24 RHYNCHOPHORA. 
Var. Niger, vix violaceo-tinctus, elytris parcius punctatis. 
Hab. Guatemaua, Senahu (Champion). 
This species is similar to R. rufiventris, but the ventral segments are quite black, and 
the thorax is a little more slender. The punctuation is much the same in the two 
species, and there is but little difference in their sexual distinctions. I include a 
pair nearly black in colour as a variety, though it may probably prove distinct. 
Like R. rufiventris, this insect does not appear to be common, but I have seen eleven 
specimens from the various localities. 
22. Rhynchites centralis, sp.n. (Tab. I. fig. 19.) 
Violaceo-niger, nitidus, elytris violaceis ; crebre punctatus, nigro-setosus, scutello elytrorumque sutura in parte 
basali, pectorisque lateribus albido-pubescentibus. 
Long. cum rostro 7 millim. 
Hab. Guatemaua, Capetillo (Champion), Aceytuno 5100 feet (Salvin). 
We have only two examples (of the male sex) of this species; though very similar 
to R. championi it may be easily enough distinguished by the less scanty punctuation. 
‘he vertex is densely punctured, and the thorax is finely and rather closely punctured ; 
the elytra have avery distinct evenly distributed punctuation, which, though not dense, 
is more numerous and distinct than it is in Lt. championt, and the white pubescence at 
the apex is conspicuous, as also is the white hair on the under surface. 
23. Rhynchites mixtus, sp. n. 
Nigro-violaceus, nitidus, crebre punctatus, griseo-setosus, corpore subtus griseo-pubescente, pectore ad latera 
minus argute albido-cincto ; scutello elytrorumque sutura albido-pubescentibus. 
Long. cum rostro 8 millim. 
Hab. Mexico, Juquila (Sallé, Hoge). 
We have only two females of this species; it appears to be nearest to R. centralis, 
but has the white hair on the upper surface much more largely developed. The sete 
consist to a great extent of upright white hairs, and the white pubescence on the 
suture, instead of being condensed on the basal part, is evenly distributed along the 
whole length ; the white pubescence of the under surface is similarly diffuse. 
24. Rhynchites inermis, sp. n. 
Nigro-violaceus, nitidus, minus dense hirsutus, parcius obsoletiusque punctulatus, scutello elytrorumque sutura 
in parte basali, elytris apicem versus, pectorisque lateribus albido-pubescentibus. 
Long. cum rostro 6-7 millim. 
Hab. Costa Rica, Cache (fogers); Panama, Volcan de Chiriqui 3000 to 4000 feet 
(Champion).
