GEOTKUPES. 115 



10. Geotrupes onitidipes. (Tab. VII. fig. 17, s .) 



Geotrupes onitidipes (Candeze, MS.). 



Breviter ovatus, nigro-seneus, nitidus, subtus cum pedibus cyaneus, nigro hirsutus ; clypeo triangulari apice 

 obtuso, dense confluenter punctato tuberculoque obtusissime parum elevato, vertice lsevi ; antennis piceo- 

 nigris ; thorace a basi usque ad apicem paullo arcuatim angustato, lateribus solum punctato, linea dorsali 

 obsoleta, basi subtilissime marginata ; scutello lato, laevi ; elytris brevibus, profunde striatis, striis dorsa- 

 libus fere lcevibus, lateralibus (minus exaratis) punctatis, interstitiis dorsalibus valde convexis. 



<S . Tibiae anticag valde elongatse, graciles, extus dentibus 5-6 distantibus, apicali bifido ramo interiore longis- 

 simo ; subtus denticulis 3-4 parvis. 



2 • Tibiae anticse normales. 



Long. 13-16 millim. 



Hah. Guatemala (Rodriguez, in colls. Salle and Bates), Capetillo (Champion). 



I cannot find that Dr. Candeze ever described this singular species, which he 

 distributed to his correspondents many years ago under the name I have adopted. 

 Mr. Champion met with one example only, a small male. As the middle leaflet of the 

 antennal club is entire round its edge, and the apical tooth of the male anterior tibiae 

 is broad and bifid, though to an exaggerated degree, the species, I presume, would 

 belong to Jekel's subgenus Cnemotrupes. 



11. Geotrupes cavicollis. (Tab. VII. figg. 18, <$ ; IS a, side view of head and 



thorax.) 



Elongato-oblongus, niger, nitidus, subtus nigro hirsutus : antennis rufo-piceis, clava fulva ; clypeo late triangu- 

 lari, apice acuminato-reflexo, tuberculo magno conico antice carinato armato, genis angulatis et prope 

 suturam clypealem acute dentatis ; thorace transverso, lateribus tantum sparse punctato, linea dorsali 

 postice impressa et punctata, basi marginata et utrinque arcuatim emarginata, medio prope marginem 

 anticum fovea transversa sat profunda antice carina marginali delimitata ; elytris haud profunde punc- 

 tulato-striatis, interstitiis parum convexis. 



c? . Tibise anticse extus dentibus normalibus duobus deinde longo intervallo denticulis 2-3, subtus dente vel 

 spina valida armatae. Eemora postica subtus integra. 



5 . Tibias anticse extus 6-7-dentatse, subtus inermes. 



Long. 20 millim. ,5 . 



Hob. Mexico, Ciudad in Durango 8100 feet (Forrer, Hoge). 



The middle leaflet of the antennal club has part of its edge emarginated ; the species 

 therefore belongs to Jekel's Division II. It is apparently allied to the European 

 Gr. (Canthotrupes) douei, Gory, the margin of the genee, or " canthus ocularis," being 

 bidentate in the same places as in that species, though the prominences are not nearly 

 so large. The mandibles also do not present the extraordinary form they have in 

 G, douei. I assume that the two examples examined are males. 



12. Geotrupes ? 



Hah. Mexico, Eefugio in Durango (Hoge). 



A single damaged specimen of an apparently distinct species of the section Cnemo- 

 trupes.
