Subgenus lowanus nov. 



Resembling Phlepsius but with head much narrower than pronotum 

 vertex narrow, disc flat, front long and narrow, but slightly widening 

 above. Pronotum large, pushed forward between the eyes, the lateral 

 margins long and strongly oblique. Elytra very long and narrow, over 

 one-third their length beyond clavus; central apical cell long curved, 

 narrow at base. Surface of elytra regularly inscribed with vermiculate 

 lines. 



Type of the subgenus Phlepsius {lowanus) handlirschi, n. sp. 



This subgenus is remarkably distinct in the narrow head, 

 front, and extraordinarily long elytra. It will probably be given 

 generic rank later. Phlepsius majestus Osborn and Ball, which 

 occurs in the central and southern United States, also belongs 

 to this group. This species, together with the three following, 

 form a striking series of large, showy forms that at first sight 

 are often mistaken for tawny members of the genus Gypona. 



Key to the Species of Iowanus. 



a. Vertex flat, the light margin narrow 1. elongatus n. sp. 



aa. Vertex convex, the light margin broad, 

 b. Tawny, length S}-^ mm. or over. 



c. Female segment with a broad, short notch without teeth. 



2. hebraeus n. sp. 

 cc. Female segment with a deep narrow median slit with marginal teeth. 



3. handlirschi n. sp. 

 bb. Grayish or cinereous; length 7.5 mm. or less; female segment with a triangu- 

 lar notch and prominent teeth 4. spatulatus V. D. 



Phlepsius {lowanus) elongatus n. sp. (Fig. la and b). 



Resembling majestus but narrower with a longer, flatter vertex and 

 a long acuminate female segment. Length of female, 10 mm. Vertex 

 transversally depressed, nearly flat on anterior half, acutely angled 

 with the long narrow front, one-third longer on iniddle than against eye, 

 half wider than long. Pronotum much wider than vertex, the outer 

 angles prominent. Elytra very long and narrow. 



Color. Vertex pale testaceous; the anterior third black except for 

 a narrow light margin and a median line ; a spot against either eye near 

 the base and an irregular band on middle brownish or fuscous. Front 

 pale with fuscous arcs, the upper pair very distinct and margining the 

 vertex, below they coalesce into an irregular spot on the disc. Pro- 

 notum pale, irregularly mottled with brown, three fairly definite fuscous 

 spots on the anterior sub-margin behind each eye. Scutellum fulvous 

 with six light points. Elytra pale, fulvous, uniformly inscribed with 

 testaceous. 



Genitalia. Female segment continuing full width as long as the 

 penultimate, then tapering into a long, slender point extending almost 

 to apex of pygofers.
