and in fact can only be detected with difficulty. Moreover, in the female of 7. foveicollis 
the last ventral segment is almost unimpressed, while in 7. geminata the impression on 
this segment is larger and more distinct than usual, the species being in this respect 
intermediate between 7’. chalcea and T. chevrolati. 
We have received only four examples of 7. geminata. 
Group D.—Prosternum behind the coxe not margined, excessively coarsely punctate. 
Mandibles and labiwm elongate. (Species 8.) 
8. Temnochila salvini, sp. n. (Tab. XIII. fig. 6.) 
Elongata, sat convexa, nigro-enea, supra «nea, pedibus nigris, antennis piceo-nigris; capite prothoraceque 
elongatis, dense fortiter punctatis, hoc post medium profunde impresso ; elytris densius punctatis. 
Long. 10-15 millim. 
Mas, area submentali medio tuberculo sat magno sed perparum elevato; segmentis ventralibus 2°-4™ sat crebre 
fortiter punctatis, inter puncta majora punctis minutis parum numerose adjectis. 
Fem., area submentali laevigata; abdomine segmentis ventralibus 2°-4™ crebre fortissime punctatis. 
Hab. Panama, Bugaba, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
We have no other species that can be confounded with this, on account of the very 
dense punctuation of the elytra. The large depression on the thorax is broad, and 
does not extend forwards beyond the middle, and has no trace of longitudinal elevation 
in it; there is a much smaller depression on each side between the middle and the side, 
but no smooth space near the front angles. 
T. salvini is allied to T. punctatissima, Reitter, and 7. rugulosa, Kirsch, but differs in 
several points from the descriptions of those species, so that I have no doubt of its being 
distinct from them ; indeed in 7. rugulosa the punctures on the elytra are a great deal 
denser than in 7. salvini, although in this latter species they are much closer than in any 
other found in our region. The species of this group are almost entitled to generic 
distinction owing to the ligula being elongate, so that the labial palpi are placed far in 
front of the mentum. 
We have received a small series of 7. salvini, exhibiting very little variation, except 
in size. 
Group E.—Prosternum behind the coxe smooth, not conically prominent, without 
margin. Mandibles short. (Species 9-25.) 
In some species of this group the apex of the prosternum is protuberant, but does 
not project backwards in a conical manner. 
* Humeral angles of elytra more or less acute. (Species 9-14.) 
9. Temnochila chlorodia. 
Trogosita chlorodia, Mann. Bull. Mose. 1843, pt. 2, p. 301'; Reitter, Verh. Ver. Brinn, xiii., 
Abhandl. p. 32”.
