Tribe TANYMECINI Horn (1876) 

 Table of genera of Tanymedni. 



1. Thorax feebly lobed behind the eyes, and bisinuate at base; eyes transversely 



oval, pointed beneath Pachnseus Schonherr. 



2. Thorax not lobed, base truncate, eyes round or longitudinally oval, 

 a'. Anterior femora normal, tibicC simple. 



6'. Posterior cox^ moderate in size, normally separated Taitymecus Germar. 



6^. Posterior coxae small, very widely separated. 



c\ Ocular vibrissse almost obsolete Minyomerus Horn 



c^. Ocular vibrissae very evident Elissa Casey. 



c?. Anterior femora much longer and stouter tlian the others, the tibiae denticu- 

 late withm Iladromtropsis, new genus. 



Genus PACHNSEUS Schonherr (1826). 



Pachnseus Schonherr, Cure. Disp. Meth., 1826, p. 121. 



Pachneus Gemminger and Harold, Cat. Coleopt., vol. 8, 1871, p. 222'i, 



The originally designated type was ojpalus Olivier. 



Genus TANYMECUS Germar (1817). 

 Tanymecm Germar, Mag. der Ent., vol. 2, 1817, p. 341. 

 Schonherr (1826) designated the type as palliatus Fabricius. 

 Genus MINYOMERUS Horn (1876). 



Minyomerus Horn, Proc. Amer. Philos. Soc, vol. 15, 1876, p. 17. 

 Pseudelissa Casey, Ann. New York Acad. Sci., vol. 4, 1888, p. 273. 



The type of Minyomerus is hereby designated as innocuus Horn. 

 Pseudelissa is nionotjrpic, based on {cinerea Casey) =languidus Horn. 



Genus ELISSA Casey (1888). 



Elissa Casey, Ann. New York Acad. Sci., vol. 4, 1888, p. 271. 



We ma}^ hereby designate laticeps Casey as type of this genus. 



HADROMEROPSIS, new genus. 



Hadromerus Schonherr, Gen. et Sp. Cure, vol. 2, 1834, p. 125 [not Schonherr 

 1826]. 



Schonlierr's (1826) genus Hadromerus \\iiS>2LS\i^ type Sagittarius Oli- 

 vier. Schonherr made an unfortunate mistake in his second volume 

 (1834) in overturning his twice designated type of Hadromerus (1826, 

 1833) and giving the genus a new type, nohilitatus Gyllenlial. In 

 addition he described Siderodactylus wath Sagittarius as type, thus 

 making it an isogenotypic synonym of the true Hadromerus. For 

 the genus with nohilitatus as type we may take a new name, Hadro- 

 meropsis. Our opalinus Horn belongs here. 



PANDELETEINI, new tribe. 



Pachyrhjnchinae Pierce, Proc. Ent. Soc. Wash., vol. 13, 1911, p. 49. 



The separation of the anterior coxse seems to be a good character 

 for separating the Tanymecinse into tribes. The genera placed here
