PYROTA. 435 
11. Pyrota bilineata. 
Pyrota bilineata, Horn, Trans. Am. Ent. Soe. xii. p. 115, t. 5. fig. 221. 
Hab. Norra America, Colorado and Arizona !.—Muexico, Northern Sonora (Morvi- 
son). 
Received by us in numbers from Morrison as from Sonora. 
12. Pyrota hirticollis. (Tab. XX. figg. 9, ¢; 9a, labium; 96, maxillary 
palpus, ¢; 9, profile of cedeagus.) 
Head and prothorax shining, reddish-testaceous, the prothorax with two spots on the disc and two on the 
flanks, the eyes, and labrum black, the elytra dull reddish-brown, the antennew, legs (the rufous base of 
the femora excepted), and underside black ; the head sparsely, the prothorax thickly, clothed with erect 
yellowish-cinereous hairs, the elytra also with a few very widely-scattered, shorter, erect hairs; the 
metasternum thickly, the rest of the under surface very sparsely, clothed with long hairs. Head sparsely 
and somewhat coarsely punctate, sulcate on the vertex, the eyes large, feebly emarginate ; apical joint of 
the maxillary palpi (¢ ) exceedingly broad and scaphiform, concave beneath, that of the labial pair (¢) 
also very stout; antenne rather slender, setaceous, joints 3-10 subequal in length, but diminishing in 
thickness ; prothorax'narrower than the head, longer than broad, narrowing in front, depressed in the 
centre behind and broadly transversely flattened before the middle, thickly and somewhat coarsely 
punctate, with a smooth, flattened, longitudinal median space; elytra about twice as wide as the 
prothorax, elongate, vaguely, broadly, and rather deeply sulcate, sharply margined at the sides and along 
the suture, and with four fine distinct raised lines, the surface (except at the base) closely and minutely 
punctured ; beneath very shining, with widely-scattered minute punctures, the metasternum more 
closely punctate; legs rather slender, the hind tibial spurs subequal; the three basal joints of the 
anterior tarsi produced on their inner side at the apex, and the sixth ventral segment entire, in the male. 
Length 15-21 millim. (¢ Q.) 
Hab. Mexico, Acapulco (Hége). 
One female and two males of this very distinct species were obtained by Herr Hoge. 
The somewhat thickly punctured, hairy thorax, and the sulcate unicolorous elytra 
distinguish P. hirticollis at a glance from all the allied forms. The elytral pubescence 
is easily abraded, and it is probable that the elytra themselves are discoloured (by 
immersion in alcohol) in the specimens described. 
13. Pyrota mariarum, 
Rather slender, luteous, the head with the labrum, a transverse spot between the eyes, the eyes themselves, 
and sometimes the sides behind, black ; the prothorax piceous or black, with an elongate-triangular 
median patch in front, sometimes extending to the base, and the basal margin, luteous; the antenne, 
underside, and legs (except sometimes the base of the femora) black; the head and prothorax sparsely 
clothed with erect hairs, the elytra also with a few shorter hairs; the metasternum thickly, the rest of 
the under surface sparsely, clothed with long hairs. Head with a few widely-scattered punctures, sulcate 
on the vertex, the eyes large, feebly emarginate; antenne and palpi as in P. hirticollis; prothorax 
slightly longer than broad, very sparsely and finely punctate, with a smooth median space; the rest as 
in P. hirticollis. 
Length 10-13 millim. (¢ 9.) 
Hab. Mexico, Tres Marias Is. (forrer).
