172 RHYNCHOPHORA. 
1. Sciadrusus propheticus, sp. n. (Tab. VII. fig. 9, 2.) 
Sat elongatus, niger, pallide griseo (fere albido) squamosus; elytris pone medium nigro-fasciatis vel maculatis ; 
setis erectis tenuibus superne ubique vestitus. 
Long. 44-54 millim. 
Hab. Mexico, Chilpancingo and Tepetlapa in Guerrero (H. H. Smith), Iguala 
(Hoge). 
Antenne not elongate; first joint of funiculus rather long, greatly longer than the 
second, which differs but little from the third. Rostrum rather long and slender; 
eyes oval, finely granulated. ‘Thorax hardly as long as broad, rounded at the sides 
and a good deal narrowed in front. Scutellum small, but distinct. Elytra suboblong, 
much broader at the base than the thorax, the striz quite fine. Legs hispid. 
This species is deep black, but is covered everywhere with a peculiar fine setosity— 
intermediate between sete and scales—which obscures the sculpture; this clothing is 
very readily removed, and black spaces are then left ; but in addition to these abraded 
spots, there appears to be a small fascia behind the middle which is naturally black. 
SCIOMIAS, gen. nov. 
Mentum minutissimum, a maxillis cinctum; corpus plus minusve abbreviatum, elytris convexis. 
Scape of antenne slender, rather long, bare. Rostrum short, broader at tip; scrobes 
visible from above, descending obliquely and directly from the insertion of the antenne, 
without any previous lateral prolongation. Mentum very small, forming as it were a 
shining tubercle embraced by the maxille. Prosternum in front of coxe excessively 
reduced. Hind coxe only moderately distant. Body not squamose beneath. First 
and second ventral plates rather elongate, the suture between them straight, or but 
little angulate; third and fourth plates short. Ninth and tenth striz of elytra distinct 
throughout. 
This genus may be distinguished by the form of the scrobes, which, owing perhaps 
to the abbreviation of the rostrum, pass directly downwards, and leave well-marked 
pterygia exposed. The facies is somewhat that of the European genus Platytarsus, 
but is still more like Dinas, Woll., from the Cape Verde Islands. 
1. Sciomias elegans, sp. n. (Tab. VII. fig. 10.) 
Fusco-brunneus, parce griseo-squamosus, setis erectis, crassis, pallidis armatus; antennis, tibiis tarsisque 
testaceis ; elytris valde convexis, fortiter punctatis. 
Long. 44 millim. 
Hab. Mexico (Truqui), Amula in Guerrero (H. H. Smith). 
Antenne unicolorous, yellow, scape bisinuate, first joint of the funiculus twice as 
long as the second. Rostrum quite short, broader at the tip; eyes round, convex,
