clypeus blackish (fig. 179,1) 37. capnodes, new species 



Hind coxa and femur fulvous, the femur pale yellow or whitish at apex; top 

 of head with a pale yellow spot next to eye; face and clypeus entirely pale 

 yellowish or white 43 



43. Combined face and clypeus about 1.20 as high as wide in male, about 1.08

 bulging, their punctures rather small, somewhat sparser on clypeus; scu- 

 tellum laterally without white or with a very narrow, an interrupted, or 

 an obscure whitish margin; hind femur about 2.20 as long as wide in male, 

 about 2.11 as long as wide in female (fig. 195,c). 



40. postfurcalis, new species 

 Combined face and clypeus about 1.03 as high as wide, more or less flattened 

 below, especially in female, the punctures on lower part of face coarse and 

 close, on clypeus abruptly sparser; scutellum laterally with a rather wide 

 white margin, except sometimes in E. spilotus; hind femur 1.89 to 2.20 as 

 long as wide in male, about 1.60 to 1.97 as long as wide in female (figs. 

 195,d,e) 44 



44. Thoracic pleura and sterna black, without fulvous markings except at coxal 



articulations; apical angle of interantennal process of frons about 90°. 



41. spilotus, new species 

 Thoracic pleura and sterna mostly or entirely fulvous; apical angle of inter- 

 antennal process of frons about 105° 42. dorsalis Cresson 



45. Hind tibia whitish on its basal 0.15±, fulvous from thence to near its apical 



0.2 ±, the apical 0.2 ± fuscous (fig. 193, g) 26. albifrons Cresson 



Hind tibia white or whitish, its apical 0.2 to 0.4 brown or fuscous (figs. 195,f-i; 

 196,a-f) 46 



46. Median part of frons very strongly raised as a narrowly wedge-shaped area 



that ends ventrally, between antennal sockets, in a high thin ridge. 



48. cuneatus, new species 



Median part of frons weakly or strongly raised as a broadly triangular area 



that ends ventrally, just above antennal sockets, in a broad point . . 47 



47. Apical angle of interantennal process 90° to 120°; median area of frons weakly 



rasied and weakly differentiated 48 



Apical angle of interantennal process 60° to 85°; median area of frons rather 

 strongly raised and differentiated 52 



48. Mandible rectangular in outline, approximately parallel-sided from its base 



to near base of its lower tooth, then abruptly narrowed (fig. 190,m). 



47. quadradcns, new species 



Mandible triangular in outline, tapered from its base to near base of its lower 



tooth (figs. I90,i-1) 49 



49. First four segments of hind tarsus white, light brown to blackish at apex; 



hind femur not infuscate (fig. 195, h) ; white on upper margin of pronotum 



extending forward at least to epomia .... 45. denotatus, new species 



First four segments of hind tarsus uniformly white, or not distinctly darkened 



at apex; hind femur more or less infuscate at apex (figs. 195,f,g,i) . . 50 



50. Apical third of mandible turned about 25° (in male) or 40° (in female) from 



plane of its condyles, placing the lower tooth toward the mouth; yellow or 

 whitish on upper edge of pronotum extending forward at least to notaulus. 



46. ostentatus Davis
