2. The femora not grooved or hairy on their lower edge towards the base; the tibie in their apical third 
sparsely clothed with fulvous hair within, the anterior pair more slender and less curved. 
Length 19-23 millim. (¢ 92.) 
Hab. Mxxtco, Yolotepec (Flohr), Tapachula in Chiapas (H6ége); Brivish Honpuras, 
Belize (coll. F. Bates); Guatemata, El Tumbador, Cerro Zunil, Pantaleon (Champion), 
Escuintla (Conradt); Costa Rica (Van Patten). 
This insect, of which numerous additional specimens have been received, differs 
constantly from @. chevrolati in the fine, uniform punctuation of the elytral striz: in 
. chevrolati the punctures become very coarse, deep, and partly confluent towards the 
sides. The sexual characters are similar in both species. In Guatemala &. similis 
appears to be confined to the Pacific, @. chevrolati to the Atlantic slope. |

To the localities given, add :—Muxico, Temax in North Yucatan (Gaumer).

GLYPTOTUS (p. 113). 
2. Glyptotus yucatanus. 
Black or pitchy-brown, shining. Head sparsely, minutely punctate, the eyes prominent; prothorax transversely 
convex, much broader than long, very little wider at the base than at the apex, the sides rounded ante- 
riorly, slightly converging and feebly sinuate behind, the base bisinuate and deeply grooved within, the 
anterior angles strongly deflexed and obtuse, the hind angles acute, the surface very minutely, shallowly, 
sparsely punctate, the disc sometimes with traces of an impressed median line; elytra with regular rows 
of not very closely placed, coarse, deep punctures, which become finer towards the apex, the interstices 
smooth, flat; beneath almost smooth, the ventral surface finely, longitudinally wrinkled ; prosternum 
abruptly declivous behind; legs sparsely punctured, shining. 
Length 11-134, breadth 43-53 millim. 
Hab. Mexico, 'Temax in North Yucatan (Gauwmer). 
Numerous examples. This species has the thorax more rounded at the sides than in 
the closely allied G. nitidus and G. cribratus, distinctly narrowed behind, and almost 
smooth ; the elytra are punctured almost as coarsely as in G. cribratus, without trace 
of striz. 
ISICERDES (p. 113). 
1(a). Isicerdes vicinus. 
Black or pitchy-brown, shining. Head finely and closely punctured, the punctures coarser between the eyes ; 
antenns with the basal joints more or less rufous; prothorax transversely convex, much broader than 
long, sharply margined, the sides rounded anteriorly and sinuate behind, the anterior angles prominent 
but obtuse, the base strongly bisinuate, the hind angles sharp, the surface finely, rather sparsely punctate ; 
elytra with regular rows of coarse punctures placed upon almost obsolete Strie, the punctures becoming
