Genus Tyromorphus, Raffray. 



Rev. d'Ent. 1883, p. 240. 



This genus is very different from Didimoprora. The head has 

 no more an antenna] tubercle : the palpi differ much — the first joint 

 is very small; the second one is slender at base and inflated at 

 the apex, which is more or less obliquely truncate; the third one 

 is rather large, but not so long as the adjoining ones, it is more or 

 less angidate in the middle inwardly; the fourth one is large, 

 ovate, more or less obliquely truncate at the base, generally 

 sulcate or at least strongly attenuate inwardly, obliquely truncate 

 outwardly at the apex, this truncature bearing the setiform 

 appendix : the intermediate trochanters are comparatively short, 

 the metasternum is broad and short; the posterior coxse very 

 distant; and the 2nd ventral segment larger than the others. 



This genus includes nitidus, Raffr., type of the genus, comes, 

 Schfs., and Tyrus spinosus and humeralis, Westw., which I do not 

 know, besides several new species. 



Here follows a synopsis of this genus : — 

 A 2. Entirely punctate. 



13 3. Head short, rounded ; three last joints of the 

 antennas hlack; 3rd joint of the maxillary palpi 



ovate, elongate humeralis, Westw. 



B 2. Head square ; antennae black, except the three 

 first joints; third joint of the maxillary palpi 



short, subtriangular lugricornis, n.sp. 



B 1. Head rather long, attenuate in front. 

 I ' '2. Antenna' bicolorous.
