GOEYTES. 83 



furrow distinct, the clypeus hardly so convex (its colour not yellow, the red extending 

 to the antennae), the metanotum not black, the furrows on the median segment deeper 

 and the central one complete, the petiole narrower, longer, and more depressed and 

 narrower at the base (the basal part forming a distinct neck clearly separated from the 

 rest), and the abdomen differently coloured. In G. alticola the second cubital cellule 

 is fully three-fourths the length of the third, and not narrowed almost to a point 

 as ya. G. fuscipennis.

Amongst the specimens of Gorytes captured by Mr. Smith at Chilpancingo there are 

 some very similar in general coloration and form to the preceding species, but apparently 

 distinct from it. In these examples, which I have separated under the above name, 

 the clypeus and cheeks want the dense silvery pile of G. alticola ; the clypeus is black, 

 with a yellow mark in the middle, and is sparsely covered with large punctures and not 

 nearly so convex ; the antennse are more suddenly thickened at the apex, and are red, 

 with the apical four or five joints black, the third joint also being longer in proportion 

 to the fourth and distinctly more elongate than the first ; the frontal furrow is narrow 

 but distinct ; the apical two furrows on the metapleurae are deeper and wider (being 

 fully twice the width of those of G. alticola) ; the furrows bounding the basal area of 

 the median segment are wider and crenulated, the central one being wider, deeper, and 

 complete ; the petiole has its basal two-thirds black, the black followed by a reddish 

 mark, the apex being broadly yellow ; the second segment is black at the base, yellow 

 at the apex, reddish in the middle ; the third black at the apex, broadly yellow in the 

 middle; the other segments for the greater part yellow; the apical segment rufous, 

 striolated. 



The male differs from the same sex of G. alticola in the same points as does the 

 female. The wings are deeper in tint and of a more violet colour than in the female. 



The abdomen and median segment are neither punctured nor aciculated ; the legs 

 moderately spined. I am almost sure that the suture at the base of the scutellum is 

 foveolate ; but as in all the specimens the pin goes through it, I can only see it at 

 the sides.
