236 PHYTOPHAGA.—SUPPLEMENT. 
MYOCHROUS (p. 174). 
Myochrous melancholicus (p. 174). 
To the Mexican localities given, add:—Villa Lerdo in Durango, Cholula 0 in Puebla, 
Frontera in Tabasco (Hége). 
6. Myochrous carinatus. 
Obscure sneous, clothed with yellow scales; the basal five joints of the antenne fulvous; the head with two 
oblique ridges on the vertex; the thorax with three lateral teeth; elytra rather finely punctate-striate ; 
anterior tibie distinctly, the posterior femora obsoletely, toothed. 
Length 2-23 lines. 
Hab. Mexico, Toxpam (Sallé), Teapa and San Juan Bautista in Tabasco (H. #. 
Smith, Hoge). 
M. carinatus differs from all the other species of the genus known to me by the more 
or less distinct oblique ridges on the vertex of the head. The entire upper surface is, 
as usual, covered with thick yellowish scales, which often obscure the punctuation; the 
labrum and the basal five joints of the antenne are fulvous; the thorax is about as 
broad as long, but the teeth at the sides are much more distantly placed than they are 
in M. melancholicus. 
TYPOPHORUS (p. 177). 
2(a). Typophorus interstitialis. 
Bluish-black, the basal six joints of the antenne fulvous; thorax strongly rugosely punctured; elytra with a 
large pale red basal spot, strongly punctate-striate, the interstices finely punctured. 
Length 3 lines. 
Hab. Mexico, Iguala in Guerrero (Hége). 
The strongly, semirugosely, punctured head and thorax and the finely punctured 
elytral interstices distinguish this species from all others of the genus known to me. 
The red basal spot extends nearly to the middle, but not quite to the sutural margin 
of the elytra, and its posterior edge is strongly oblique; the elytra have no basal 
transverse depression, and their punctured striz are visible to the apex. The femora 
are armed with a minute tooth. A single specimen. | 
Typophorus chalceus (p. 179). 
To the Mexican localities given, add:—Acapulco in Guerrero, Tapachula in Chiapas 
(Hoge), Temax in North Yucatan (Gaumer). 
Very variable in size and punctuation, as well as in colour. T. viridicyanea (Crotch) 
seems to me to be only a blue variety of this species ; if so, Lefévre’s name cannot stand. 
Numerous specimens were obtained by Herr Hoge during his second expedition.
