378 COLEOPTERA 



elevated, and the spaces between it and the side margins are concave, 

 these hollowed portions are coarsely sculptured, with rugose transverse 

 elevated interstices; the disc is more closely but less regularly punctured 

 than the thorax, and shows indications of nine indistinct costse ; their 

 colour is obscure-piceous, with slightly reddened margins, but these are 

 paler than those of the thorax ; the punctures have the appearance of 

 being minutely pubescent. The prosternum is strongly punctured and 

 rugose, the abdomen is punctulate, with many abbreviated longitudinal 

 irregularly elevated lines, and it, as well as the whole under-side of the 

 body, is more or less pubescent. The femora are punctulate and pubes- 

 cent ; the tibia are coarsely sculptured, and they, as well as the tarsi, 

 bear many short yellow bristles. Antenna obscure ferruginous, finely 

 pubescent and bearing many rather long pale yellow hairs. Anterior 

 tibiae obliquely truncated and sub-dentate outwardly at apex. 



Length, 6J lines ; breadth, 3^. 



I have named this species in honour of Mr. J. Buchanan, F.L.S., 

 who found two specimens at Wellington. 



678. 0. huttoni, Sharp; Ent. Mon. Mag., August, 1878, /. 51. 

 Picea, antennis pedibusque rufis vel piceo-rufis ; prothorace nitido, 

 crebrius minus fortiter (disco parcius et subtiliter) punctate, lateribus 

 rotundatis, basin versus angustatis, ad angulos posteriores acutos haud 

 explanatis ; elytris subopacis, crebrius irregulariter punctatis, longitudi- 

 naliter subsulcatis. 



Long., 10-12 mm. ; lat, 5-6 mm. 



The antenna are short and are reddish in colour, with the third and 

 one or two following joints generally more obscure, the ninth and tenth 

 joints are decidedly shorter than broad ; the thorax is strongly trans- 

 verse, with the sides rounded, and the base a little sinuate on each side, 

 so that the hind angles are decidedly acute. 



The male at first sight seems to exactly resemble the female, but a 

 careful examination shows some constant though inconspicuous charac- 

 ters to distinguish it ; the front tibise along their inner and hinder edge 

 bear a dense very short pubescence ; the intermediate tibiae are clothed 

 in a similar but more conspicuous manner, and are not at all incurved 

 at their extremity. 



The species can only be confounded with the variable C. elongata, 

 but it is undoubtedly distinct. Mr. F. Bates, to whom we are indebted 

 for the most of our knowledge of the species of this difficult genus, 

 agrees with me on this point, and as he has been kind enough to point 

 out the characters by which it differs primo visu, I quote here his 

 remarks in a letter to me. He says : " On first looking at the Cilibe I 

 judged it to be elongata (the form phosphugoides, White) ; on compa- 

 rison, however, with a numerous series of that species, I find it to be 

 distinct. Your species has the prothorax relatively broader, distinctly 

 more rounded at the sides, and contracted at the base, the punctation 

 at the sides more open, the elytra not opaque, and with but very few of 

 the small, shining, black granules which stud the surface in elongata; 

 the two costiform elevations down the middle of each elytron are in. 

 your species obsolete."
