256 SUPPLEMENT. 



2. Plastococcus apicalis. 



Sanguineo-rufus, capitis basi protboraceque (basi et lateribus exceptis) indeterminate nigris ; elytris singulis 

 macula subapicali nigris, vix punctulatis. Long. 5 millim. 



Hab. Panama, San Feliz in Chiriqni {Champion). 



Larger than P. atricinctus. The mouth, antennae, palpi, and the base and sides of 

 the thorax are yellowish-red, but in a vague way, and are evidently variable in the 

 degree to which this colour extends. The elytra are more obsoletely punctulate 

 (in one example nearly smooth) ; they are entirely blood-red, except the two spots 

 near, but not quite reaching, the apex, which together form an arcuate mark nearly 

 disjoined at the suture. 



P. apicalis is evidently very nearly allied to, and perhaps only a local variety of, 

 P. atricinctus. 



Three specimens. 



BEACHYSPHENUS (p. 92). 

 24 (a). Brachysphenus sp A 



Hab. Guatemala, Coban in Vera Paz (Conradt). 



A single specimen of a Brachysphenus unknown to me. Fulvous-yellow ; the elytra 

 black, with the epipleurae, two basal spots (somewhat obliquely placed), and the apex 

 — enclosing a black spot on each elytron, these spots being united along the suture 

 and margin with an interrupted fascia, — whitish -yellow. Elytra very obsoletely 

 gemellate-striate. Antennae, knees, tibiae, and tarsi black. 



CYPHEKOTYLUS (p. 103). 

 Cypherotylus alutaceus (p. 107). 



To the Mexican locality given, add:— Amula, Omilteme, and Xucumanatlan in 

 Guerrero, 6000 to 8000 feet (H. H. Smith), Mochitlan in Guerrero (Baron). 



Sent in abundance from Guerrero. 



BBACHYLON (to follow the genus Homceotelus, p. 114). 



Corpus breve, oblongum, nitidum, glabrum ; elytra parce, haud profunde punctato-striata ; prothorax validus, 

 basi bisinuata vix marginata, lateribus tenuissime marginatis ; caput receptum. Antennae validse, decem- 

 articulatse ; clava capitulata, pubescente, triarticulata, articulis connatis segre distinctis. Pedes breves ; 

 f emoribus tibiisque compressis, baud multo dilatatis ; tarsis quadriarticulatis (?), tenuibus ; unguibus 

 simplicibus, articulo quarto longo. 



The above is the formula (so far as I have examined the two specimens) for a very 



small beetle of doubtful location, at first sight resembling a small Cercyon, but 



apparently allied to Dacne, and perhaps to Xestus of Wollaston ; but differing in the
