ZYGOGRAMMA. 249 
Zygogramma conjuncta (p. 215). | 
To the Mexican locality given, add:—Durango city (Hége), Monclova and Parras 
in Coahuila (Dr. Palmer). 
It is somewhat doubtful whether the Mexican examples are really conspecific with 
Z. conjuncta (Rogers). The elytral markings of the latter, as figured by the author, 
are not like those of our specimens, but agree exactly in pattern with Z. tortuosa 
(Rogers) ; the design of the thorax, however, resembles that of the Mexican insect, the 
thorax in Z. tortuosa being unicolorous. 
Zygogramma, lepidula (p. 216). 
To the Mexican localities given, add :—Salazar, Huitzilac in Morelos, Cholula in 
Puebla (Hége). 
Zygogramma morbillosa (p. 216). 
To the Mexican localities given, add :—Chilpancingo in Guerrero (H. H. Smith). 
The specimens obtained by Mr. Smith vary so much amongst themselves, and also 
from the type, in regard to the elytral design, that it is impossible to come toa decided 
opinion as to whether they really belong to one species or not ; the shape and position 
of the spots cannot be described in words, as they are frequently asymmetrical. 
30. Zygogramma, fasciatipennis. (Tab. XLI. fig. 6.) 
Obscure greenish-sneous; the head and legs fulyous; thorax closely punctured, flavous, the posterior portion 
fulvous; elytra strongly punctured, flavous, a sutural stripe (divided anteriorly), two stripes on the disc, 
joined at the apex, and the posterior portion of the lateral margin, piceous. 
Length 34 lines. 
Hab. Mexico, Northern Sonora (Morrison). 
This insect resembles Z. conjuncta (Rogers), from which it differs in the strongly 
punctured elytra, and in their fulvous epipleure and dark posterior portion of the 
lateral margin; Z. exclamationis (Fabr.) and several other allied species are without a 
marginal stripe. ‘The elytra are entirely devoid of spots; the terminal joints of the 
antenne are black (as usual) ; the head is closely, the thorax more sparingly punctured 
(finely on the disc, strongly at the sides); the basal band of the thorax is much widened 
inwardly and sinuate or dentate on its anterior margin, though variable in this respect ; 
the elytral stripes are of almost equal width and nearly black—the discoidal ones 
coalesce at the apex and are produced into a point, the outermost of the two being 
slightly sinuate exteriorly—and strongly and closely punctured, the interstices more 
sparingly so and somewhat convex; the underside has a more or less metallic eneous 
gloss over a dark fulvous ground-colour; the claws are united at the base.
