162 Psyche [Oct.-Dec. 



much longer than in E. maxillosus; on the radial cell it is slightly 

 shorter than high and about the length of the second cubital cell 

 on the cubitus, 



Punctation mainly as in E. maxillosus. The clypeus, however, 

 is not dull and feebly shagreened as in that species, but shiny, 

 varnished, with hardly any sculpture that can be discerned with 

 a hand lens, except for a very few, scattered, minute dots toward 

 the sides. The thorax is also somewhat more finely sculptured 

 than in E. maxillosus. Pubescence a little more abundant than 

 in that species, especially on the under side of the abdominal 

 petiole. 



Black, almndantly marked with chrome-orange (nearest orange 

 rufous of Ridg"way's color nomenclature). Head almost entirely 

 chrome-orange, with the exception of the inferior margins of the 

 eyes at the extreme base of the mandibles, the posterior half of the 

 temples, the occiput, the vertex, and the emargination of the eyes, 

 which are black. Antenna3 orange-yellow, somewhat darkened 

 above. Thorax chrome-orange; mesonotum l)lack, except for a 

 narrow, comma-shaped orange spot placed on each side of the 

 iniddle line, close to the pronotum; most of the thoracic sutures 

 more or less tinged with black. Legs chrome-orange. Abdominal 

 petiole chrome-orange, except at its base, which is black. Ee- 

 mainder of the abdomen velvety pitch-black, except its last sternite, 

 which is more or less ferruginous. Wings almost uniformly smoky, 

 "with a strong purplish effulgence. 



Male. Length (head+ thorax -[-tergites 1+2) 23 mm. 



Differs from the female only in the secondary sexual characters. 

 Clypeus much higher than broad, of a very peculiar shape (Fig. 

 la) : its basal portion is nearly rectangular and somewhat longer 

 than its apical, free part ; the latter forms a rectangular, projecting 

 plate, abruptly narrowed from the basal portion and slightly wid- 

 ened at its feebly convex or nearly straight, apical margin; the 

 lateral angles of the apical margin are blunt but prominent, bear- 

 ing short, raised ridges. The inner margin of the mandibles has, 

 near its base, a strongly raised, somewhat tuberculate fold. An- 

 tennae (Fig. 'i-d) much as in the male of E. maxillosus; their last, 

 hook-like Joint intermediate in shape between that of E. lepeleterii 

 .and E. caffer, being long, almost uniformly thick for the greater
