CLCEOTUS. 121 



4. Cloeotus plicatus. 



Acanthocerus plicatus, Erichs. in Germ. Zeitschr. fur Ent. iv. p. 143 \ 



Eab. Guatemala, Zapote, Panzos (Champion). — South America, Para 1 , Amazons 

 (coll. Bates). 



The short, erect, subclavate bristles which clothe the surface of this species are some- 

 times wanting, probably from abrasion. 



5. Cloeotus infantulus. 



Parvus, fere globularis, seneus, politus, interdum fulvo translucens ; capite sat dense punctato, clypeo late rotun- 

 dato, margine prope genas leviter sinuato, genis haud lobatis ; thorace angulis posticis valde obtusis, integriter 

 marginato, lineolis curvatis haud profundis sat dense impressis, callis quatuor politissimis ; scutello laevi, basi 

 tantum sparsim punctulato ; elytris rotundatis, margine versus humeros serrato, subtiliter striato-punctatis, 

 punctis elongatis, stria suturali versus apicem sulciformi, ibique interstitiis tribus alternis obtuse carinatis, 

 carina exteriore fere usque ad humeros extensa ; tibiis posticis extus longitudinaliter dense striatis, apice 

 extus productis. 



Long. 2-2§ millim. 



Eab. Guatemala, Zapote (Champion). A large series of examples. 



Var. Saturate olivaceo-seneus sculpturaque paullo grossiore. 



Eab. Guatemala, Cerro Zunil, Las Mercedes, Zapote, Capetillo (Champion). 



Distinguished by the apical area of the elytra being marked by three long carina?. 

 The humeral callus is very prominent, and there is an elongated polished callus along 

 the dilated lateral margin. 



6. ClCBOtUS sinuatUS. (Tab. VII. figg. 21 ; 21 a, profile of unextended specimen.) 



Kotundatus, politus, nigro-seneus, saturate aeneus, seneo-cupreus vel laete rufo-cupreus ; clypeo obtuse rotundato, 

 apice depresso et plus minusve emarginato ; thorace angulis posticis distinctis, sed apice plus minusve 

 rotundatis; scutello basi (rarissime postice) punctato; elytris usque ad basin striato-punctatis, punctis 

 parum elongatis, margine prope humeros subtiliter serratis, apice depressis multituberculatis ibique inter- 

 stitio 2° bi- vel tri-tuberculato (tuberculis raro connexis), carina submarginali elongata acuta apice hamata 

 (in var. 0. sejuncto simplici), cannula brevi apud interstitium 10 m ; tibiis posticis extus longitudinaliter 

 strigosis, apice plerurnque laevibus vel dimidio apicali lsevi punctato. 



Long. 4 millim. 



Eab. Mexico, Cordova (Salle), Jalapa (Edge) ; British Honduras, Belize (Blan- 

 caneaux) ; Guatemala, Las Mercedes, Cerro Zunil, Capetillo, Calderas, Duefias, Senahu, 

 San Juan in Vera Paz (Champion). 



This apparently common Central-American species varies much in colour and 

 sculpture both of surface and of the flattened outer side of the posterior tibiae, and 

 rather less so in the tuberculation of the apical area of the elytra. In all its varieties 

 it is distinguished by the broad, but very shallow, sinuation of the clypeus. As to 

 colour-variation, the brilliant red-coppery examples seem to be almost confined to
