 61; width, 58; height of eyes, 27; malar space, 29; width between 

 eyes, 32; width at bottom of head, 19; all these taken from an aver- 

 age size specimen; interantennal plates usually distinct, triangular 

 in fonn, and separated by a more or less developed groove, which is 

 generally triangular in shape; height and distinctness of the plates 

 varying considerably in a large series of specimens; ridges bordering 

 the antennal fossae distinct and strongly arched opposite the lower 

 border of the median ocellus, continuous to the lateral ocelli; profile 

 nearly straight, very slightly concave from the apex of the clypeus 

 to the lower end of the flattened area; the whole face in section 

 strongly arched transversely along the median line; the flattened 

 area varying greatly in extent, and sometimes hardly evident, its 

 median groove also varying in depth and length; face on flattened 

 area sparsely and not heavily punctured, sides, lower end, and malar 

 spaces higlily shining and at most very sparsely punctate and hairy; 

 head red, mouth parts and a portion of the cheeks black; eyes me- 

 dium in size, usually dark; ocelli variable in color, arranged in a tri- 

 angle with the lateral ocelli nearer to the median ocellus than to each 

 other; antennae 35-36 segmented (from 20 specimens), black, except 

 that the lower part of the scape up to four-fifths of it may be red like 

 the head, leaving only an apical black band; scape not particularly
