MEGASCELIS. 51 
(Champion); Nicaragua, Chontales (Belt) ; Panama, Volcan de Chiriqui, Caldera 
(Champion).—Cotompta 1, 
Numerous specimens from the above localities agree so well with the description of 
this species that I must refer them to it. The elytra in all of them have their extreme 
apex subtruncate, and their inner angle produced into a small and more or less distinct 
tooth (Lacordaire says nothing of this tooth, which would place the insect in his first 
division), and the suture accompanied by a pale fuscous band which gradually widens 
posteriorly ; this band is similar in shape in all the specimens before me, and it seems 
to distinguish Jf. lacertina from M. suturalis, Lac., in which the band is widened 
anteriorly. | | 
Megascelis affinis (p. 18). 
To the Guatemalan locality given, add :—Senahu in Vera Paz (Champion). 
Several more specimens of this species are now before me. In these the underside 
varies in colour from metallic blue to testaceous ; the upperside is very depressed and of 
a uniform metallic dark green or eneous; and the size varies from two to four lines. 
Our insect agrees so well with Lacordaire’s description of MW. affinis that I have not 
hesitated to identify it with that species, though in the present genus only a comparison 
with the type can remove all doubt. 7 
4. Megascelis vittatipennis. 
Megascelis vittata, huj. op. p. 18 (nec Fabr.). 
Fulvous or piceous; above metallic green, clothed with yellow pubescence; head and thorax finely rugose ; 
thorax with a raised central line; elytra opaque, metallic green, with a broad subsutural fuscous or 
purplish stripe. 
Length 2-2; lines. 
Head metallic green, finely rugose, clothed with golden pubescence at the base, the epistome more coarsely 
punctured ; antenne nearly as long as the body, fuscous, the four or five basal joints testaceous ; thorax 
scarcely longer than broad, slightly constricted at the base, transversely grooved at the middle, finely 
rugose, and clothed with golden pubescence, the disc with a raised longitudinal line in the middle, this line 
being furnished at some distance from the base with a small tubercle ; elytra with the usual transversely- 
shaped punctures, the suture clothed with golden pubescence, and accompanied by a broad longitudinal 
fuscous or purplish band, followed by an equally broad metallic band occupying the rest of the sides ; legs 
testaceous. 
Hab. GuatemMata, San Isidro, Zapote (Champion). 
M. vittatipennis differs from J. vittata (Fabr.), in having the thorax much longer than 
broad and of more cylindrical shape, and the elytra, as well as their bands, more metallic. 
The present insect is of a rather opaque colour, caused by the golden pubescence; in all 
specimens the small tubercle placed on the dorsal carina of the thorax is present. This 
species was erroneously identified as J. vittata in the earlier part of this work.
