Maris quam femine statura magis angusta, antennarum flabello 
magis elongato. lLong., 3 1.; lat., 12—1,4 1. 
_At once distinguishable (in the group of Liparetri having the 
antenn 9-jointed, the clypeus more or less rounded or subtrun- 
cate in front, and the body glabrous, or nearly so, above) by its 
uniform pale testaceous color. The flabellum of the antenne is 
nearly white.

C. palpalis, sp. nov. Sat elongata; nitida; supra subglabra, 
prothorace et elytrorum basi capillis elongatis fimbriatis ; 
subtus (abdomine pygidioque capillis subtilibus erectis spar- 
sim vestitis exceptis) dense hirsuta ; albido-testacea, capite 
(hoc plus minusve infuscato) pedibusque (horum dentibus 
spinis et carinis plus minusve infuscatis) rufescentibus, pro- 
thorace pallide brunnescenti; capite fortiter sat crebre 
rugulose (clypeo, parte postica excepta, subtiliter nec rugu- 
lose), prothorace subtiliter sparsissime, elytris (his obsolete 
geminato-striatis) leviter vel vix manifeste, pygidio leviter 
sparsissime, punctulatis ; antennis 9-articulatis ; prothorace 
quam longiori fere duplo latiori, antice modice angustato, 
obsolete canaliculato, basi vix bisinuata, lateribus fortiter 
rotundatis, angulis anticis acutis posticis rotundatis ; ely- 
trorum apice haud producto. 
Maris antennarum flabello quam articuli precedentes 5 conjuncti 
sat longiori; palporum maxillarium articulo apicali dilatato, 
quam precedentes 2 conjuncti sat longiori; tibiis anticis 
(exempli typici) carentibus. 
Femine antennarum flabello quam articuli preecedentes 5 con- 
juncti vix longiori; palpis maxillariis normalibus; tibiis 
anticis extus fortiter 3-dentatis. Long., 10 1.; lat., 541. 
This insect is very remarkable by reason of the form of the 
palpi in the male, which are fully as long as the head, the apical 
joint being dilated and especially elongate; its form is curved 
and its upper surface is deeply bisulcate, the space between the 
sulci convex, presenting the appearance of the joint being a husk 
split open lengthways and revealing an enclosed kernel. It is 
unfortunate that the only male in the collection has lost its front 
legs as without examining those organs it seems just possible that 
the species ought to be regarded as an aberrant member of the 
Clavipalpides. Its simple claws, however, and mandibles of the 
Sericoid type point strongly to the probability that the front 
legs of the male are not of the Clavipalpid type. I have dis- 
ected a female and failed to find any character to distinguish it 
rom a female Colpochila, so I feel little doubt that the insect
