Described from four examples from Logan Canyon, Utah, 

 collected by the writer. The blood- red markings will at once 

 separate this species from any other described. 



Neocoelidia coronata n. sp. 



9. Resembling pulchella in size and form, smaller and slenderer, 

 creamy with scarlet markings. Length 6.5 mm. 



Vertex acutely angled, the apex blunt, twice longer than its basal 

 width, disc flat, the anterior margin carinate. Angle with face much 

 more acute than in pulchella. Pronotum short, the margins parallel. 

 Elytra long, venation obscure, a single anteapical cell, apical cells long. 

 Female segment of medium length, posterior margin broadly rounding. 

 Pygofers very short. 



Color: creamy with scarlet markings, vertex lacking the customary 

 apical black spot, a broad median stripe from the apex to just before 

 the base, a marginal stripe against the eye on each side, extending half- 

 way to apex where they are joined by a transverse stripe, the marginal 

 stripe triangularly expanded opposite the eye and almost reaching 

 the median one, the whole marking on vertex suggesting a scarlet 

 crown. Pronotum with three parallel stripes connecting along the 

 anterior margin and extending across the scutellum. the median one 

 forking before the apex. Elytra creamy, a broad scarlet stripe extend- 

 ing along sutural margin, the apical cells slightly infumed. 



Described from a single example from Central America. 

 The striking pattern will at once separate this species and justi- 

 fies its description from an unique.

 Hypochrotaenia pilipes (Cresson). 



It appears from the account given by Ducke that the genus 

 Nomadosoma Rohwer, 1911, is identical with Holmberg's 

 (1886) Hypochrotaenia. The type of the former is Pasites 

 Cr., and of the latter H. parvula Holmbg. 



POLYBIAPIS gen. nov. (Nomadidae). 



Allied to Nomada, but resembling wasps of the genus 

 t'olybia; wings long, with only two submarginal cells (first 

 t. c. absent), the first s. m. fully three times as long as second, 

 receiving first r. n. a considerable distance from its end ; meta- 

 thorax long, very oblique ; maxillary palpi long and slender,
