672 RHYNCHOPHORA. 
densely punctate, the eyes large, distant; rostrum stout, arcuate, about as long as the prothorax, thickly 
punctate in the g, smoother in the 9, the antenne inserted behind the middle, joints 1 and 2 of the 
funiculus subequal in length, the club ovate. Prothorax broader than long, constricted and much 
narrowed in front; densely, finely punctate, and at most obsoletely carinate, somewhat flattened down 
the middle. Scutellum rounded. Elytra a little wider than the prothorax, subparallel in their basal 
half, the humeri obtuse; seriate-punctate, the interstices rugulose and subgranulate, 3, 5, and 7 raised. 
Beneath densely punctate. Mesosternum prominent, arcuate-emarginate. Femora each with an acute 
tooth. 
Var.? The black patch on the prothorax extending to the margins at the base; the vestiture of the elytra 
wholly black, with the exception of an irregular, interrupted, median fascia, a short streak on the 
shoulder, and a few small scattered spots; the apical half of the femora and the basal half of the tibie 
black ; the alternate elytral interstices less raised. 
Length 44-53, breadth 2-23 millim. (d Q.) . 
Hab. Muxico, Toxpam in Vera Cruz (Saillé), Jalapa (Hoge); GuaTemaLa, Cerro 
Zunil (Champion). 
Four specimens, the one from Jalapa belonging to the varietal form. Very near 
C. dorsalis, but less elongate ; the prothorax less dilated at the sides, and with the 
median carina scarcely visible ; the elytra with two large transverse black patches on 
the disc, connected at the suture. The N.-American Cryptorhynchus fallax, Lec., 
seems to be a nearly allied form. 
73. Cryptorrhynchus macer, sp.n. (Tab. XX XIII. fig. 10, 2.) 
Oblong-ovate, shining, nigro-piceous, the antenn and the tips of the tarsi ferruginous ; thickly clothed with 
cinereous scales, the prothorax with a broad, anteriorly constricted space on the disc, and the elytra with 
a broad, common, transverse, subquadrate patch at the base, a transverse mark beyond the middle, and 
sometimes an oblong spot on the suture towards the apex, black, the legs nigro-annulate ; the upper 
surface also set with very short, scattered, semierect, setiform scales. Head densely punctate, the eyes 
somewhat distant ; rostrum stout, curved, about as long as the prothorax, rugulose and slightly widened 
at the base, and thickly punctate thence to the tip, the apical half smoother in the 9, the antenne 
inserted towards the middle, joint 2 of the funiculus shorter than 1, the club ovate, acuminate. 
Prothorax transverse, rounded at the sides anteriorly, abruptly narrowed and strongly constricted in 
front; densely, rugulosely punctate, and with a more or less distinct median carina. Elytra very little 
wider than the prothorax, narrowing from about the middle; seriate-punctate, the interstices 3 and 5 
raised, the others feebly convex. Beneath densely punctate. Mesosternum prominent, subarcuately 
emarginate. Femora unarmed. Tibie subangulate at the base externally. 
Length 33-44, breadth 14-2 millim. (do 9.) 
Hab. Guatemata, Cerro Zunil and Capetillo, Pacific slope (Champion). 
Seven specimens. This insect is a close ally of C. dorsalis, with unarmed femora 
and differently marked elytra. The black markings are sometimes connected by a 
narrow streak along the suture, the basal one being very large and transversely 
subquadrate, the second small and transverse. 
74. Cryptorrhynchus sinuatipes, sp.n. (Tab. XXXIII. figg. 11, lla, 3; 
11 6, hind leg, ¢.) 
Oblong-ovate, black, the antenne and the tips of the tarsi obscure ferruginous; thickly clothed with rather 
coarse, pale brown, overlapping scales, the prothorax with a broad, anteriorly narrowed space extending
