3. Lophyroides ruficollis. (Tab. III. figg. 11, c? ; 11a, antennae of 6 .) 



Niger, pronoto, mesonoto, mesopleuris tegulisque runs ; f emoribus tibiisque anterioribus sordide testaceis ; 



alis nigris, cellula cubitali secunda fere longiore quam tertia ; antennis 15-articulatis. c? . 

 Long. 9 millim.

The sutures on the vertex are wide, clearly limiting the vertex, which is raised 

 between them, and has a broad transverse furrow behind the ocelli, and a shallower 

 longitudinal one behind the transverse furrow in the middle ; a furrow, wide but not 

 deep, runs from the lower ocellus to near the base of the antennae ; the front is raised, 

 and curves down between the antennae, ending in a (comparatively) sharp point close to 

 the middle of the antennae, from which it tapers to near the base of the clypeus. The 

 apex of the clypeus is truncated ; the labrum is piceous. The wings and nervures are 

 deep black ; the second cubital cellule is a little longer than the first, and still longer 

 than the third, which is almost square ; the second recurrent nervure is received in front 

 of the third cubital. The joints of the antennae are fuscous. The scutellum is black; 

 only the upper part of the pleurae is red ; the anterior tibiae and femora are more or 

 less fuscous behind. 



4. Lophyroides godmani. 



Niger, pronoto, mesonoto, cum scutello, mesoplenris tegulisque runs ; alis fuscis, cellula cubitali tertia longiore 



quam secunda ; antennis 14-articulatis. $ . 

 Ijong. 9 millim.

The frontal sutures are flat and indistinct ; the space behind the ocelli and between 

 the sutures is not raised or clearly defined, nor is there any transverse suture behind 

 the ocelli ; the central antennal fovea is large, much longer than broad ; the front 

 between the antennae and at the end of the fovea projects. The antennae are not much 

 longer than the head and thorax, pilose ; the third joint much longer than the fourth ; 

 the last conical, and much narrower than the thirteenth. The second cubital cellule is 

 distinctly longer than the first, and shorter than the third by about one third ; the 

 fourth is a little shorter than the second and third together. The wings are darker at 

 the base ; the upper half only of the pleurae is red. 



Easily known from L. ruficollis by the red scutellum, much longer third cubital 

 cellule, interstitial second recurrent nervure, and by the vertex not being separated 

 from the rest of the head by deep furrows.
