PSEUDOSERICA. 153 



1. Pseudoserica micans. (Tab. IX. fig. 17.) 



Philochlcenia micans, Kirsck, Berl. ent. Zeitsclir. 1885, p. 217 \ 



Hob. Panama, Volcan de Chiriqui 2500 to 4000 feet, David (Champion).— South 

 America, Ecuador 1 . 



Five examples, agreeing with Kirsch's excellent description ; but two of them only 

 are of the colour he particularizes, viz. : — "braunroth, Kopf und Halsschild dunkler." 

 The others are rich purple coppery-brown, silky on the elytra and metallic in certain 

 aspects on the thorax. 



A specimen from the Volcan de Chiriqui is figured. 



2. Pseudoserica aeruginosa. 



Philochlcenia aeruginosa, Burm. Handb. der Ent. iv. 2, p. 32 \ 

 EaJb. Nicaragua, Chontales {Belt).— South America, Colombia *. 



One example. Differs from P. micans by its brassy-brown colour, the thorax desti- 

 tute of pruinose bloom, and the punctuation much finer and closer — in all of which 

 points it agrees with Burmeister's description. 



Other closely allied species, or varieties, from Ecuador and Venezuela, are known in 

 collections. 



3. Pseudoserica setisparsa. 



Oblongo-ovata, castaneo-fusca senescens, setis reclinantibus albidis conspersa ; capite confluenter punctato ; 

 clypeo subprofunde simiato, lateribus utrinque leviter sinuatis ; tborace post medium angulatim dilatato, 

 sat crebre (cum scutello) umbilicato-punctato, marginibus lateribus crenulatis ; elytris ruguloso-punctatis, 

 substriatis ; corpore subtus lougius piloso cum pygidio dense umbilicato-punctato ; tarsis omnibus ( <S ?) 

 subtus dense pilosis, posticis articulo basali quam 2° et 3° conjunctis longiore ; tibiis anticis 3-dentatis ; 

 antennis (9-articulatis) pedibusque testaceo-rufis. 



Long. 8 millim. 



Eab. Guatemala, Zapote (Champion) ; Nicaragua, Chontales (Belt). 



Two examples only. The short whitish seta? are of uniform length on the thorax 

 and elytra, and without mixture of longer setse in rows or otherwise : all are reclined 

 backwards. Six or seven stria? on each elytron are indicated by the slight convexity 

 of the corresponding interstices *. 



* A very similar species, widely spread over tbe Amazons valley, is liable to be confounded with tbe above, 

 and may be here described in order tbat the differences of the two, and of two other common species, may be 

 pointed out : — 



Pseudoserica amazonica. 



Oblongo-ovata, cuprascenti-fulvo-fusca, interdum viridi-aeneo tincta, setulis reclinantibus (pilis sparsis multo 

 longioribus intermixtis) fulvis, thorace densius longipiloso ; capite confluenter punctato ; clypeo sub- 

 profunde sinuato, lateribus utrinque leviter sinuatis ; thorace post medium rotundato-dilatato, crebre 

 sed discrete punctulato, punctulis singulis e punctulis minoribus compositis ; elytris crebre subruguloso-
