38 Mr. G. R. Waterhouse on Coleopterous Insects 



Amongst the numerous genera of Anthribidm defined by Schon- 

 herr, I have found none presenting the combination of characters 

 which are above pointed out. Ormiscus approaches most nearly 

 perhaps to Arceocerus, but may be distinguished by the diiferent 

 form of the eyes, which have the long diameter considerably 

 greater than the transverse, and are much narrower in front than 

 behind ; the position of the antennse is also different, and the 

 form of the joints, which are shorter, and especially the form of 

 the club, which is considerably shorter, and has not the joints 

 distinctly separated. 



The seneous tint of the elytra is only seen in parts where the 

 pubescence has apparently been rubbed ofi" : at the base of each 

 elytron near the scutellum is a slight hump, which, wanting the 

 pubescence, always presents a dark hue ; on the outer side of this 

 is an oblong patch of a pale yellowish colour, and this is not due 

 to the colour of the pubescence only, for the elytron itself ap- 

 pears to be pale at this part : in the middle is a broad brownish 

 band, which as it parts from the suture to the outer margin 

 slightly descends : on the outer margin is a broad dusky patch, 

 and there is a brownish heart-shaped spot on the suture, about 

 midway between the central fascia and the apex of the elytra ; 

 the tibiae are somewhat dusky at the apex. 



Mr. Darwin found this insect amongst others when sweeping 

 the herbage in the high central parts of Charles' Island, in the 

 month of October, 



Family OTIOKHYNCHIDiE. 



Otiorhynchus cuneiformis . Ot. ater, fusco-cinereo-squamosus, setis 

 brevibus adspersis ; antennis pedibusque piceis. 



Caput breve subconvexum, fronte longitudinaliter rugosa ; oculi fere 

 globosi : rostrum capite vix longius sed angustius, apice modice 

 dilatatum, supra fere planum longitudinaliter rugosum. Antennae 

 mediocres, funiculo articulls prime et secundo subsequaHbus ; 

 clava breviter ovata, apice acuminata. Thorax seque longus ac 

 latus, subcylindricus, apice truncatus, angustior, lateribus pone 

 medium parum ampliatis ; basi leviter bisinuatus ; supra rugosus. 

 Scutellum apice rotundatum. Elytra oblongo-subovata, antice tho- 

 racis basi haud latiora, supra convexa, lateribus pone medium am- 

 pliata, apicem versus subacuminata, ad apieem rotundata ; rude 

 punctate- striata, interstitiis parum elevatis impunctatis, seriatim 

 setesis. Pedes mediocres. — Long. corp. 2 J lin. ; lat. 1 J lin. 



This insect is so thickly clothed with mud-coloured scales that 

 it is difficult to see the sculpturing. It is considerably smaller 

 than the Otiorhynchus raucus, and the elytra being broadest 

 rather behind the middle, the thorax but little rounded at the 

 gides, and narrower in front than behind, where it is equal in 

 width to the base of the elytra, gives to the general outhne ^
