PHANONOTUM. 99 
The individuals of this species are of larger size, and of slightly more elongate form, 
than is the case with the other allies in Mexico and Central America, and, in addition 
to this, the greater development of the pubescence on the tarsi is characteristic. There 
is no trace of infuscation of the club of the antenna; the punctuation of the head is 
- fine and distant—if any difference, even more fine and distant than those of the thorax; 
the red coloration at the extremity of the wing-case consists of a transverse margin, 
extending forwards halfway or more to the shoulder, becoming gradually indistinct 
in front. 
4. Phzenonotum collare. 
Rotundato-ovale, nigrum, nitidissimum, prothoracis marginibus picescentibus, subtus piceum, capite dilutiore, 
pedibus piceo-rufis; tarsis, palpis antennarumque basi testaceis, harum clava fusco-testacea, tarsis subtus 
sat conspicue hirsutis; capite subtiliter sparsim, elytris sat crebre et fortiter punctatis; prothorace valde 
transverso, sublevigato, tantum subtilissime distanter punctato. 
Long. 12, lat. 13 lin. 
Hab. Nicaracua, Chontales (Janson).

Hab. Guatemata, El Tumbador, 2500 feet (Champion). 
- This species approximates in form to P. tarsale, and is in fact equally allied to it 
and to P. levicolle; it is readily distinguished from the former by its shorter and less 
punctate thorax and the infuscate club of the antenna, as well as by other less conspi- 
cuous characters, while from P. /evicolle it differs by its larger size and less rotund 
form, as well as by the more hirsute tarsi. All the individuals before me agree in 
having the pale yellow labrum more exserted than in the other species; but this 
character may prove to be of no importance. The single individual found by 
Mr. Champion is a variety rather smaller in size and of darker colour, with the thorax 
slightly less abbreviate and more punctate. Additional specimens are needed to justify 
its treatment as a distinct species. 
5. Phenonotum levicolle. 
Rotundato-ovale, convexum, nigrum, nitidissimum, prothoracis marginibus elytrorumque margine apicali 
picescentibus, corpore subtus piceo, pedibus rufis, tarsis dilutioribus ; antennis palpisque testaceis, ilarum 
clava fusco-testacea; capite parce subtiliter punctato; prothorace valde transverso, fere impunctato, 
elytris crebre fortiter punctatis. 
Long. 13, lat. 3 lin. 
Hab. Mexico, Cordova, Vera Cruz (Sallé); GuatemaLa, Cubilguitz (Champion); 
Nicaragua, Chinandega, Managua (Sal/é), Chontaies (Janson). 
The individuals of this species are very similar to P. dubiwm, but are nevertheless 
easily distinguished by the shorter thorax, the surface of which is considerably less 
punctate.
