other characters, which will or ought to decide the general affini- 

 ties of the species in question. If we leave Acyrusa in the neigh- 

 bourhood of Ohritmi*, how is JPJioracantha (some of the species 

 of which approach it very nearly in their characters) to be dis- 

 tinguished ? 



Igenia. 



Characteres ut in Obrio, sed coxce anticse globosse, haud eductse. 



Proposed for the reception of Ohrium ihidionoides, Pasc. (Trans. 

 Ent. Soc. ser. 2. v. p. 26). To this I would add Ohrimn dorsale, 

 Pasc. (Journ. of Entom. ii. p. 237). Between the two, but more 

 intimately allied to the latter, is the following new species (it may 

 be thought that the radical difference in the anterior coxae shows 

 that this genus has nothing whatever to do with Oirium) : — 



I&ENIA STIGMOSA. 



/. luteo-testacea ; capite, fascia lata postica et lineis duabus ante medium 

 elytrorum castaneis. 



Hab. South Australia {Mr. Odewahn). 



Yellowisli testaceous : the head, a broad band near the apex of the elytra, 

 and an oblong dash on each side between the band and the base, 

 brownish chestnut; head coarsely punctured in front, and forming 

 between the eyes longitudinal ridges ; prothorax about half as long 

 again as broad, nodose at the sides, irregularly punctured, the punc- 

 tures leaving about five smooth spaces on the disk ; scutellum trian- 

 gular ; elytra rather narrow, subseriate-punctate, the punctures coarse, 

 but becoming gradually less so posteriorly, behind the middle a broad 

 chestnut band, not touching the apex; body beneath luteous, shining; 

 band between the eyes (beneath) and last four abdominal segments 

 chestnut ; legs luteous, the tips of the tibiae and tarsi darker ; an- 

 tennae dusky luteous, the third joint longer than either the scape or 

 the fourth joint f- Length 4^ lines. 



SiSTEIUM. 

 Caput antice breve. Oculi magni, reniformes, supra modice distantes. 

 Antennce longitudine corpori sequales; articulo tertio quam scapus lon- 

 giore, mutico ; articulis ultimis vix compressis. Prothorax oblongus, 

 capite latior, lateraliter irregularis. Elytra parallela, apice rotundata. 

 Pedes mediocres^ postici longiores; tarsi breves; acetabula antica 

 cicatricosa, vix angulata. 



* Obriuni now contains only the three European species cantharinum, L., 

 hrunneum, Fab., and bicolor, Kraatz, the North- American 0. maculatum, and 

 probably a few others from the United States. 



t In /. ihidionoides it is longer than the fourth, but shorter than the scape ; 

 in /. dorsalis it is a trifle shorter than either.
