APECHTHES.—TAPEINA. 191 
antenne are ornamented with crests and tufts of hair. One species only, from Mexico 
and Guatemala, has been as yet described ; to this Mr. Champion has added a second, 
very distinct in its markings, from Guatemala.

Group TAPEININI. 
This group, equivalent to the “ Groupe Tapeinite ” of M. Thomson, is retained, pro- 
visionally, for the anomalous genus Tapeina, the true position and affinities of which it 
is difficult to determine. M. Thomson, in his ‘Systema Cerambycidarum,’ in 1864, 
placed it at the end of the Lamiide, after the Saperdini; and in my review of the 
Longicorn Coleoptera of the Amazons, in 1866, I treated it as a separate group having 
affinity with the Desmiphorini and Exocentrini, stating that these curious insects 
appeared to be “abnormally flattened Exocentrine.” Lacordaire, in the ninth volume of 
his ‘Genera,’ in 1872, disagreeing with these views regarding their affinities, placed them as 
a Groupe Tapeinite among a series of Old-World forms, and in close connexion with Enotes 
and Enicodes, forms peculiar to New Caledonia, with which, indeed, they agree in their 
chief structural characters. I am now inclined to doubt that Tapeina has any close 
affinity with the Exocentrini, the anterior acetabular sutures being less tightly closed 
than they are in the true members of that group; and I think their true place is near 
Eupogonius and allies in the Desmiphorini.

The genus is peculiar to Tropical America. Four species are known, of which the 
following is the only one occurring in Central America.
