EUPARIUS LUGUBRIS Olivier 



Macrocephalus lugubris Olivier, Entomologie, 1795, vol. 4, no. 80, p. 13. 



In fungi growing on old logs in District of Columbia (Ulke, 1902, 

 p. 55). Occurs in the Atlantic States, abundant southwardly and 

 as far west as northeast Texas. 



EUPARIUS MAEMOREUS Olivier 



MacrocepJialus marmoreus Olivier, Entomologie, 1795, vol. 4, no. 80, p. 12. 



Breeds in white fungus on dead trees. Specimens of fungus were 

 collected at Tallulah, La., July 15, 1909, from which adults emerged 

 November 20, 1909. The species has been found on dead oak (Beu- 

 tenmiiller, 1890) ; feeding on white fungus covering base of a live 

 water oak {Quercus phellos) at Logansport, La. (Pierce, 1907, Neb» 

 Hort. Soc, p. 295) ; in tree fungus at Victoria, Tex., November 15 

 (J. D. Mitchell) ; at light, Dallas, Tex., May 27, 1905 (C. R. Jones). 

 Abundant in the Atlantic States. (See figs. 66, 67.) 



BRACHYTARSINI, NEW tribe 



The oldest generic name in the group is Amhlycerus Thunberg ^ ^ 

 (1815), which is excluded by Bridwell in footnote 7. 



TABLE OF GENBEA BRACHTTAESINI 



1. Thoracic carina not extending forvs^ard on sides Anthribulus LeConte. 



Thoracic carina extending forward on sides 2. 



2. Posterior angles of thorax salient and acuminate; eyes usually very 



prominent y S 



Posterior angles of thorax rectangular; eyes moderately or hardly 

 prominent 4. 



3. Lateral carina complete, very salient Pseudobrachytarsus, new genus. 



Lateral carina prominent in posterior half only Brachytarsus Schonherr. 



4. Lateral carina complete Araeoderes SchaefEer. 



Lateral carina extending only part way Brachytarsoides, new genus. 



This tabulation sets off the two predaceous genera PseudohracJiy- 

 tarsus and Brachytarsus from the vegetarian genera. 



The type species of Pseudobrachytarsus^ A. fasciatus Forester 

 {scabrosus Paykull), is European and lives as a larva on Coccidae 

 and transforms under the dried shell of Lecanmm genevense Tar-

^ It is impossible to accept the designation by Crotch (1870) of Amhlycerus nehulosus 

 Thunberg 1815 as genotype of Amhlycerus because of insufficient bibliographical indication 

 to determine the identity of that species which is not described in the original reference 

 and might refer to Anthrilus nehulosus Forster (1771), Bruchus nehulosus Olivier (1795), 

 or MacrocepJialus nehulosus Olivier (1795). I hereby designate as genotype of Amhly- 

 cerus Thunberg (1815) (not Raffray 1895) Bruchus rohmiae Fabricius (1781) =/Sper- 

 mophagtis rohiwae Gyllenhal (1833) (excluding description). This species is not appar- 

 ently congeneric with Spermophagus titvviUtius Boheman (1833), genotype of Sper- 

 mophagus Schonherr (1833). — J. C. Bridwell.
