The head is duller than in the race, and the sculpture stronger, the 

 spaces between the striae roughened. The scutellum is wider and less 

 convex posteriorly, and the dorsum of the epinotuni is strongly striate 

 transversely and furnished with a fairly acute triangular tooth on each 

 side (these are absent in the race).. In addition, the declivity is 

 vertical, its brow rectangular, the two faces not merging by a gradual 

 curve as in the race. Wings hyaline, nervures and stigma dark brown 

 (yellow in the race). 



$ . 4T mm. Dark brownish -black. The sculpture is stronger 

 than in the race, and the mesonotum has a very fine reticulate 

 puncturation in addition to the rugulosity, and is in consequence 

 duller. The posterior half of the 1st node is reticulate-punctate, and 

 in front is vertically truncate. The exserted hairs on the epinotuni, 

 petiole and abdomen are longer and a little more plentiful than in the 

 race. Otherwise like rufonigra.

The insects described under this name by Dr. Forel include two 

 distinct forms, one of which is a variety of Peringueyi, and the other 

 variety described hereunder, which must be attached to castanea, race 

 rufonigra, and is closely allied to var. mediorufa. For the other variety 

 a new name is required, and will be treated further on as var. angustior 

 of Peringueyi. 



5 • 3 - 7-4T mm. Reddish piceous, the petiole and thorax in parts 

 sometimes a little paler, abdomen piceous or black, legs and antennae 

 dark brown. Sides of pronotum more convex than in mediorufa, the 

 mesonotum more convex lengthwise, the declivity merging gradually 

 into the anterior part of the mesonotum. Epinotal spines less divergent 

 than in mediorufa. First segment of the petiole distinctly narrower 

 than in mediorufa, much less widened in front than in that variety, 

 and with less rounded anterior angles. Otherwise like mediorufa. 



$ . 9'5 mm. Black, flagellum, mandibles and tarsi dark reddish- 

 brown. The sculpture of the head a little finer and much closer than 

 in mediorufa. Mesonotum, excepting a narrower anterior and median 

 area which is shining, dull and coarsely rugulose-punctate. Dorsal 

 face of the 1st segment of the petiole a little shorter, the anterior 

 angles less rounded than in mediorufa. Otherwise like that variety.
