250 PHYTOPHAGA.—SUPPLEMENT. 
31. Zygogramma, obscuro-fasciata. (Tab. XLI. fig. 7.) 
Blackish-seneous, the head, thorax, and legs fulvous ; elytra pale flavous, the suture and a broad stripe towards 
the sides obscure fulvous, the disc with numerous round blackish spots. 
Length 2 lines. 
Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith). 
Very closely allied to Z. guttulosa and resembling it in colour, but differing thus :—. 
The thorax, instead of being rather strongly punctured on the disc, is nearly impunc- 
tate or very sparingly punctured ; and the elytra have an obscure broad fulvous stripe 
towards the sides and fewer spots, these being sometimes confluent and forming elongate 
marks here and there (in Z. guttulosa the entire disc is closely spotted and the fulvous 
stripe is absent). About thirty specimens were obtained. 
32. Zygogramma durangoensis. (Tab. XLI. fig. 8.) 
Dark fulvous, the terminal joints of the antenne black ; thorax foveolate-punctate at the sides; elytra flavous, | 
a sutural and a marginal stripe, three spots placed triangularly at the base, a broad curved stripe extend- 
ing from the shoulder to below the middle, and two rows of smaller spots at the sides, as well as several 
other spots near the suture, fulvous. 
Length 3-34 lines. , 
Head subremotely punctured; antenne fulvous, the terminal five joints strongly thickened, black ; thorax 
three times as broad as long, slightly widened at the middle, the sides nearly straight, strongly produced 
- and rounded in front, the surface irregularly but not very closely punctured, the interspaces somewhat 
swollen, the sides foveolate and closely punctured ; elytra punctate-striate near the suture and lateral 
margins, the disc irregularly punctured, the sutural stripe suddenly narrowed below the base, straight 
and of equal width posteriorly, the marginal stripe extending from the middle to the apex, the stripe at 
the shoulder broad, strongly curved, and reaching to below the middle but not to the suture, the three 
larger spots triangularly placed near the scutellum, a row of punctures running parallel with the suture 
posteriorly, and two rows of smaller punctures (unequal in size and numbers) running parallel to the 
lateral margin; underside and legs dark fulvous, the breast with a more or less distinct «neous gloss. 
Hab. Muxtco, Ventanas in Durango (Hége). 
In its markings and general colour Z. durangoensis somewhat resembles Z. lemur, 
but differs from it in having the lateral portion of the thorax rather strongly produced 
in front, causing the anterior margin to be deeply concave behind the eyes; the three 
spots near the scutellum, the broad curved humeral stripe, and the even sutural stripe 
further distinguish the species. Several specimens. 
33. Zygogramma maculicollis. (Tab. XLI. fig. 9.) 
Fulvous, the terminal joints of the antenne black; the head with a fulvous spot; thorax flavous, the sides 
and a'‘V-shaped mark on the disc fulvous; elytra testaceous, marked with numerous black spots, the 
suture and a broad stripe at the sides, fulvous. 
Length 3-34 lines. 
Head nearly impunctate, dark fulvous, the middle flavous ; antenne dark fulvous, the terminal five or six joints 
black, dilated ; thorax about twice as broad as long, the sides rather rounded, but slightly produced 
anteriorly, the surface strongly punctured towards the sides and along the basal margin, the disc nearly 
impunctate, flavous, the lateral portion partly and a V-shaped mark on the disc dark fulvous; elytra very 
strongly and irregularly punctured, with a deep and regular row of punctures accompanying the lateral
