344 HYMENOPTEBA. 



22. Iphiaulax godmani. (Tab. XIV. fig. 7, 2 .) 



Ferrugineus; antennis, capite, pedibus anterioribus, tibiis tarsisque posticis, nigris; alia nigris, stigmate 



ocbreo. $ . 

 Long. 12 millim. ; terebra 6*5 millim. 



Hah. Panama, Bugaba {Champion). 



Antennae stout, longer than the body, microscopically pilose ; third joint distinctly 

 longer than the fourth. Head densely pilose, finely rugose in front ; vertex opaque, 

 aciculate ; a furrow, broadest at the base, leads down from the vertex. Thorax shining ; 

 metapleurse punctured. Petiole deeply depressed at the base ; the inner furrow very 

 broad and deep, shorter than the outer one, the space between them in the form of 

 a sharp ridge. Second segment with an oblique depression on each side ; down the 

 centre is a smooth, shining, raised field, ending gradually in a sharp point not far 

 from the suturiform articulation, the space on each side of it being rough. Suturiform 

 articulation wide, longitudinally striated, except the lower bifurcation ; the other groove 

 much narrower. 



Differs from /. calalerensis in being longer and broader; the furrow on the front 

 much broader and deeper, especially at the base ; the wings much blacker in tint, with 

 the costa entirely black ; the abdomen broader ; the head broader ; and the colour of 

 the body of a much deeper ferruginous tint. 



b. Thorax for the greater part Mack. (Species 23.) 



23. Iphiaulax rufo-plagiatus. 



Niger, maeulis mesonoti, linea laete metanoti abdomineque, rufis ; pedibus nigris ; alis nigris, stigmate ochreo. $ . 

 Long. 11 millim. ; terebra 6 millim. 



Hab. Guatemala, San Geronimo (Champion). 



Antennae stout, shorter than the body, almost bare. Head below the antennae and 

 laterally densely covered with pale hair ; the face finely punctured ; frontal furrow wide, 

 moderately deep. Abdomen about one fourth longer than the thorax, not bulging out 

 in the centre. Petiole curved, deeply excavated at the base ; the inner furrow very wide, 

 impunctate, and without carinae, the outer one narrow, placed under the keel. The area 

 in the second segment nearly reaches, and becomes gradually narrowed, to the apex, and 

 is bordered by a depression ; this latter is coarsely, transversely striated, and united with 

 the lateral depression, which is deep, oblique, and not striated. Suturiform articulation 

 finely striated, except at the apices of the lateral branches. The furrow on the third 

 segment is finely striated. The stigma is ochreous, except at the extreme apex ; there 

 is a hyaline stripe in the first cubital nervure ; the cubital nervure is scarcely curved at 

 the base ; the recurrent nervure is received in front of the first transverse cubital nervure ; 

 the second cellule is shorter than the third. There is a small red mark on each side of 

 the mesonotum ; the line on the metanotum is broad .and placed in the middle ; the 

 apex of the abdomen inclines to blackish.
