202 LONGICORNIA. 
According to the description, this species must be closely allied to the North-American 
T. discoideus, Lec. (Journ. Ac. Phil. ser. 4, p. 26); but Dr. Horn, in his recent revision 
of the North-American species, keeps them separate, and he has given me the result 
of his examination of Dr. Leconte’s type specimen, which confirms the view that the 
insect here cited is really the 7. umbonatus of that author. The thoracic umbo is very 
sharply elevated on the sides. The specimen figured is from Mexico. 
8. Tetraopes rubrocinereus. 
Tetraopes rubrocinereus, Thomson, Class. Long. p. 67. 
Hab. Mexico, Izucar, Oaxaca (Sallé), Jalapa (Hoge); Guatemala, San Gerdnimo, 
Guatemala city. 
Group PHYTACIINI. 
In this group I propose to include Lacordaire’s Phyteeciides vraies, Amphionychides, 
and /Erenicides, a numerous assemblage of forms in which the Saperda type of Lamiide 
reaches its highest development. The tarsal claws are nearly always fissile ; 7. e. the basal — 
tooth is long and acute; and the elytra in the more typical genera are carinated on the 
sides. Some of the species have tufted antenne; and others exhibit extraordinary | 
mimetic resemblances. 
| OBEREA. 
Oberea, Mulsant, Coléop. de France, Long., ed. 1, p. 194. 
A genus of very wide distribution, and very numerous in species, about one hundred 
having been described. Many species occur in Europe and in North America, extending 
to high latitudes ; and they abound in the Malayan and Indian regions. None, however, 
has been recorded from South America or Australia; a few have been described from 
Tropical Africa. The following is the only species as yet known from Mexico or 
Central America :— 
1. Oberea quinquepunctata. 
Flava, aureo-pubescens, elytris nigris, (epipleuris exceptis) cinereo subtiliter pubescentibus ; fronte punctis 
duobus, vertice tribus (transversim positis), thorace quinque dorsalibus, altera utrinque prope coxas 
anticas, metasterno vittula laterali, femoribus basi, tibiis tarsis et antennis nigris; elytris subtiliter 
punctulatis. 
Long. 7-8 lin. ¢ 9. 
Hab. Mexico, Capulalpam, Juquila (Sallé). 
Not dissimilar in form and colours to the North-European 0. oculata, but very much 
more finely and sparsely punctured.
