found in our other American species of Platymetopms, and seems to 

 l)e a very distinct form. 



13. Deltocephalus coquilletti n. sp. 



Form nearly of D. debilis Uhl., but somewhat broader, with a shorter 

 vertex. Black, head and pronotum with four transverse white or fulvous 

 bands; elytra with as many oblique or transverse white lines. Length: male, 

 4 mm.; female, 5 mm. 



Head a little wider than tlie pronotum. X'ertex flat, sharply, but bluntly 

 angled before; length at the center equal to three-fifths of the width on the 

 hind margin, and three-ciuarters the length of the pronotum ; passage to the 

 front subacute. Face broad, front narrow, occupying hardly more than one- 

 half the space between the eyes, moderately narrowed toward the apex ; 

 sides constricted opposite the antennae. Ocelli situated a little less than one- 

 half way from the eye to the apex of the head. Clypeus narrow, sides straight, 

 or nearly so, apex rounded. Lorje long, about as wide as the clypeus. 

 Cheeks broad, well angled below the eyes, very narrow beyond the lorae. 

 Pronotum short and broad, almost oblong ; anterior margin feebly rounded, 

 posterior straight ; sides long, viewed from above almost straight, the angle 

 to the posterior margin well rounded ; the latero-posterior margins not dis- 

 tinct from the sides. Scutellum broad, almost as long as the pronotum, 

 closely punctured. Elytra broad, apex truncated ; longitudinal nervures 

 distinct, transverse obscured by the white lines. First apical areole of 

 the wing broad on the base. Face, legs and entire lower surface finely and 

 closely punctured. 



Color dark brown or black ; vertex, pronotum and clavus polished black; 

 scutellum dull. Anterior and posterior margins of the vertex and a trans- 

 verse band on the disc of the pronotum, obsolete before reaching the 

 sides, fulvous ; lateral and posterior margins of the pronotum broadly white; 

 m'edial line of the scutellum, two dots anteriorly on the disc, and two mar- 

 ginal ones before the apex, fulvous ; ocelli bright fulvous ; face deep black 

 with a broad transverse fulvous band on the middle, curved to correspond 

 very nearly with the superior edge. Legs, tergum and all beneath deep 

 black ; anterior and intermediate tibiae and tarsi, apex of the posterior 

 coxa- and the genitalia, brown ; outer edges of all the tibue and their spines 

 soiled white, the abdominal segments narrowly margined with the same 

 color. Antennae black; setae brown, ])ale at base. Elytra dark brown; clavus, 

 basal areole of the corium and margin of all the nervures as fir as the 

 apical areoles, black; nervures, except at the apex, white; a broad band on 

 the apex of the basal areole extended posteriorly along the inner sector, 

 another on the base of the antiapical areoles, the claval nervures broadly and 

 the apical margin narrowly, ivory-white. Wings deep smoky, hyaline; 

 iridescent: nervures, slender, fuscous. 



Genital pieces. — Male: valve broad, triangular, apex rounded; plates 

 broad, convex, together semicircular in form, fringed with soft white hairs, 

 the submargin with a row of stout bristles; on the disc, near the apex, there 

 is, in some examples, a small pale spot. 



Female. — Last ventral segment one and a half times as long as the pre- 

 ceding, narrow and compressed on the sides so as to inclose the base of 

 the pygofers, the apex feebly concave across its whole width; pygofers long
