. 18 mm. Fem.(?) eadem species; prothorace nitido fortiter 
ineequaliter punctato, hic inde subtuberculato. (Plate xu, fig. 20.) 
The thorax of the male is very broad, abruptly constricted behind, covered 
with a dense porous-like punctation, here and there with larger punctures ; on each 
side there is a peculiar polished space, somewhat depressed, but terminating in 
front considerably behind the front margin in a very feeble elevation placed 
somewhat more towards the middle; the medial smooth space extends from front
