234 HETEROMERA. 
Puebla (Sallé), Jalapa (Hoge); Guatumana, San Joaquin, San Gerénimo, Capetillo, 
Aceytuno, Cerro Zunil (Champion); Nicaracua, Managua (Sallé), Chontales (Belt,

Bugaba (Champion).—CotomBiA ; Boutvia!?; Braziu 2°. 
A common species throughout our region. The series of about seventy specimens before 
me vary considerably in size and in the intensity of the elytral punctuation; in very 
many examples the elytra are closely and equally punctured throughout, in others more 
shallowly and sparingly towards the apex; the elytra also vary in Jength, in most of the 
specimens from Orizaba (as in the one from Panama) they are comparatively short, in 
those from San Joaquin comparatively long: a short series from San Gerénimo are con- 
siderably smaller in size ; two from Cerro Zunil are very large, equalling the largest of 
the South-American specimens in Mr. F. Bates’s collection ; our examples vary in size 
from 63-11 millimetres. These different varieties are connected by numerous interme- 
diate forms; they cannot, in my opinion, be satisfactorily separated. The antenne are 
rather stouter in some examples; the tibie slender and unarmed in both sexes. I met 
with this insect pretty commonly in various localities, from the sea-level to an elevation 
of 5000 feet; it is found chiefly in wooded districts. 
2. Anzdus similis. 
Rather broader than A. punctatissimus ; the prothorax more constricted behind, very much more coarsely and 
sparingly punctured, the base distinctly impressed on each side just within the rather more acute hind 
angles ; the elytra still more coarsely punctured. 
Length 83-10 millim. (¢ 9.) 
Hab. Mexico, Orizaba (Hége); Guatemata, San Geronimo (Champion); Nicaragua, 
Chontales (Janson). 
Six examples, differing as above. In one of these the thorax is marked with red at 
the sides, and the elytra have an ill-defined patch of red on each side behind the middle ; 
as in A. punctatissimus, the punctuation of the elytra varies, and is coarser and closer in 
some examples. The antenne are rather longer and more slender in the male than in 
the female. An allied form is found at Ega. 
8. Anedus mexicanus. (Tab. X. fig. 17.) 
‘Oblong ovate, rather short, brownish-piceous, shining, sparingly clothed with rather long suberect hair. Head 
rather coarsely but not very closely punctured, transversely impressed in front ; eyes large; antenne 
comparatively rather short, moderately stout, ferruginous, joint 2 very short and transverse, not half the 
length of 3, joints 3 and 4 subequal, joints 5-10 slightly widening outwardly and equal in length, joint 11 
longer than 10 and narrowed at the apex; prothorax transverse, the sides rounded anteriorly, abruptly 
narrowed and sinuate behind, the anterior angles broadly rounded, the lateral margins extended and pro- 
minent, the base obliquely impressed on each side just within the produced and very acute hind angles, 
the surface sparingly, regularly, and coarsely punctured; scutellum with a few scattered fine punctures ;
