ZYGOGEAMMA. 219 



Head closely and finely punctured ; labrum fulvous ; antennae extending considerably beyond the base of the 

 thorax, fulvous, the basal joints lighter, the last five joints gradually increasing in thickness, terminal 

 joint longer than broad ; sides of the thorax rather prominently widened anteriorly and much rounded 

 there, the anterior angles moderately acute and produced, surface rather closely covered with fine punc- 

 tures, those at the sides more strongly impressed ; scutellum impunctate. Elytra substriate punctate near 

 the suture, the rest irregularly punctured, yellowish white, with a sutural cupreous band narrowed 

 behind and more or less distinctly dentate at each side below the middle ; a longitudinal band of the 

 same colour commences at the base near the shoulder, directed towards the suture as far as the middle 

 from there in a more straight line towards the apex without reaching the latter, and much narrowed at 

 its extremity ; this band has the outer margin produced in a short tooth below the base, while the inner 

 one is dentate near the middle and apex ; elytral epipleurae, as well as the underside, metallic cupreous. 

 Legs dark fulvous or piceous, with a cupreous tint ; tarsi lighter fulvous. 



Hab. Mexico, Cerro de Plumas (Hoge). 



This handsome species, of which sixteen specimens were obtained, seems allied in its 

 coloration to Z. championi, which latter may almost be regarded as a variety of the 

 present insect in which the dark cupreous colour so far predominates as to leave only 

 the lateral margin yellow. I possess, however, of both species sufficient material to 

 enable me to decide their specific value. In the present one the elytral band varies 

 also greatly in width, and is often attached to the sutural one at those places where in 

 normally coloured specimens it is dentate only. In the variety (which is also figured) 

 the dark colour has so far extended as to leave only the indications of the lighter 

 portions of the elytra in the shape of spots. In Z. championi the elytral margin is 

 always regularly shaped and never indented by the cupreous portion below the base, 

 as is constantly the case in Z. omata. 



25. Zygogramma hypocrita. (Tab. XII. fig. 20.) 



Below, head, and thorax dark metallic green, antennae and legs fulvous ; elytra testaceous, the suture, two 

 subsutural narrow longitudinal stripes, the outer one abbreviated, an angular short band at the shoulder, 

 a spot at the middle of the lateral margin, and about eleven small spots at the outer half of the elytra 

 greenish or purplish. 



Length 3^-4 lines. 



Head finely punctured ; antennas with the last five joints much thickened, the two terminal ones longer than 

 broad. Thorax of nearly equal width, the sides straight near the base, slightly rounded near the apex, the 

 anterior angles acute, but scarcely produced; disk finely and rather sparingly punctured, sides more closely 

 and strongly punctate, with an obsolete shallow fovea at each side ; scutellum impunctate. Elytra convex, 

 testaceous, a narrow sutural band slightly widened towards the base, and accompanied by a narrow stripe 

 commencing directly below the base, and extending nearly to the apex, as well as another one of half the 

 size of the second, and situated closely to it, but of rather curved shape, metallic green ; near the 

 shoulder a narrow angular stripe, and pointing inwards, extends to nearly the middle of the elytra ; close 

 to this stripe and parallel with the lateral margin six spots are placed, the former having another elongate 

 spot in the middle at its extreme edge ; at the posterior portion of the elytra four spots are situated and 

 run parallel with those at the lateral margin from the middle to the apex ; another spot is seen within 

 the extremity of the outer curved stripe ; epipleurse metallic green. 



Hab. Guatemala, Sabo {Champion). 



This species of which but two specimens were obtained, bears a curious resemblance
