Genus 41. CYRTON*. 



Palpi maxillares robusti, inerassati, art. penidtimo dilatato. 



Palpi labiales subeglindrici. 



Antennae robustte, breves, sxibdilatatce. 



Oculi laterales, magni, ovules. 



Caput hand antice productum, depression. 



TnoRAX late transversus, Icevis, impubeseens. 



Elytra robusta, brevia, subrotundata, depressa, striato-pnncta'a 

 (punctis ad apieem penitus obsoletis), glabra. 



Pedes sat robusti, femoribus tibiisque posticis leviter prodwtis, femori- 

 bus apieem elgtrorum attingentibus ; tibiis posticis rectis, longi- 

 tudinal iter marginatis, inarmatis. 



Labrum short, subrotmidate, not medially subsinuate. 



Maxillary pedpi (Tab. IX. fig. 5 m) robust, incrassated ; the first 

 joint minute and quadrate ; the second elongate and apically sub- 

 dilated ; the third as long as, and twice the breadth of the second, 

 globose ; the apical joint is broad and much depressed. 



Labial palpi (Tab. IX. fig. 5?i) more attenuate than the maxil- 

 lary, and subcylindrical, the second and third joints being nearly 

 equal in length. 



Antennas robust, short, with a tendency to dilatation ; approxi- 

 mate, situated between (not below) the eyes; the basal joint is 

 shorter relatively than in the preceding genus, Sparnus, but more 

 elongate than the second joint ; the second is short and ovate ; the 

 third is attenuate, and of equal length with the first ; the fourth is 

 hardly longer than the second ; the rest of the joints arc robust and 

 subequal in length.
