RECLASSIFICATION OF SUBFAMILY AGRYPNINAE 57 
(BMNH). The absence of a Candéze determination label may be due to the fact 
that Candéze accepted Janson’s name and did not trouble to affix a label himself. 
The specimen lacks two features which are characteristic of the genus Opatelus. 
The third antennal segment does not resemble the second and there are no tarsal 
grooves on the metasternum. It must be assumed that the very small size of 
the specimen (4 mm) led Candéze to make this mistake in the generic attribution.

This is a distinctive and easily recognizable species and I have therefore accepted 
Fleutiaux’s synonymy. Both species are from the same locality and may well be 
part of the same series.

The description is based on an unrecorded number of specimens from New 
Hampshire submitted by Dr Harris. There are no specimens in the Say collection 
in the ANS, Philadelphia (see p. 279). The specimen measures 13 mm compared 
with the published length of ‘eleven-twentieths of an inch’ [= 14.3 mm]. 
The date of publication of the description is 1839 (not 1836) but it may have 
appeared earlier, see note in the list of references p. 295. 
I am greatly indebted to Professor Darlington for locating this specimen and 
supplying me with the data from Harris’s notebook.
