and rather narrow, the inner margin and apex narrowly pale and sparsely- 

 covered with short bristles. 



Described from three males and two females (No. 6ii). The 

 number of brown marks beneath and the extent of the white bands 

 above is subject to some variation. It is with pleasure that I dedi- 

 cate this large and striking- species to the well-known scientist who 

 has been instrumental in bringing to our knowledge this and many 

 other rare and interesting insects. 



14. Deltocephalus minutus n. sp. 



Al:)()ve pale greenish yellow; vertex with two oblique fulvous spots on 

 the disc; tergum and all beneath deep black. Length 2.25 mm. 



Head a little wider than the pronotum ; anterior edge well rounded. 

 Vertex almost as long as the pronotum; anterior angle obtuse, surface a little 

 sloping. Front short and broad, transversely convex, its length and breadth 

 subequal. Clypeus about two-thirds the length of the front, regularly nar- 

 rowed to the apex, margin almost rectilinear. Lorae small, extending about 

 two-thirds the length of the clypeus. Cheeks wide, strongly angled just 

 below the eyes; margin beyond the lora; broad, reaching the apex of the 

 clypeus. Anterior margin of the pronotum strongly rounded, hind margin 

 feebly, angularly, concave; sides very short; latero-posterior margins straight 

 and oblique, the angles obtuse. Scutellum small. Elytra longer than the 

 abdomen, narrow, the costal margin but feebly convex; apical areoles large. 



Color : Vertex including the fore margin to before the ocelli, yellow; 

 posterior disc with two approximate oblique fulvous spots which diverge an- 

 teriorly; apex sometimes with two minute black points. Eyes and ocelli 

 black. Face deep black; outer angles of the cheeks below the eyes, two 

 small points on the base of the clypeus, another at the outer edge of the 

 lorte, and in some examples faint indications of the transverse lines on the 

 front, yellow. Base of the rostrum pale. Antennae brown, apex of the first 

 joint pale. Pronotum pale yellow, sometimes tinged with green; anterior 

 margin slightly uneven. Elytra whitish hyaline, tinged more or less strongly 

 with greenish yellow toward the base. Nervures pale yellow. Wings hya- 

 line, feebly iridescent; nervures pale brown, inconspicuous. Legs testaceous 

 brown; femora and some dots on the jiosterior tibiae black. Abdomen black; 

 edge of the connexivum and posterior margin of the last dorsal segment 

 yellow; inner edge and apex of the plates testaceous. 



Genital pieces. — Male : Last ventral segment rather deeply concave. 

 Valve broad and short, apical margin obtusely triangular. Plates triangular, 

 their apex produced, the submargin with a few short bristles. Styles ex- 

 tended beyond the tip of the plates, toward their apex fringed with numerous 

 stout bristles. Pygofers short, below thickly covered with short white hairs, 

 above and toward the apex with stout dusky bristles. 



Descril^ed from three males (No. 610); females unknown to me. 

 This minute species bears a marked resemblance to D. melsheimerii 

 Fitch, than which it is almost one-half smaller. It still more closely 

 resembles specimens of D. minkii Fieber, collected in Quebec, and 

 kindly furnished me by M. L' Abbe Provancher. The fulvous mark- 

 ings on the vertex are variable in extent as is the number of pale 

 spots on the face.
