The description is based on an unrecorded number of specimens from 
MASSACHUSETTS submitted by Dr Harris. 
Type-material: not found in the ANS, Philadelphia, see note on the Say 
collection, p. 279. There are no specimens of this species in the Harris collection 
in the MCZ, Harvard. The type-material must therefore be regarded as lost. 
The generic attribution is based on the following specimen standing as obtecta 
Say in the BMNH: 3, Buffalo, N.Y.; Andreas Bolter Collection. 
The description of this species may have appeared before 1839, see note in the 
bibliography, p. 295. 
EIDOLUS Candéze 
Exidolus Candéze, 1857 : 178. Type-species: Eidolus linearis Candéze, by monotypy. 
GENERIC DIAGNOSIS. Each claw with a group of setae near the base (Text-fig. 11). Tibial 
spurs absent (Text-fig. 10). Mesepisternum does not form part of margin of the mesocoxal 
cavity; mesepimeron forms part of margin of the mesocoxal cavity (Text-fig. 3). Third antennal 
segment larger than the second, similar in shape to the fourth. Segments three to eleven 
pectinate. Antennal grooves shallow, occupying the anterior three-quarters of the 
prosternopleural suture. Body clothed with narrow scales. Prothorax without constriction 
behind the anterior angles; lateral carina absent. Propleurae and metasternum without 
grooves or depressions for the accommodation of the anterior and middle tarsi. Scutellum 
simple, without carina. Tarsi simple, without ventral lobes. 
HIsTORY OF THE GENUS. The genus was established for a single species with 
pectinate antennae in which the lateral margin of the prothorax is not carinate. 
SEXUAL DIMORPHISM. Unknown. The two lectotypes are the only specimens 
known to me. 
DISTRIBUTION. Brazil. 
LIFE HISTORY AND HABITS. Nothing is known of the life history and habits 
of the two species included in the genus.
