446 SuHarp— On New Zealand Coleoptera. 
The form is rather short, convex. The head is deflexed, the eyes moderately 
convex. The pronotum is margined at the base, sides, and front, but has no den- 
ticles or sinuation on the lateral margin The front cox are situated as near as 
possible to the front margin of the prosternum, which is not at all detlexed; they 
are moderately separated, the prosternum arched upwards behind them. The 
middle coxe also are moderately separated; the metasternum is short: the hind 
coxee are not more widely separated than the others. ‘The femora are rather 
slender, unarmed; the tibie are simple, straight externally, not mucronate at the 
apex; the third joint of the tarsus is bilobed, but it is short, and fitted rather 
closely to the preceding joint; the claws are appendiculate. 
The genus is established for the insects placed by White and Broun in 
Colaspis; but, according to the classification of Chapuis, they must not only be 
removed from Colaspis, but also from the group Colaspites, and their posi- 
tion would appear to be in the group Iphimaites. Peniticus is clearly an allied 
form, and as a genus is distinguished by the short convex form, the greater 
separation of the coxee, the excessively short metasternum, and the position of 
the front coxee, which is not quite so close to the front margin. 
ATRICHATUS (nov. gen. Euomlpinorum). 
Corpus oblongum absque pubescentia; prothoracis anguli posteriores liberi ; 
coxee posteriores magis quam anteriores et intermediz distantes. 
This is another form closely allied to Eucolaspis, but appearing to me entitled 
to generic distinction. The anterior and middle coxz are but little more sepa- 
rated than they are in Eucolaspis, but the posterior are more widely distant. 
Although very different in form to Peniticus, Atrichatus is as near to it as to 
Eucolaspis, but the front coxee are not so widely separated, and the metasternum is 
not so extremely abbreviated. Atrichatus has the antenne very widely separated, 
and the tibiz broader at the extremity, and excavate externally ; the front coxze 
are very near the margin of the prosternum, though not so excessively close as 
they are in Eucolaspis. The claws are appendiculate. 
The insect which I take for the type of this genus was found at Christchurch by Wakefield. I do 
not describe it, as I think it may probably be the Colaspis ochraceus of Broun, but figure it. (Plate 
xiu., fig. 24.) 
PILacoLasPis (noy. gen. Eumolpinorum). 
Corpus oblongum, subtiliter pubescens; coxze anteriores et intermediz satis, 
posteriores magis, distantes, anteriores bene pone prosterni marginem anteriorem 
site. 
This is allied to Eucolaspis, but presents too many points of distinction to be 
treated as a mere extension thereof. The hind coxz considerably more widely
