CRYPTORRHYNCHUS. 671 
punctate prothorax, and the albo-annulate legs, distinguish C. octonotatus from its 
immediate allies. It approaches C. obtentus. 
70. Cryptorrhynchus evanescens, sp. n. (Tab. XXXIII. figg. 6, 6a, 2.) 
Elongate-ovate, black, the antennx forruginous; densely clothed above and beneath with pale brownish 
scales, the prothorax and elytra with a common broad blackish space extending down the disc (which is 
abruptly narrowed in front and gradually narrowed behind, and about reaches the apical declivity of the 
elytra), the upper surface also set with scattered, coarse, blunt, light and dark, setiform scales, each of 
the granules on the elytral coste being followed by a large raised scale, the tibiz fusco-annulate at the 
base. Head rugulosely punctate, the eyes widely separated ; rostrum strongly curved, about as long as 
the prothorax, widened, rugulosely punctate, and feebly carinate at the base, and minutely punctate 
thence to the tip, the apex somewhat flattened, the antenne inserted towards the base, joints 2-7 of the 
funiculus slender, 1-3 elongate, 2 slightly longer than 1, the club stout, ovate. Prothorax transverse, 
abruptly narrowed and strongly constricted in front, the sides subparallel behind: densely, finely 
punctate, the posterior lobe carinate and broadly flattened down the middle, and somewhat hollowed 
exterior to this. Scutellum rounded. LElytra oblong-oval, very little wider than the prothorax, the 
humeri obtuse; seriate-punctate, the interstices rugulose, 1 (sutural), 3, 5, 7, and 9 granulato-costate, 
1 becoming more raised towards the apex. Beneath densely punctate ; mesosternum broad, horseshoe- 
shaped. Legs rather long; femora unidentate. 
Length 6,5-8, breadth 23-33 millim. (9.) 
Hab. Panama, Bugaba (Champion). 
Three specimens. Very like Cryptorhynchus dorsalis, Ros., and similarly coloured, 
but with the prothorax subparallel at the sides posteriorly; the elytra with the 
alternate interstices granulate and more raised, the setiform scales coarser, the seriate 
punctures finer and almost hidden by the dense vestiture ; the ventral segments 2-4 
subequal in length. Siron (Ccelosternus) dorsalis, Ros., has broader metathoracic 
episterna, a shorter second ventral segment, &c. 
71. Cryptorrhynchus dorsalis, (Tab. XXXIII. tig. 7, 2.) 
Cryptorhynchus dorsalis, Ros. in Schénh. Gen. Cure. iv. p. 101’. 
Hab. Mexico, Vera Cruz (Chevrolat 1), Toxpam (Sallé). 
The type of this species cannot now be found in the Stockholm Museum, but we 
have received a single example from Mexico that agrees with Rosenschoeld’s descrip- 
tion. It has the metathoracic episterna very narrow at the middle, as in Diaporesis. 
The mesosternum is prominent, and arcuate-emarginate in front. The femora are 
unidentate. The length of our specimen is 7+ millim. 
72. Cryptorrhynchus eruptus, sp.n. (Tab. XXXIII. figg. 8, 2; 9, var.) 
Oblong-ovate, black, the antenne and tarsi more or less ferruginous; densely clothed with whitish or pale 
brown scales, the prothorax with a broad space down the middle, which is abruptly narrowed anteriorly, 
and the elytra with a large transverse space at the base and another at the middle, these markings 
connected along the suture, and sometimes a narrow fascia and a small spot towards the apex, black, the 
femora and tibiz nigro-annulate; the upper surface also set with short, erect, black and pallid sete, 
the black setee clustered into two small fascicles on the prothorax in front, the legs setulose. Head
