SUNIUS. 599 
Hab. Mexico, Teapa (Pilate). 
This insect is closely allied to S. subtilis, but is considerably smaller; the elytra 
are yellow behind, and the yellow colour extends forwards along the suture for 
about two-thirds of the length. The hind body is very slender and almost linear, 
quite finely punctate. The male has a deep narrow excision on the last ventral 
plate. 
This is also known to me only by one exponent, obtained from Chevrolat’s collection, 
where it was labelled S. limbatus, Er., an evidently erroneous determination. 
8. Sunius centralis. 
Sat angustus et elongatus, dense fortiter punctatus, subopacus, niger; antennis, palpis, pedibus elytrorumque 
margine posteriore pallide flavis. 
Long. 43 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne very long and slender, rather longer than the head and thorax. Head sub- 
oblong, broad, dilated in front, and with distinct pterygia; eyes convex, placed almost 
behind the middle of the sides; the surface sculptured with fine thread-like reticula- 
tions. Thorax rather small, considerably narrower than the head or the elytra, much 
longer than broad. Elytra rather broad, slightly longer than the thorax, densely and 
deeply punctate, a little shining, the posterior portion definitely pale. 
A single female only has been procured. 
9. Sunius pilatei. (Tab. XV. fig. 18.) 
Nigricans, antennis, palpis pedibusque pallide flavis, elytris testaceis, ad latera nigris; abdomine fortiter 
punctato. 
Long. 4 millim. 
Hab. Mexico, Teapa (Pilate); Guatemaua, Zapote, San Isidro (Champion). 
Head broad, evidently broader at the distinct pterygia; eyes convex ; vertex narrow. 
Thorax rather slender, much longer than broad, greatly narrowed behind, like the head 
covered with a reticulate sculpture. Elytra scarcely longer than the thorax, coarsely 
punctate. Hind body rather broad, broader behind, bearing coarse deep punctures 
arranged rather irregularly in a transversely linear manner ; with a scanty but rather 
long griseous pubescence. The male has the penultimate ventral segment flattened and 
polished along the middle, and a rather broad and short excision at the extremity of 
the last segment. 
Mr. Champion obtained a small series of this species. The Mexican exponents are 
from Chevrolat’s collection, where one was labelled S. pélatei, Chevr., and a second 
(immature) S. lateralis, Er. Fauvel had corrected the error as to the latter example 
by uniting it with the other under the name S. linewentris, Fauv., ined. Having thus 
two names to choose from, I have elected to preserve the older.
