over twice wider than long — half the length within the anterior curve ; 

 elytra flaring, venation of the reflex-veined type, the second cross 

 nervure wanting. 



Colonr : vertex yellowish olive, the tip ivory white, margined with 

 black, pronotum olive, the anterior third yellowish, elytra pale olive, a 

 large fuscous blotch back of the cross nervure between the sectors, and 

 another on the margin of the third ajMcal cell, reflexed veinlets white, 

 margined anteriorly with fuscous, all below, except tarsi and part of the 

 genitalia, black. 



Genitalia : female, ultimate ventral segment twice the length of the 

 penultimate, lateral margins strongly narrowing posteriorly, posterior 

 margin angularly excavated one-third the depth of the segment, with a 

 rounding medially cleft tooth equalling the lateral angles ; male, valve 

 triangular, the apex produced, ])lales narrow at base, nearly twice longer 

 than valve, narrowing towards the blunt, angularly divergent apices. 



Described from one female from Arizona (Kunze), one from College 

 Park, Md. (Johnson), and one male from Aid. (Heideman). This is 

 another of the reflex-veined group, and would fall between pj-odiicta and 

 imptitans ; from the former it is readily separated by its colour, and I'rom 

 the latter by the much longer vertex. 



Deltocephalus flexulosus, n. sp. 



Form of refiexics nearly with narrower vertex and elytra, resembling 

 ahbreviatus in colour and ornamentation. Light cinereous, with the 

 margins of the nervures and the m.arkings on the vertex fuscous ; face 

 black above, white below. Length, 9 4 mm., $ 3.5 mm., width 1.25 mm. 



Vertex one-third longer than pronotum, nearly that much longer 

 than its basal width, disc flat, the margins sharp; face as in reflextis ; 

 pronotum distinctly narrower than the eyes, twice wider than long ; elytra 

 longer, narrower than in i/iflatus, with a similar venation, veins on clavus 

 separate or only connected by a cross nervure. 



Colour : light cinereous washed with pale yellow, traces of pale olive 

 or fuscous lines on the pronotum ; margins and tip of vertex ivory white, 

 an orange line just inside the margin and a fuscous circle around tip ; 

 fiytra pale, the nervures creamy white with narrow fuscous margins, a 

 fuscous s])ot either side the cross nervure on the clavus, and a larger pair 

 next the first cross nervure on the corium, the apical margin and the 

 anterior margins of the reflexed veinlets fuscous ; upper half of face shin-
