. Hab. Muxico, Amula in Guerrero (H. H. Smith). 
Six examples, one of which is of'a blood-red colour. 
9. Orthygia unifasciata. (Tab. XLII. fig. 10.) 
Ovate, widened posteriorly, testaceous, the apical joints of the antennw: and the breast black; thorax with a 
few punctures; elytra deeply punctate-striate, each with a narrow angulated red fascia below the 
middle. 
Length 2 lines. 
- Hab. Mexico, Amula in Guerrero (H. H. Smith). 
A single specimen. More dilated posteriorly than the preceding species; the thorax 
of similar shape, but impunctate, with the exception of three or four widely separated 
punctures on either side extending from the anterior margin downwards, the basal 
grooves indistinct ; the elytra with rows of deep punctures, the rows near the suture 
sinuate, the interstices slightly convex, and with a narrow blood-red angulated fascia 
below the middle not extending to either margin; underside (the breast excepted) and 
legs entirely testaceous. | 
SUETES. (To precede the genus Mesodera, p. 344.) 
Body narrowly elongate ; head very broad; antenne robust ; thorax strongly transverse, with.a very obsolete 
basal sulcus ; elytra punctate-striate ; posterior femora strongly incrassate ; posterior tibia 1ucronate ; 
the first joint of the posterior tarsi as long as the following two joints together ; claws appendiculate ; 
anterior coxal cavities closed; prosternum narrow, but distinct. 
6. Antenns# very robust, the two basal joints greatly thickened, the following three dilated, the other 
joints short. . 
@. Antenne gradually thickened towards the apex. 
This genus belongs to the group Crepidoderine, and is principally distinguished by 
the extraordinary development of the antennz in the male sex. The thoracic sulcus 
is scarcely visible and limited at the sides by a rather more distinct longitudinal groove. 
The single species referred to it is of small size. 
1. Suetes niger. (Tab. XLII. figg. 11, ¢ ; 11a, antenna.) 
Black, the basal joints of the antenne and the tibie and tarsi flavous; head and thorax strongly punctured ; 
elytra closely punctate-striate. 
3. The last six joints of the antennee and the femora piceous or black. 
©. Antenne, the four anterior legs, and the posterior tibiz flavous. 
Length 1 line. 
g. Head broader than long, not narrowed behind the eyes, the latter small, the vertex strongly punctured, the 
frontal tubercles obsolete, divided by a short longitudinal groove, the lower portion of the face deflexed ; 
penultimate joint of the palpi moderately thickened, the last joint acute, short; antenne extending to 
beyond the middle of the body, the lower five joints flavous, the others black, the first joint long and very 
stout, the second short, the following three joints longer and much widened, the others short, slightly 
longer than broad, laxly articulated to each other; thorax more than twice as broad.as long, the sides 
nearly straight, very narrowly margined, the anterior angles slightly thickened, the disc strongly and 
irregularly but not closely punctured, the basal sulcus scarcely perceptible; scutellum rounded at the
