146 Eev. T. A. Marshall's monograijh of 



tremula inhabited by that longicorn ; also bred by 

 Brischke from Larerna Ilellerella, Dup. Cocoon white, 

 pellucent, like that of A. rufipes. 



6. Ascogaster liatzehurgii, n. s. 



Niger, palpis fuscis ; trochauteribus, feinoribus tibiisque anteri- 

 oribiis, rufo-testaceis, illis basi, his apice, latins fuscis; tarsis 

 etiam fuscis. Caput rugulosuni, clypeo nou discrete, antice angu- 

 lato. Tliorax totus cum pleuris confertim reticulato rugosus ; 

 metathorax eclentatus. Alse leviter infuscatae ; areola raclialis 

 brevis, stigmati sequalis ; radii abscissa tertia regulariter curvata ; 

 nervus recurrens in areolam cubitalem primam rejectus. 



Black, palpi fuscous ; trochanters, anterior femora and tibiae, 

 rufo-testaceous, the base of the former and the apex of the latter, 

 broadly fuscous ; tarsi fuscous. Head rugulose, clypeus indiscrete, 

 angulated in front. Thorax and pleurae thickly reticulato-rugose ; 

 metathorax unarmed. Wings slightly infuscated ; radial areolet 

 short, of the same size as the stigma ; 3d abscissa of the radius 

 regularly curved ; recurrent nervure rejected. 3^ . Length, 2 ; 

 wings, 3i lin. 



Antennae somewhat longer than the body, 34-jointed, entirely 

 black. Mandibles rufous. Face covered with white pubescence ; 

 front carinated, and with the usual shallow fovea above the 

 antennae immarginate. Hind legs wholly black, except the tro- 

 chanters. Radial areolet not elongate and acuminated as in other 

 species, but the 3d abscissa of the racHus regularly curved through- 

 out its length, as in Microctonus. 



One 3' taken by Bridgman, July 3rd, at Brundall, 

 Norfolk, at the same place and time as A. elegans, Nees ; 

 but the two insects are abundantly distinct. 



7. Ascogaster variipes, Wesm. 



Ascoqaster varipes* Wesm., Nouv. Mem. Ac. Brux., 



1835, p. 234, pi. ii. (wing) ; Eeiuh., Berl. ent. 



Zeit., 1867, p. 366; Thorns., Opusc. Ent., vi., 



1874, p. 587, <? ? . 



Black, fore femora at the apex, fore tibiae entirely, middle and 



hind tibiae at the base, rufo-testaceous ; trochanters black. Meso- 



thoracic sutures obsolete. Head thickly punctate, clypeus discrete, 



■■' The Latin varus, " crooked," is confounded with varius, 

 " diversified," in too many entomological nnmes, and is likely to 

 mislead those who expect to find a meaning in descriptive epithets.
