220 HETEROMERA. 
punctured before the middle, deeply impressed behind, the interstices flat, exceedingly minutely and closely 
wrinkled (more evident than on the prothorax), and with numerous scattered very fine punctures, the 
margins reddish-testaceous, the testaceous colour extending (as in P. dytiscoides) a little upwards along 
the suture at the apex and a little inwards at the base. 
Length 6 millim. 
Hab. Panama, San Miguel in the Pearl Islands (Champion). 
One example. Closely allied to P. dytiscoides, but with the thorax comparatively 
broader (especially anteriorly), the sides more rounded, and the surface duller; the 
elytra (as in P. dytiscoides) margined with testaceous. 
6. Phaleria pilatei. 
Phaleria pilatei, Chevr. Comptes Rendus de la Soc. Ent. Belg. xxi. p. ccxlix’. 
Hab. Mexico, Yucatan (Pilate 1). 
Unknown to me. According to the description (Joc. cit.) this is an elongate, mode- 
rately convex species; the upper surface testaceous and shining, the eyes black, the 
thorax narrowly margined at the base, the elytra finely striate. 
7. Phaleria pacifica. 
Elongate oval, convex, black, shining. Head transversely impressed in front, finely and sparingly punctured, 
the orbits reddish ; prothorax rather broader than long, comparatively elongate, widest a little before the 
base, the sides almost straight behind the middle, rounded and narrowing anteriorly, the apex feebly 
emarginate, the anterior angles almost rounded, the base narrowly margined and with a longitudinal 
impression on each side, the surface exceedingly finely and sparingly punctured, the margins sometimes 
lighter ; elytra scarcely wider than the prothorax at the base, the humeri not prominent, regularly striate, 
the strie punctate before the middle and as usual more deeply impressed behind, the interstices very 
finely and somewhat closely punctured ; legs and antennz ferruginous, the femora and tibie more or less 
infuscate. 
Length 53-6 millim. (¢ 2.) 
Hab. GuateMaLa, Champerico, San José (Champion); Nicaraaua, Corinto (Cham- 
pion). 
Hight examples. This species may be known by its shining black colour, elongate 
and convex form, and comparatively long thorax; it is apparently allied to P. picipes, 
Say, from the southern and middle Atlantic coast. 
** Base of the thorax not margined. 
8. Phaleria neotropicalis. (Tab. X. fig. 3.) 
Hliptic, moderately convex, testaceous, dull, scarcely shining. Head piceous, the anterior half more or less 
reddish-testaceous, finely and sparingly punctured; prothorax transverse, the sides very feebly rounded 
and obliquely converging from the base, the apex arcuate emarginate, the anterior angles prominent, the 
base not margined and with a shallow oblique fovea on each side, the surface almost impunctate, the base 
sometimes very narrowly darker ; elytra scarcely wider than the prothorax at the base, the humeri rounded 
and not prominent, widest a little before the middle, very finely striate, the strix obsolete before the 
middle, lightly impressed behind, the interstices flat, the entire surface (if viewed with a lens) exceedingly 
minutely and closely wrinkled, the dise with a large common black or piceous scutiform patch extending
