A452 RHYNCHOPHORA. 
Hab. Guatemata, Totonicapam between 8500 and 10,500 feet (Champion). 
One specimen. This minute Cryptorrhynchid has a very different facies from the 
typical species of the genus Microhyus, owing to its long, subcylindrical prothorax 
and narrow elytra; but it is not very far removed from M. montanus. ‘The open 
rostral canal separates it from Acalles and other “ Tylodides.” 
JENESIAS, gen. nov. 
Rostrum stout, very strongly curved, moderately long, the scrobes deep and descending at once to the lower 
side, but not contiguous beneath; antenne with a 7-jointed, slender funiculus, the club ovate, stout, 
with distinct sutures; eyes large, finely facetted, rather prominent, about half covered by the well- 
developed ocular lobes of the prothorax; scutellum oval, small; elytra much wider than the prothorax, 
' 10-striate ; prosternum with a rather deep rostral canal; anterior cox moderately, the intermediate 
pair more widely, separated; mesosternum concave ; metasternum declivous in the middle in front, 
plicate or not at the sides, the episterna rather broad ; ventral segments 3 and 4 together a little 
longer than 2, all the sutures distinct, straight ; femora dentate; tibize sharply unguiculate at the outer 
apical angle; tarsi with joint 3 bilobed, the claws divergent, simple. 
The three small species placed under #nesias have somewhat the facies of various 
aberrant Zygopina, owing to their large, finely facetted, partially exposed eyes; 
nevertheless the well-developed ocular lobes of the prothorax show that they are 
more nearly related to Conotrachelus. In general appearance they superficially 
resemble certain Barids. The species selected as typical, #4. tuberculirostris, has a 
prominent tubercle at the apex of the rostrum beneath, this being absent in the 
two others. 
a. Rostrum tuberculate at the apex beneath; mesosternum with a small 
prominence in front of each of the intermediate coxe; metasternum 
plicate at the sides; elytral interstices sharply, narrowly costate, the 
seriate punctures fine . . . 2. 1 ee + + + ee ee + buberculirostris, sp. n.

base, the seriate punctures coarser.

1. Ainesias tuberculirostris, sp.n. (Tab. XXII. figg. 7, 7a, 0.) 
Subovate, shining, black, sometimes mottled with rufo-piceous, the antenne, and the tips of the tarsi, or 
the whole of the legs, reddish ; clothed with scattered ochreous or greyish scales, which are condensed 
into a median vitta and a spot on each side of the prothorax and a subapical fascia on the elytra, the 
vestiture of the under surface almost entirely greyish. Head closely, finely punctate, slightly depressed 
between the rather prominent eyes, the latter separated by about one-half the width of the rostrum ; 
rostrum as long as the head and prothorax, stout, abruptly curved in its outer half, slightly swollen 
towards the base, rugulosely punctate and finely unicarinate, armed with a smooth prominent tubercle 
at the apex beneath, the antenne inserted at about one-third from the tip, joint 2 of the funiculus
