CYPHUS. 239 
intermixed. Scutellum very small, depressed. Elytra moderately long, subparallel in their basal half 
in ¢, widened to the middle and broader in 9, sinuate at the base, the humeri rather prominent, the 
apices acuminate and dehiscent ; with rows of rather fine punctures, the tenth row sometimes subobsolete 
in its median third. Fifth ventral segment with an oblique impressed line on each side in front in 9. 
Legs stout, the tarsi very broad in ¢, a little narrower in 9, the anterior tibise obsoletely unguiculate. 
Length 114-15, breadth 43-6 millim. (3 2.) 
Hab. Mexico (Sallé), Acapulco, Almolonga (fége), Rincon and Dos Caminos in 
Guerrero (H. H. Smith). 
Twelve examples. ‘This species may be at once known by the dense, uniform, 
cinereous vestiture, and the four small sharply-defined black spots—two at the base of 
the prothorax and one on each shoulder of the elytra. ‘The prothorax is more even 
than in C. modestus, the central groove being shallow. ‘The short claw at the tip of 
the anterior tibie is hidden by the hairy vestiture. ‘The deciduous falciform piece 
of the mandibles is rounded at the apex. 
6. Cyphus roseiventris, sp. n. (Tab. X. fig. 19, ¢.) 
Hadrotomus roseiventris, Dupont, in litt.’. 
Oblong, black, the prothorax and elytra densely clothed with green, and the rest of the body (the lower surface 
included) with pale cupreous scales, with scattered, inconspicuous, minute, pallid hairs intermixed. Head 
and rostrum deeply sulcate; antenne rather short, stout, more slender in 9, the scape not reaching 
beyond the middle of the eyes, joint 2 of the funiculus twice as long as 1, 4-7 transverse. Prothorax 
transverse, gradually, arcuately narrowed from near the base, somewhat conical in 9, narrowly sulcate 
and more or less depressed down the middle, the base bisinuate ; closely, minutely punctate, with coarser 
punctures intermixed. Scutellum not visible. Llytra broad, moderately long, subparallel in their basal 
half in ¢ , widened to the middle in 2, sinuate at the base, the humeri obliquely truncated in front and 
somewhat prominent, the apices acuminate and dehiscent; with rows of rather coarse punctures, the tenth 
row obsolete for some distance before the middle, the interstices densely punctulate. Fifth ventral 
segment with an oblique impressed line on each side in frontin 9. Legs stout, the tarsi very broad 
in g, narrower in 9°, the anterior tibiz strongly unguiculate in both sexes. 
Length 84-10, breadth 33-43 millim. (d 9.) 
Hab. Mexico (Mus. Brit.1), Cerro de Plumas [ Palmas] (Hége). 
Two males, in good condition, in the British Museum, received in 1865 (one labelled 
with the above-quoted MS. name), and a worn pair sent us by Hége. A very distinct 
form, with the scales on the prothorax and elytra very differently coloured from the 
others on the rest of the surface. The wings are fully developed, though there is no 
visible scutellum. ‘The specitic name has been used by Boheman in Naupactus. 
7. Cyphus yucatanus, sp.n. (Tab. X. fig. 20, 2.) 
Oblong, shining, black or piceous, thickly clothed with small, cinereous or cupreo-cinereous, glossy scales ; the 
prothorax with two small spots at the base, and the elytra with two undulate or interrupted fascize on 
the disc (the anterior one extending forward to the humeral callus), dark brown. Head and rostrum 
deeply sulcate ; antennz moderately stout, rather short, the scape reaching to the middle of the eyes, 
joint 2 of the funiculus nearly twice as long as 1, 3-7 transverse. Prothorax transverse, obliquely 
narrowed anteriorly, subconical in 2, the sides subparallel behind in ¢, deeply, interruptedly, sulcate
