on the Genus Myllocna. 37 



I have not lieen able to verify the syiionymus marked ? , and 

 very much doubt whether any of them except " grandicollis^^ 

 refer to the species to which they are assigned in the Catalogue 

 of H. H. Stein and Weise ; ^'■gracilis, Heer" and " rubesccns, Rey" 

 probably refer to ''J/. Gnvca; " elongata, Kr." and ^'incisa, Key" 

 are more likely to refer to "J/, elongata " than to " M. gracili- 



coimis.''^ 



Myllama duhia, Grav. 



L.c. H-lf lin. = 3-3"50 mm. Fuscous black, clothed with 

 a fuscous pubescence, rather coarsely tuberculate, widest at tlie 

 apex of the elytra ; head acutely attenuated in front, mouth 

 yellow, thorax -widest at the base ; elytra as long and rather 

 wider than the thorax ; abdomen as long as the anterior parts 

 of the body united, conic, acutely attenuated towards the apex, 

 penultimate segment edged with white, apical segment pale ; 

 legs and antenna? pitchy-testaceous. 



Differs from the rest of the genus in its larger size, much 

 broader thorax and elytra, and in the much greater dilatation of 

 the base of the thorax. 



This species is not so generally distributed as the following. 



]\[yU(vna intermedia. Er. 



L.c. 1-1^ lin. = 2-2-50 mm. Fuscous black, clothed with 

 a verv short fiiscous pubescence, closely and finely tuberculate ; 

 head much attenuated in front, mouth yellow ; thorax slightly 

 dilated at the base ; elytra scarcely wider than the thorax ; 

 abdomen scarcely as long as the anterior parts of the body, conic, 

 acutely attenuated towards the apex, apical segment and postei-ior 

 half of the penultimate pale, edge of the penultimate segment 

 white ; legs and antennae pitchy-testaceous. 



Differs from M. dubia in its smaller size, narrow form, less 

 dilatation of the base of the thorax, paler apex of the abdomen, 

 and finer sculpture. 



This is perhaps the most common of all the Myllagna?, and is 

 \o be found in any marshy place.
