400 TROGOSITIDA.

I have not seen any example of this species from our region; but as it occurs in 
Lower California, it may probably be detected in Northern Mexico. Not much 
reliance can be placed on Reitter’s record of the species as Mexican. 
The characters by which this may be distinguished from 7’. preterita will be found 
mentioned under that species. 
This insect is named Z’.. virescens, Fabr., in collections and by recent writers; but it 
can scarcely be the 7. virescens of Fabricius’s description ; and I have therefore adopted 
a more recent name. 
10. Temnochila dryadis. 
Trogosita dryadis, Reitter, Verh. Ver. Briinn, xiii., Abhandl. p. 30°. 
Hab. Mexico 1. 
From the brief description, I infer that this is probably a colour-variation of 
T. chlorodia. It was described from a single female example. 
11. Temnochila preterita, sp. n. 
Subdepressa, lete viridis, nitida, antennis pedibusque nigricantibus; capite prothoraceque crebrius fortius 
punctatis; elytris minus fortiter sed evidenter punctatis, punctatura serierum interstitiarumque fere 
eequalibus ; abdomine sat crebre fortiter punctato. 
Long. 12 millim. 
Mas, area submentali parce punctato, medio fasciculo parvo armata ; abdomine segmentis 2°-4™ tantum ad latera 
punctis adjectis parum numerosis. 
Hab. Mexico, Las Vigas (/ége). 
This species is extremely similar to the North-American 7. chlorodia; but it may be 
distinguished by the less amount of difference between the punctuation of the interstices 
and those of the striz, and by the anterior angles of the thorax being more acute, also 
the prosternal process has its hind margin more depressed and flatter. It is equally 
similar to the small varieties of 7. planipennis, but it has the thorax scarcely at all 
angulate at the sides, and not abruptly narrowed in its basal part, the humeral angles 
of the elytra not rounded, and the antenne not metallic in colour, even the basal 
joint being scarcely at all viridescent in front; the punctuation of the upper surface 
is considerably coarser than in any example I have seen of 7. planipennis. I have seen 
only three examples of the species, but after comparison with a series of 7. chlorodia I 
have no doubt the two are distinct.
