or less sulcata, with or without a faint median carina. The 

 lateral foveolas are obsolete or distinct, elon^^ate triangular, 

 or linear, not visible from above. The Irontal costa is plain 

 or sulcate with the sides nearly straight and very moder- 

 ately divergent. The face is nearly straight or a little arcu- 

 ate, never at all sinuate. The antenna are filiform, some- 

 times depressed and acuminate at the apex. The pronotum 

 has the disk nearly plain, with the median carina cut in or 

 behind the middle. The lateral carinae are generally decid- 

 edly or strongly sinuate, rarely nearly straight and diverg- 

 ent from the front border, or irom the first and second 

 sulcus. Very rarely the\' are nearly parallel. The lateral 

 lobes of the pronotum have the anterior border decidedly 

 oblique and straight or a little arcuate, the posterior border 

 is less oblique and more or less sinuate and the lower border 

 is decidedly angulate in the middle. The mesosternal lobes 

 are separated by a space broader than long (female) or 

 about as broad as long (male), and the metasternal lobes 

 by a space not broader than long (female) or they are con- 

 tiguous (male). The tegmina and wings are well developed, 

 a little shorter or much longer than the abdomen. The 

 former are very narrow, with the scapular area not more 

 expanded in the male than in the female. The discoidal area 

 is destitute of the intercalary vein and the ulnar area in 

 the male is sometimes much widened and regularly reticulate. 

 The posterior lemora are moderately slender or rather 

 heavy. The apical spurs on the inner side of the posterior 

 femora are never very unequal. The valves of the ovipositor 

 are moderately exerted.

This is the insect perhaps better known as Stenobothrus 

 maculipennis Scud. It is ver^' variable, and a description 

 to cover all forms can not be well formulated. Head and
