COLPOCHILA DECEPTOR, Sp.UOV. 



■ Elongato-ovata ; sat nitida ; brunnea vel rufotestacea, iridescens ; 

 pedibus piceis, aiitennis palpisque pallidis ; pectore

 (hoc sat brevi) confertim rugulose, prothorace minus 

 subtiliter sat crebre, elytris (his geminato-striatis) sat 

 foi-titer vix crebre, punctuhitis, pygidio obscure sat crebre 

 granulate, granulis singulis setas brevissimas singulas ferenti- 

 bus ; antennis 9-articulatis ; prothoracis basi leviter bisinuata, 

 quam margo anticus hujus dimidio latiori, angulis posticis 

 (superne visis) distinctis obtusis nullo modo productis ; 

 elytris apice suturali hand pi-oductis. 

 Mas (?) latet. 



Feminse (?) antennarum flabello stipite minus duplo breviori, 

 3-articulato, — stipitis articulis ultimis 2 intus vix dentatis.

 This species is exceedingly close to C. bella, from which it differs 

 chiefly by its more closely punctured prothorax, which is a little 

 less transverse (not quite twice as wide as long), with sides not 

 sinuate behind the middle, hind angles not acute and not in the 

 least produced (in bella these are subdentiform pointing somewhat 

 outward and hindward), and base less strongly bisinuate ; I notice 

 too that in the example before me the uppermost of the external 

 teeth on the front tibiae is very much larger than in any example 

 that I have seen of bella, and all the teeth are much less acute. 

 The pygidium too is differently sculptured, having the punctui'es 

 replaced by minute granules each bearing a very short erect seta. 

 I suppose the example before me to be a female, on account of 

 its comparatively short and stout hind tarsi. The antennae 

 scarcely differ from those of C, bella (female).

N.15. — I have received from Mr. Sloane two examples taken in 

 N.S. Wales which probably pertain to a species distinct from, but 

 very close to, C. decepto7- ; as they appear to be the same sex 

 (female) I think it better not to give them a separate name for 

 the present, but will content myself with saying that they are of
