450 COLYDIIDA. 
ENDEITOMA, gen. nov. 
Corpus tenuiter hispidum. Antenne decem-articulate; articulo tertio elongato; articulo decimo apice pubescente. 
This genus comes between Cicones and Colobicus ; it differs from the former by the 
structure of the antenne, the third joint of which is remarkably elongate, and the club 
is not a round joint, but is of an oval shape with a pubescent apex. From Colobicus 
the genus is distinguished by the club not being distinctly divided into two joints. 
The epistome is short and undilated, and leaves the labrum uncovered. The eyes 
are free, convex, only moderately coarsely facetted. The mentum is rather large, 
transverse. ‘There are short, obscure, antennary grooves, as in Bitoma crenata. The 
cox are all very much approximated; the prosternal process is abruptly curved 
upwards, and the front acetabula are open behind. The epipleure are rather broad, 
and are continued to the apex of the elytra. The legs are simple; the tibie are desti- 
tute of spurs; the basal three joints of the tarsi are subequal in length. 
1. Endeitoma mexicana, sp.n. (Tab. XIV. fig. 9.) 
Oblonga, picea; capite prothoraceque granulatis, hoc lateribus serratis; elytris parce subtiliter hispidulis, 
crenato-striatis, interstitiis nitidulis, remote granulatis. 
Long. 43 millim. 
Hab. Mexico, Jalapa (Hoge). 
Antenne slender, sparingly setose ; first joint nearly concealed ; second rather longer 
than broad; third three or four times as long as the fourth; 4-9 moderately small, 
ninth broader than long; tenth joint oval, in larger part bare and shining, but the apex 
annulate and densely set with pubescence. Head flat, densely granulate. Thorax 
transverse, the sides parallel, serrate, the posterior angles distinct, rectangular, the sur- 
face closely granulate. Elytra with numerous series of fine crenulations ; the interstices 
broad, shining, viewed from behind appearing transversely wrinkled, and from in front 
sparingly granulate ; the sete are fine, long, erect, but scanty. 
Only one specimen has been procured of this species. The long third joint of the 
antenne distinguishes it from all the other Synchitinee yet known from our region. It 
is probable that the North-American Synchita granulata, Say, may be allied to 
EF. mexicana. 
2. Endeitoma panamensis, sp. n. (Tab. XIV. fig. 10.) 
Minor, oblonga, ferruginea ; antennis pedibusque flavis; capite prothoraceque granulatis, hoc posterius angus- 
tato, lateribus serratis; elytris subtiliter crenato-striatis, minute, parum perspicue, hispidulis. 
~ Long. 24 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne small and slender; third joint a little longer than the second ; club small.
