rather strong, even punctuation, and anteriorly in the middle with 

 two, closely parallel, impressed lines ; the remainder of thorax 

 punctured, but less closely than dorsulum, the apex of the large 

 basal area of middle segment being almost smooth ; the middle seg- 

 ment is short and rounded ; mesosternum not at all carinated ; the 

 episternum and epimerum distinctly separated ; wings subhyaline, 

 yellowish along costa, darker in marginal cell ; submedian cell of 

 hind wings terminating beyond the origin of the cubital vein ; legs 

 stout, the tibise serrato-spinose, the spines pale ; abdomen robust, 

 more granulate than punctate, on the first segment, however, and 

 ventrally punctured ; held in certain lights the abdomen is covered 

 with golden pile, the apical segments with long, yellowish hairs; 

 first segment meeting the second broadly, the latter depressed at 

 base above, ventrally truncated at base, and w.ith a tubercle, so that 

 when viewed from the side it is angularly produced ; pygidium 

 large, well developed, aciculate, covered with golden pubescence. 

 Length 14-26 mm. 



Chapada (December). Three specimens. Seems to be very dis- 

 tinct from any Gorytes heretofore described. It seems intermediate 

 of the groups vn/staceus, nigrifrons, etc., and fuscus, robustus. It 

 agrees with the former in shape of second ventral segment, but the 

 recurrent veins are both received by the second submarginal cell. 

 From the fuscus group the former of these two characteristics will 

 separate it. Then again in the eyes, strongly converging toward 

 clypeus, it also differs. Except for the second ventral segment it is 

 not unlike G. moneduloides, but it is a much more robust insect. 

 Gorytes partitus n. sp. 



9 • — Head and abdomen, except first segment, black ; thorax, 

 first abdominal segment and legs reddish-brown ; clypeus, except 

 medially, labrum, base of mandibles, spot at base of antenna?, scape 

 beneath narrow line on pronotum, dorsulum at sides, tegula?, spot 

 beneath them, scutellum, postscutellum, large spot at each side of 

 middle segment, base of first abdominal segment, and four anterior 

 tibia? aud tarsi in part, yellow ; eyes distinctly converging beneath 

 clypeus transverse, punctured, broadly truncate ; antenna? but little 

 thickened apically, the first joint of flagellum about one-third longer 

 than second ; thorax practically impunctured ; suture between dor- 

 sulum and scutellum foveolate ; mesosternum carinated, the epi- 

 merum and episternum separated ; middle segment convex, divided 

 by a furrow its entire length, the basal area large; tibia? and tarsi
