CYCLOCEPHALA. 301 



5. Cyclocephala microspila. (Tab. XVII. fig. 18, s .) 



C. sticticce valde affinis ; minor, flavo-testacea, vertice elytris utrinque maculis duabus (interdum tribus) parvis 

 nigris, tborace immaculato vel maculis 2 aut 4 vagis ; clypeo subtiliter undulato-striguloso et punctulato, 

 apice latius et distinctius sinuato, f ronte disperse sequaliter punctata ; tborace rotundato-quadrato, lateribus 

 minus arcuatis, subtiliter disperse, versus latera parum grossius, punctato ; elytris subtiliter punctulatis, 

 breviter sparsim setosis. Pygidium S valde convexum, punctatum et breviter setosum ; 5 longitudinaliter 

 subcarinatum, convexum, fere lseve. Tarsi ungue majore integro. 2 • Elytra mox pone medium alte callosa 

 et margine verticaliter arcuato, post callum depressa. 



Long. 14-16 millim. 



Hab. Panama, Bugaba, David (Champion). 



The hind tarsi, as in the foregoing species, are very long, and in both sexes finely 

 ciliated beneath. When there are only two elytral spots present (the most frequent case) 

 it is the inner of the anterior pair that is deficient ; sometimes the spots are very minute. 



6. Cyclocephala fasciolata. (Tab. XVII. fig. 19, s .) 



Oblonga, subconvexa, nigra, nitida, elytris (interdum partim opacis) macula irregulari transversa discoidali rufa 

 vel toto nigris ; capite disperse umbilicato-punctulato, clypeo sat elongato subquadrato antice rotundato ; 

 thorace sicut in O. fuliginea, sat elongato lateribus rotundatis (angulis posticis valde obtusis, anticis pro- 

 longatis acutis), sed differt basi integriter marginato et dorso distincte disperse punctato ; elytris vage 

 striato-punctatis, stria suturali baud impressa interstitioque suturali usque ad apicem lato lsevique. Subtus 

 cum pedibus rufo-hirta. MandibulaB apice truncatse, extus breviter dentatce et intus bifidae. Prosternum 

 ante coxas valde convexum, rufo-birtum. 



c? . TibiaB anticse bidentatee ; pygidium rufo-birtum. Tarsi postici quam tibise multo longiores, articulis l°-4m 

 subtus rufo-ciliatis. 



5 . Tibise anticge tridentatse. Pygidium fere glabrum, politum. Elytra margine laterali fortiter callosa. 



Long. 20-23 millim. 



Hab. Mexico, Toxpam, Cordova (Salle), Jalapa (Hbge) ; Panama, Volcan de Chiriqui 

 4000 to 6000 feet (Champion, Trotsch). 



An example from Toxpam is figured. 



7. Cyclocephala fuliginea. (Tab. XVII. fig. 20, s .) 



Cyclocephala fuliginea, Burm. Handb. der Ent. v. p. 42 1 . 



Hab. Mexico (Salle) ; Guatemala, Capetillo (Champion).— South America, Venezuela, 

 Brazil 1 . 



Differs from the other species of the section in the maxillary lobe being short and 

 subquadrate in form, and armed on its inner apex with two teeth, and in the narrower 

 and more divergent lobes of the ligula. 



A Mexican specimen is figured. 



II. Clypeus elongatus, semiovatus ; ligula medio anguste incisa mentoque apice integro. 



8. Cyclocephala complanata. (Tab. XVII. fig. 21, <s .)
