placed spots of variable size on the disc, and often an additional spot on either side in front of these, 
black ; the elytra yellow, with three broad black fasciee—one immediately below the base, one slightly 
postmedian, and the third apical, the anterior two more or less excised in front and behind and not quite 
reaching the suture or lateral margin, the apical one excised in front and extending completely across ; 
legs reddish-yellow, with the tips of the femora and of the tibie to a greater or less extent, and the 
tarsi entirely, black; antenne black, the basal joint sometimes partly reddish-yellow ; beneath reddish- 
yellow, the breast, abdomen, and cox more or less marked with black; palpi black; the entire upper 
surface shining. Head very sparsely punctured, the eyes large ; apical joint of the maxillary palpi in the 
male very stout, transversely pyriform, concave and spongy-pubescent beneath, the second and third 
joints thickly clothed with long hairs on their lower face; antenne strongly setaceous, joint 3 rather 
longer than 4 in the male, subequal with it in the female, the basal joint more elongate and more dilated 
at the apex in the male than in the female; prothorax longer than broad, narrowing anteriorly, the 
surface with a few, widely scattered, fine punctures, the disc foveate in the middle behind: elytra parallel 
finely and moderately densely punctate, with a few widely scattered coarser punctures, the dise with 
three feebly raised lines. 
Var. The elytra, except at the base, more densely punctured and duller. 
Length 94-18 millim. (¢ 9.) 
Hab. Mexico, Villa Lerdo in Durango, Chihuahua City, Monterey in Nuevo Leon 
(Hoge). 
Capt. Casey, to whom I have ‘communicated a specimen (¢ ), informs me that this 
insect cannot be treated as a variety of P. terminata, Lec., nor of P. concinna, Casey. 
According to him, it is somewhat intermediate, but differs from both by the structure of 
the maxillary palpi of the male and by the elytral maculation. 
Pyrota divirgata (p. 433). (Tab. XXI. figg. 16, 17, 3, varr.) 
We figure two males of this species: one (fig. 16), a pale variety, from Matamoros 
Izucar; the other, from Chilpancingo (fig. 17), represents the var. clavipalpis, Haag.
