margins straight, transverse impressions and also the longitudinal 

 median groove feebly indicated ; scutellum triangular but very 

 small; elytra nearly twice as broad as the prothorax, striate, median 

 dorsal striae reaching short of the apex, the third, fouiih, fifth, and

Tribe POGONIDES. 



Mentum narrowly emarginate, and with a median bifid tooth ; 

 eyes moderately prominent ; head with a deep curved longitudinal 

 impression on each side ; last joint of palpi as long or very little 

 shorter than the penultimate one, which is truncate at the apex ; 

 labrum emarginate ; epistoma with a long lateral seta ; antennae 

 subfiliform with the two basal joints glabrous ; prothorax cordiform ; 

 elytra elongato-ovate or oblong with the fifth stria sinuate apically ; 

 legs moderately long, anterior tibiae deeply emarginate inwardly and 

 slightly dilated apically ; tarsi slender, claws not pectinate, the two 

 basal joints of the anterior tarsi of the male dilated and squamulose 

 underneath. 



I find it necessary to divide the two genera included in this tribe 

 into two groups, owing to the great difference in the shape of the 

 ligula and the paraglossae, and also in the structure of the anterior 



tibiae. 



Synopsis of Genera. 



Ligula unisetose at the tip which is broad and truncate ; para- 

 glossae very short ; tibise spinulose externally, anterior ones

 Prothorax trapezoid ; elytra without any well-defined striae . . Extromus. 



Ligula plurisetose, triangular at the tip which is narrow and

 frontal groove recurved behind the eyes ; intervals of elytra well
