COTALPA. 



Cotalpa, Burmeister, Handb. der Ent. iv. 1, p. 423 (1844) • Horn, Trans. Am. Ent. Soc. 1871, 

 p. 338. 



A genus hitherto recorded only from temperate North America; six species are 

 known, chiefly from the southern and western States. The two following have a longer 

 and more acutely rounded clypeus than in the typical species of the genus, but not 

 much more so than in C. ursina, and they differ further in the major claw of all the 

 tarsi, in the male, being cleft (unequally and narrowly) at the apex. 



1. Cotalpa nigro-asnea. (Tab. XVI. fig. 22, <s .) 



Anguste ovata, capite, thorace pygidioque viridi-aeneis, politis, elytris corpore subtus cum pedibus nigris viridi- 

 eeneo tinctis, subtus cum femoribus, pronoti marginibus et pygidio longe (pectore toto densissime) rufo- 

 villosa. Caput grosse sed discrete punctatum, punctis minutis intermixtis ; clypeo semiovato, antice 

 subacute rotundato, margine reflexo, sutura frontali paullo flexuosa ; tboraee minus transverse- (paullo 

 elongato), paullo post medium angulatim dilatato, antice rectilineatim angustato, angulis anticis acutis, 

 posticis obtusis sed distinctis, margine basali medio interrupto ; scutello sparsim punctulato ; elytris ante 

 medium perparum ampliatis (nee angulatis), epipleuris apud coxas posticas terminatis, sparsim (apud 

 strias lineatim) punctulatis, limbo posteriore rugoso-punctato et fulvo-setoso. Mesosternum inter coxas 

 anguste carinatum, nullo modo porrectum. Pygidium ( tf ) leviter convexum, subconfluenter punctulatum, 

 punctis piliferis majoribus intermixtis. J 1 . Ungues majores prope apicem fissi, parte superiore tenui 

 setiformi, breviore. 



Long. 21 millim. tf . 



Hab. Guatemala, Cerro Zunil 4000 to 5000 feet (Champion). 

 Five examples, all males. 



2. Cotalpa aurescens. (Tab. XVI. fig. 21, <? .) 



C '. nigro-cenece afflnissima; differt colore supra (clypeo obscuro excepto) laetius viridi-senea, certo situ aureo- 

 relucens, pectore, femoribus pygidioque densius et longius fulvo villosis ; occipite tboracisque margine 

 fulvo-flmbriatis. Clypeus semiovatus, sed mox a basi paullo dilatatus, margine altius elevato. Csetera 

 sicut in G. nigro-cenea. 



Long. 23 millim. tf . 



Bab. Mexico, Chiapas (Salle). 



One example only. The long and dense pale tawny villosity of the under surface, 

 pygidium, &c. is exceedingly fine and silky, differing much from the shorter and stiffer 

 rusty-red, but still very dense, hairs of C. nigro-cenea. 



PARACHRYSINA. 



Chrysina (?), Thomson, Archiv. Ent. i. p. 148 (1857).
