of the tibiae is narrow-oblong, and subacuminated at the upper (outer) end. The hind 

 tibiae are much more triangular and broader at the apex than in C. infantulus. 



8. Cloeotus excisus. 



Parvus, rotundus, nigro- vel piceo-aeneus, politus ; capite thoraceque lsevibus, hoc lateribus tantum subtiliter 

 punctatis, angulis posticis rotundafcis ; clypeo apice emarginato et leviter bidentato ; scutello lsevi (interdum 

 basi punctulato) ; elytris lineatim subtiliter punctulatis, apice haud tuberculatis, stria suturali apice sulci- 

 formi, interstitiis 1° et 2° valde convexis, Iambus ; tibiis posticis longitudinaliter striatis, nitidis, apice 

 mediocriter prolongatis, truncatura anguste ovata. 



Long, vix 3 millim. 



Hah. Guatemala, Senahu (Champion). About a score examples. 



Var. Capite thoracis disco scutelloque basi punctulatis. 



Sal. Mexico, Cordova (Salle). 



Similar in form and closely allied to C. sinuatus, var. sejunctus ; but much smaller, 

 and distinguished by its perfectly smooth and polished head, disc of thorax, and 

 scutellum, as well as by the absence of distinct tubercles from the apex of the elytra. 

 The apex of the clypeus is distinctly emarginated, and a small broad tooth is perceptible 

 on each side of the emargination. The thorax is finely margined throughout, the hind 

 angles imperceptible, and the flattened sides marked pretty uniformly with fine curved 

 scratches. The elytra have the long submarginal carina and the short inner carina 

 on the tenth interstice fine and very little elevated ; there is no tubercle or carina in 

 the apical area, the sutural stria is deep and broad, and the interstices on each side 

 are equally elevated, straight, and smooth ; the margin near the base is finely serrated. 

 The hindmost tibiae are moderately prolonged at the apex, and their outer surface is 

 marked with a few longitudinal striae ; the apical truncation is rather narrow. 



The var. from Mexico agrees precisely with the numerous Senahu examples, except 

 in the fine punctuation of the head, thorax, and base of the scutellum. 



9. Cloeotus bidens. (Tab. VII. fig. 22.) 



Rotundatus, seneus, politissimus ; capite subsparsim punctato, clypeo late triangulari apice paullo producto, 

 anguste emarginato et breviter bidentato, castero margine flexuoso : tborace sparsissinie, intra latera 

 grossius et arcuatim, punctulato, integriter marginato, stria a margine antico passim distante, angulis 

 posticis rotundatis ; scutello laevi ; elytris a bumeris gradatim sed late ampliatis, margine ampliato 

 convexo, striato-punctatis, stria suturali versus apicem sulciformi ibique interstitiis utrinque convexis 

 et rectis, area apicali alternatim carinata, carina submarginali antice abbreviata; tibiis posticis extus 

 suboblique strigosis, apice productis et compressis. 



Long. 3-4| millim. 



Hab. Panama, Bugaba (Champion). — South Amekica, Amazons. 



Distinguished from the numerous allied species of similar form and colour by the 

 shape of the clypeus, its flexuous margin, and slightly bidentate apex. The sculpture 

 of the apex of the elytra resembles that of the much smaller C. excisus in the straight
