absence of the diagnostic, wing-like expansions of the aedeagus so 
characteristic of A. jeanneli (Valentine, 1952). The + ’s and — ’s 
in couplets 10 and 1 1 are a shorthand for presence ( + ) or absence 
(- — ) of the anterior discal, posterior discal, and anterior apical 
punctures, respectively, of the elytra. 
A Prospectus of the North American Trechinae 
The following classification is within the framework proposed 
by Ueno (in Ueno and Yoshida, 1966, footnote, p. 77). The starred 
(*) subtribes are not represented in North America. Other than 
adding newly described genera, I have diverged from the “series” 
classification of Jeannel (1928) only in putting Lasiotrechus into 
the Trechoblemus series. The “Darlingtonea series” is a new 
category for two genera described by Valentine (1952) and seen 
by Jeannel only a year before his death. He felt that Ameroduvalius 
was not closely related to any trechine genus known to him and had 
the impression that Darlingtonea was very close to Pseudanophthal- 
mus (Jeannel, in litt.). Quite probably Jeannel relied on the 
aedeagal figures drawn by Valentine (op. cit.), and was thus misled 
about the nature of the transfer apparatus in Darlingtonea ; instead 
of consisting of two spatulate sclerites, the Darlingtonea copulatory 
pieces are dorsal/ventral and isotopic, like the two halves of a box.
