290 THE CANAt)IAN ENTOMOLOGIST. 



faintly edged with reddish. Veins of wings, except second sector, very 

 distinct and brownish. Last ventral segment very long, white, hind mar- 

 gin evenly rounded. 



Male. — Length 5.5 mm. While slightly shorter, the male is not 

 narrower, and this makes it appear more robust than the female. The 

 reddish borders are more prominent, and the veins of the elytra are con- 

 spicuously brown, the latter being a very rare character in this genus. 

 The valves are once and a half as long as wide at base, the sides evenly 

 oblique to the acute tip, scarcely incurved. 



There are several females in my collection from Prescott, Ariz. 

 (Ivunze), and in the National Museum a male from Texas, and a female 

 from Marble Valley, Cal. (Koebele). 



Neocoelidea riibrolineata, n. sp. — Size and form of obscura, to which 

 it is closely related. The two parallel white lines on the vertex, pronotum 

 and scutel, are very distinct. Vertex obtuse, but rather strongly pro- 

 duced, its apex without a black spot. Colour above shading into reddish 

 on the vertex, where it contrasts strongly with the white lines, giving the 

 vertex the appearance of being rubrolineate. Inner margin of elytra 

 somewhat darker. Wings with all the veins whitish. 



Male. — Slightly smaller than the female, and brighter coloured. 

 Valves large, long, parallel-sided, tumid, and apex bluntly rounded. 



Described from one male and five females in the Herbert H. Smith 

 collection, taken at Corumba and Chapada, Brazil, in March, April, May. 



Neocoelidea pallida, n.'=>\). — Female. Length 5 mm. Vertex strongly 

 produced and subacute. Colour very pale faded yellowish throughout, 

 the elytra subhyaline. Veins of wings, except second sector basally, dis- 

 tinct and brownish. Last ventral segment long, subtruncate. Male 

 somewhat smaller, valves as in liiieata. 



This species was abundant near Tucson, Ariz,, in May and June 

 (Kunze). Prof. Morse also found it at Palm Springs, Cal., on July 12th. 

 This small weak form seems to be common in the South-west. It has a 

 singular lack of salient characters. It can be readily separated from the 

 other species by its size, lack of markings, and form of vertex. 



Neocoelidea jnodesta, n. sp. — Female. Length 7 mm. Large and 

 robust, but with the usual elongate elytra. Pale sordid yellowish through- 

 out, the elytra subhyaline, the vertex with a small black spot at apex. 

 The last ventral segment is twice the length of the preceding, and very 

 broadly notched to half its length.
