clypeus are quite distinctive. In the females of this species and 

 querci the dorsum is regularly arcuated and they might with 

 perhaps equal right be placed in subgenus Cyrtolobus but they 

 are most nearly related to castanece and I prefer to place them 

 with that species. I have inornata from New York and North 

 Carolina. 



Subgenus Evashmeadea Goding. 



Length 7 mm. ; slender and depressed with the crest scarcely 

 elevated and sinuated in the middle; characteristic mark- 

 ings distinct in matured individuals; posterior process 

 of pronotum long, decurved and acute; inhabits 

 Arizona, concinnus Godg. 



Cyrtolobus (Evashmeadea) concinnus Coding. PI. 2, fig. 22. 



Larger and more elongated than van. Female: head and 

 pronotum pale yellowish coarsely punctured with brown, anter 

 ior oblique vitta not distinguished from the pale anterior sur- 

 face of the pronotum, the hind margin of which it forms; near 

 the base of the low dorsal crest it is bent at a right angle and 

 passes almost straight across the dorsal carina. Surface behind 

 this pale anterior vitta dark brown bordered with fuscous or 

 black; the median spot nearly square, whitish; posterior vitta 

 oblique and extended along the lateral margin to join the an- 

 terior vitta or pale surface. Elytra hyaline, base punctured ; 

 apex a little infuscated. Face large, even, coarsely punctured, 

 regularly rounded before; clypeus and lorae scarcely disting- 

 uished, the former forming a very small rounded angle at the 

 apex of the face, not at all incurved. Legs brown, the knees 

 and edges of the femora pale, Pronotum loDg and low, the 

 slender decurved apex almost attaining the tip of the elytra. 

 Dorsum but slightly elevated, distinctly sinuated at the median 

 spot and posterior vitta. In pale examples the markings are 

 nearly or quite absent. Male: anterior pale surface strongly 

 punctured and irrorated with brown; posterior dark portion 

 blackish, the usual markings and margins whitish. Legs black. 

 Abdomen dark brown with the narrow edge of the segments 

 pale. Length about 7 mm. I have before me two males and 

 four females from Arizona belonging to the collection of Cor-
