442, ADIMERID 2. 
chink from the end of the side-piece; the acetabula, though really open, thus appear 
closed except from a certain point of view, there being almost an overlapping of the 
edge of the side-piece by the angle of the prosternal process. Mesosternum nearly as 
long as the short metasternum. Middle coxe globose, slightly separated; hind coxe 
moderately large, forming between them a slight emargination for the reception of the 
abdominal process. Abdomen with five subequal ventral segments, separated by very 
deep sutures as in many Colydiide. Body wingless. Elytra soldered. 
The body is covered everywhere with an incrustation, which, being mixed with the 
setosity of the surface, quite obscures the sculpture and structure. | 
The structure of the foot (Tab. XIV. figg. 3, 3a) is not only of great interest from 
certain speculative points of view, but seems to me to necessitate the isolation of these 
insects from the Colydiide, in the whole of which family the tarsi are quite simple and 
undilated. In some of the Colydiide the basal joint of what should be a four-jointed 
foot is not present, whereas it is this joint that is enlarged to an unusual extent in the 
Adimeridee. 
This genus occurs in South as well as in Central America, as I have in my collection 
some species of the genus from Brazil. 
1. Adimerus crispatus, sp.n. (Tab. XIV. figg. 8, 3a, tarsus.) 
Angustus, fusco-ferrugineus, rugosus, setis curvatis ornatus; elytris nigro-maculatis, antrorsum angus- 
tioribus.

Long. 27-23 millim. 
Hab. Guatemata, Senahu (Champion). 
Two basal joints of antenne thick and very squamose, the first much concealed, 
the club small, black. ‘Thorax as long as broad, slightly narrowed behind, transversely 
convex, serrate at the sides, the front angles minutely acute. Elytra very convex trans- 
versely, slightly curvate at the sides, so as to be distinctly a little narrower towards the 
shoulder, very coarsely sculptured, the sculpture consisting of very large and deep 
closely placed punctures; the second interstice costate; the colour ferruginous, with a 
large black spot just about the middle; the whole of the surface much encrusted, so as 
to conceal the colour and sculpture. Tibie angularly dilated externally about the 
middle. 
Mr. Champion procured about thirty examples of this curious little insect. They 
vary but little. 
2. Adimerus setosus, sp. n. (Tab. XIV. fig. 4.) 
Subparallelus, fusco-ferrugineus, rugosus, setis crassis ornatus ; elytris nigro-variegatis, suboblongis. 
Long. 24 millim. 
Hab, Guatema.a, San Juan, Cerro Zunil (Champion); Panama, Volcan de Chiriqui 
2500 to 4000 feet, Pefia Blanca 3000 to 4000 feet (Champion).
