7’. chevrolati proxime affinis, sed minor, nitidior, prosternoque inter coxas argute impresso.

Fem., abdomine segmento ultimo ventrali ad apicem leviter transversim impresso. 
Hab. Mexico, Orizaba, Parada (Sallé); GuaTemaa, Pantaleon, ZLapote (Champion) ; 
Panama, Bugaba (Champion). 
Although certainly very closely allied to the smaller and less punctate varieties of 
T. chevrolati, I have little doubt that 7. guatemalena is truly distinct. The surface of 
the thorax is of amore shining brassy colour, the minute punctuation between the larger 
punctures being finer. In the male the pubescence on the submental area is shorter, and 
the median fascicle altogether smaller, and there is no supplementary sexual sculpture 
on the sides of the ventral plate; in the female the impression on the terminal segment 
is different in shape, extending less forwards and being more distinct on each side at 
the hind margin ; and in both sexes there is a quite definite impression of the prosternum 
between the front coxe. 
Mr. Champion obtained a series of eighteen specimens at Pantaleon, agreeing 
satisfactorily, except that three of them are of the larger size (11 millim. long); from 
each of the other localities only one example is present, but they appear truly to belong 
to this species, though each of them differs slightly in unimportant details. 
Reitter has described two species closely allied to 7. chevrolati, viz. T. steinheilc and 
T. levicollis, and each agreeing in certain respects with 7. guatemalena. T. steinheitli, 
from Colombia, is said, however, to have a large angular impression (like that of 
T’. chalcea, I suppose) on the last ventral plate of the female. 7. /evicollis was described 
from a single male to which the locality Cayenne? was assigned, and is said not to have 
the anterior angles of the thorax acute, and to have no minute punctures on the thorax. 
It is impossible, therefore, to reconcile our 7. guatemalena with either of these species. 
5. Temnochila quadricollis. (Tab. XIII. figg. 5; 5a, underside of head; 
5 6, posterior part of middle of prosternum.) .
