114 Mr. F. 1\ Pascoe on some new or Uttle-knoton 



captures of Mr. Fry at liio, which perhaps, partly from their small 

 size, and partly from the extremely limited area which many of the 

 insects of that country affect, it is almost hopeless to expect can 

 ever be obtained except by the most indefatigable and experienced 

 collectors. The number of undescribed genera which are almost sure 

 to be found in every extra-European collection that may be foraied by 

 an accomplished naturalist, should not be overlooked by those who 

 are inclined to question the necessity of the multiplication of new 

 names. 



Pharaj) laticolUs. (PI. VIII. fig. 1.) 

 P. ovatus, fuscus, tuberculiferus, griseo-setosus ; antennis capitis latitu- 



dine sequalibus. 

 Hab. Brazil (Rio). 



Ovate, dark brown, covered with short, stiff, scale-like hairs: head 

 slightly concave above ; protliorax somewhat bilobed anteriorly, its 

 disc with four depressed tubercles ; scutellum deeply set ; elytra short, 

 convex, with about ten tubercles on the disc, the posterior being the 

 largest, the margins irregiilarly set with short stiff scales ; antennae, 

 palpi, and tarsi feiTuginous, the former about equal in length to the 

 width of the hea,d. Length 1^ line. 



Chorites [Colydiidse]. 



Head transverse, much narrower than the prothoi-ax and deeply inserted 

 in it, its supra-antennary borders slightly produced. Eyes large, and 

 very rough, from the facets being- prolonged into short spines. Antennae 

 short, slender, eleven -join ted, the first and second slightly incrassated, 

 the third longest, the remainder to the ninth gTadually decreasing in 

 length, the tenth and eleventh forming an abrupt ovate club. Maxillary 

 lobes ciliated, the external subtriangidar, the internal naiTower. Palpi 

 short, claviform; the temiinal joint of the maxiUary ovate-cylindrical, 

 of the labial ovate-oblong. Mentuni subquadrate. Labium trans- 

 verse, ciliated anteriorly. Prothorax veiy transverse, narrowed and 

 sinuated anteriorly, as broad as the elytra at the base. El}i;ra convex, 

 short, the sides gradually rounded to the apex. Legs small ; coxae, 

 especially the posterior, very remote; femora compressed; tibiae 

 slightl3^ enlarged at their extremitj-, ciliated externally, and terminated 

 by two short spiu-s ; tarsi short, slender, with long hairs beneath, the 

 basal joint very distinct. Abdominal segments gradually decreasing 

 in size. 



The widely separated posterior coxae narrow considerably the 

 number of Colydian genera with which Clwrites may be compared ; 

 at the same time, although the first abdominal segment is in every 

 way larger than the others, there is not the decided difference we 

 see in Derataphrus, Sosylus, &c. ; and if we exclude these genera,
