780 SUPPLEMENT. 
Antenne elongate, none of the joints transverse. Head black, dull, very finely 
punctate, much narrowed behind. Thorax strongly transverse, much narrower than the 
elytra, a little narrowed behind, with a very obsolete impression at the base in the 
middle; the surface dull, very minutely punctate. Elytra ample, much longer than the 
thorax, densely and finely punctate. Hind body with the basal three segments yellow, 
the next two black, the apex again yellow; the basal segments finely and not closely, 
the apical segments still more sparingly, punctate. In the male the hind margin of the 
terminal dorsal plate ends in six equidistant teeth, the outer one of which on each side 
is considerably longer than the others. 
This insect is very like a Homalota in appearance, and the size is considerably larger 
than that of any other species of Diestota. Only one example has been obtained. 
4 (a). Diestota homalotoides. 
Parum elongata, rufula, abdomine ante apicem nigricante, antennis ante apicem piceis; evidenter pubescens, 
subtiliter punctata. 
Long. 2 millim. 
Hab. Panama, Pefia Blanca 3000 to 5000 feet (Champion). 
Antenne moderately long and stout, a little thicker externally, the penultimate joints 
slightly transverse. Head rather large, nearly as broad as the thorax, obsoletely 
punctate. Thorax much narrower than the elytra, transverse but not strongly so. 
Elytra longer than the thorax, closely and finely punctate, rather densely and distinctly 
pubescent. Hind body sparingly punctate, distinctly pubescent. 
This obscure little insect is not very similar to any other of our species; I do not 
observe any sexual mark on the three examples obtained of it. 
GYROPHENA (p. 254). 
5 (a). Gyrophena equalis. 
Subdepressa, nitida, fere laevigata, testacea ; antennis fuscis, sat brevibus, articulis 5°-10™ leviter transversis. 
Long. 2 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne rather short and stout, fuscescent ; joints 3 and 4 small, 5-10 differing little 
from one another and each slightly transverse. Head small. Thorax strongly trans- 
verse, being twice as broad as long, almost impunctate. Elytra short, but longer than 
the thorax, almost impunctate, and with very scanty pubescence. Hind body impunctate. 
The male has two small tubercular elevations on the penultimate dorsal plate; and the 
hind margin of the terminal plate is armed with two rather stout, not very distant, 
strongly curved teeth. Two examples. 
This little insect has quite the appearance of the ordinary European species of the 
genus, but is not very closely allied to any other of our region.
