LIXOMORPHA.—ANCHONOMORPHA. 63 
funiculus 7-jointed, joint 2 slightly shorter than 1 inthe g and much longer than it in the 9? ; scutellum 
very small, transverse as seen from above; anterior cox contiguous, the intermediate pair very narrowly 
separated ; metasternum about as long as the first ventral segment, the episterna very narrow in the 
Q, broader in the ¢ ; legs long and rather slender, the femora moderately clavate and armed with 
a short tooth towards the apex, the tibiz sinuous and furnished at the inner apical angle with a sharp 
claw, which is preceded by two matted spine-like tufts of hair, the tarsi elongate. 
This genus, which includes a single species from Costa Rica *, is closely related to 
Hilipus (Sect. I.), but differs from it in the small transverse scutellum, the feebly dentate 
femora, the laterally placed eyes (which are separated by a space fully equalling 
the width of the rostrum), &c. In general facies, Livomorpha resembles Callinotus 
and Desmosomus, of the group Cholina, but in these latter the anterior and intermediate 
coxee are more or less widely separated. The sexual differences in the form of the 
rostrum and antenne are very remarkable. The genera Cheris, Pasc., and Hpistrophus 
and Ischiomastus, Kirsch, also have the eyes similarly placed, but they are not other- 
wise very nearly related to Lixomorpha. 
1. Lixomorpha albomarginata, sp.n. (Tab. IV. figg. 26, 26a, 3; 27, 2.) 
Elongate, subfusiform, opaque, the rostrum and under surface shining ; the head, prothorax, and elytra each 
with a marginal stripe of white or pale ochreous scales, those on the head narrow and the others rounded, 
the rest of the surface with widely scattered similarly coloured scales. Head shallowly foveate between 
the eyes, almost smooth ; rostrum moderately curved, in the ¢ a little shorter than the prothorax, 
closely punctured at the sides, smooth at the tip, carinate along the middle, and about one-half the width 
of the apex of the prothorax, in the Q@ longer and smoother, cylindrical, and comparatively slender ; 
joint 2 of the funiculus a little shorter than 1 in the g, and at least twice as long as it is in the Q. 
Prothorax as long as broad, subconical, narrowing from a little before the base to the apex, the base 
deeply bisinuate, the surface with extremely minute, scattered, shallow punctures, and with indications 
of a smooth raised median line. Elytra elongate, much wider than the prothorax, narrowing almost from 
the base, conjointly rounded at the apex, flattened on the inner part of the dise and obliquely sloping 
towards the outer margin, the base trisinuate and with the margin raised and thickened on either side of 
the scutellum ; seriate-punctate, the interstices flat and almost smooth, the third appearing a little raised, 
but not callose towards the tip. Venter sparsely punctate, and in the ¢ with a broad, deep, oval 
depression extending down the middle of the first and second segments. 
Length 11-13, breadth 4-42 millim. (¢ @.) 
Hab. Costa Rica, Rio Sucio, lrazu (Logers). 
Two females from Irazu and a male from Rio Sucio, all in a rather bad state of 
preservation. 
ANCHONOMORPHA, gen. nov. 
Antenne inserted near the apex of the rostrum, funiculus 7-jointed, joint 1 stouter than those following ; 
rostrum stout, similar in form in the two sexes, the scrobes deep, visible from above in front, descending to 
the lower anterior margin of the eye; eyes coarsely facetted, lateral, separated by a space fully as wide as 
the rostrum, transverse, narrow and oblique as seen from above; prothorax very deeply and abruptly 
arcuato-emarginate at the apex beneath, the prosternum broadly depressed along the middle; scutellum 
small, oval ; elytra with series of rounded or oblong squamigerous prominences ; anterior coxze contiguous ; 
* There is an undescribed species from Colombia in the British Museum, labelled Heilipus callinotoides, 
Jekel, that may belong to it.
