the proiiotum in front of the scutellum is very distinct in this 

 species and is more or less distinctly traceable when looked 

 foi in all the other species of Nc^io that I have examined ex- 

 cept in N . usta, Blackb., and tlie typical specimen of S . arma- 

 ticeps, Macl.

SCITON. 



The sj^ecies of this genus seem to be extremely rare in 

 collections. The following new species is in the South Aus- 

 tralian Museum. 



S. variicollis, sp. nov. Fem. Leviter ovatus; sat elongatus; 



subopacus, nonnihil pruinosus; supra glaber; subtus 



parce pilosus ; rufoferrugineus, antennarum flabello tes- 



taceo; capite confertim subtilius ruguloso, hoc inter ocu- 



los quam clypei margo anticus truncatus ut 4 ad 3 la- 



tiori ; antennis 9-articulatis, flabello quam articuli 2-6 



conjuncti breviori; prothorace quam longiori ut 7 ad 4 



latiori, antice leviter angustato, supra subtilius sat 



crebre punctulato, postice sat fortiter declivi, lateribus 



(superne visis) leviter arcuatis, angulis anticis acutis 



minus productis posticis (superne visis) obtusis, basi mar- 



ginata utrinque sinuata, scutello punctvilato longitudin- 



aliter leviter carinato; elytris geminato-striatis, intersti- 



tiis subfortiter sat crebre punctulatis (alternis angustis 



convexis) ; pygidio nitido crebre subtiliter punctulato ; 



tibiis anticis extus tridentatis; tarsorum posticorum ar- 



ticulo basali quam 2"s sat longiori, coxis posticis quam 



metasternum sat brevioribus; segmento ventrali apicali 



postice subtruncato. Long., 1^ 1.; lat., 3J 1. 



Resembles *S'. ruber, Blackb., from which it differs inter 



alia by its clypeus wider in front (in riiher the truncate front 



margin of the clypeus is very little more than half as wide as 



the interval between the eyes), its prothorax less transverse 



and less narrowed in front and strongly declivous behind, and 



the basal joint of its hind tarsi notably longer in proportion 



to the 2nd joint. Its very much larger size, as well as its 



clypeus wider in front, etc., readily distinguishes this species 



from S. paulhis, Blackb.

Byrrhomorpha. 



I have before me an undescribed species belonging to Mr. 

 Lea which is certainly a member of this genus, although its 

 inclusion therein involves the removal from the generic diag- 

 nosis of the words ''labrum supra clypeum sursum produc- 

 tum." The genus, however, is abundantly distinct on ac-
