all the Tropical American species described under Tele- 

 phorus * are referable to Chauliognathus, Discodon, or 

 Polemius. 



PODABRUS. 



Podabrus, Westwood; Gorham, Biol. Centr.-Am.,Coleopt. 

 iii, 2, p. 284 (1885). 

 Gorham described a single species of this holarctic genus 

 from N. Mexico, his types of which are males. A second, 

 from Durango, was subsequently received from Hoge. 

 Two Miocene forms from Florissant have recently been 

 named by Wickham. In Podabrus eight ventral segments 

 are exposed, the eighth being oval and uncleft in ^. The 

 evaginated membranous internal sac of the aedeagus is 

 shown on Plate IV, fig. 2. 



1. Podabrus mexicanus. 



Podabrus mexicanus, Gorh., loc. cit. ; Schaeff., Journ. 

 N. York Ent. Soc. xvi, p. 62. 



^. Eighth ventral segment rather large, oval ; ninth segment 

 broadly semicircularly excavate, divided towards the apex into 

 two rather broad, sinuous, concave subacuminate lobes,, the 

 corresponding dorsal segment also bilobate, the two lobes broadly 

 rounded at the apex. (Fig. 1.) 



Hob. North America, Huachuca Mts., Arizona ; 

 Mexico, Chihuahua. 



2. Podabrus caliginosus, n. sp. 



Elongate, narrow {^), broader ($), black, the base of the mandi- 

 bles, the sides of the head in front, and the prothoracic margins 

 obscure testaceous or rufo-testaceous. Head together with the 

 prominent eyes broader than the prothorax in ^, narrower than 

 the much broader prothorax in $, coarsely, closely punctate; 

 antennae nearly reaching the middle of the elytra in ^, shorter 

 in ?. Prothorax subquadrate and very little wider than one of 

 the elytra in (^, much larger and strongly transverse in $, irregularly 

 punctate, the disc with an oblique groove on each side of the median 

 sulcus at the base. Elytra parallel, long, much broader in $, 



* T. monticola, Gorh., from Ecuador, if the intermediate and 

 posterior tarsi really have one of the claws cleft in S, must be a 

 Discodon. The cleft seventh ventral segment of (^ shows that it 

 is not a Telephorus.
