Hilda breviceps Stal. 



Color. — Upper part of face and narrow margin of vertex black ; 

 remainder of head stramineous ; below stramineous ; femora api- 

 cally, tibiae and tarsi, darker; sides of venter pale green. Pro- 

 notum green, becoming brownish posteriorly, the submargin 

 narrowly black, the margin white, and the anterior margin may 

 also be more or less narrowly whitish. Scutellum green, nar- 

 rowly black-margined posteriorly. Tegmina clear brown, with 4 

 paler areas, the darker areas blackish edged near costa, . the 

 blackish edges in every case flanked by small, elongate, shining 

 white calloused stripes; a white calloused stripe in the clavus, 

 another between this and the base of the tegmina on claval suture,- 

 and a third along the anal margin. Distad of the white stripe on 

 disk of clavus is a commissural green spot ; a minute white dash 

 occurs on the inner apical margin (Plate I, fig. 1). In the male 

 all of the greens and browns are darkened, becoming almost black, 

 bringing the white markings out in strong relief. All below, and 

 sometimes portions above, more or less covered with a pulverulent 

 white wax. 



General proportions of body as in Hilda inusta Mel. Width 

 of the vertex (Plate I, fig. 2) somewhat more than twice the 

 length, the fore margin broadly and evenly rounded, and the 

 surface minutely rugulose. Width of pronotum slightly more 

 than three and one half times the length, the hind margin nearly 

 straight, the surface, as also that of scutellum, with sparse and 

 very minute setigerous punctures. Scutellum one half longer 

 than vertex and pronotum together. Upper margin of head, as 

 seen from side (Plate I, fig. 3), irregularly curved. Face deeply 

 concave above the central umbo. Ocellus touching eye. Last 

 antennal joint of great size, the length two and one half times the 

 width, tapering to the tip, which reaches the upper margin of 

 the eyes. Form of face shown in Plate I, fig. 4 ; female genitalia 

 in Plate I, fig. 6 ; male genitalia in Plate I, fig. 5. Wing venation 

 as in text fig. 1. Tegmina very brittle coriaceous, venation 

 indistinct, the general surface convex, but sharply and deeply 

 grooved along the claval suture. Length of female, 5 milli- 

 meters, of male, 4.25. 



Egg. — The egg (Plate I, fig. 10) is deposited in masses of from 

 10 to 100 or more, neatly arranged side by side in adjoining rows 

 on the surface of a fruit or leaf. They measure 0.3 by 0.65 milli- 

 meter, and are pale yellow, the surface covered with sharply 

 raised reticulations. The micropylar end is provided with a short 

 stalk, capped by a pure white knob.
