PAZDEROMIMUS. 443 
9. Pederomimus angularius. 
Philonthus angularius, Er. Gen. et Spec. p. 477'. 
Hab. Mzxtco ! (coll. Sharp), Cerro de Plumas, Tehuacan (Hége), Cordova (Sallé). 
10. Pederomimus pectoralis. (Tab. XI. fig. 16.) 
Rufus ; capite thoraceque nigro-zneis, nitidissimis ; elytris ad apicem, abdominis postico, pectore ex parte majore, 
coxis quatuor anterioribus antennisque in medio nigris; pedibus testaceis; elytris parce fortiter 
punctatis. 
Long. 8-10 millim. 
Hab. GuatmMALA, near the city, Capetillo, El Tumbador 2500 feet, Cerro Zunil 
4000 to 5000 feet (Champion). 
This species is extremely similar to P. angularius, from which it differs by the more 
sparingly punctured elytra, by the entirely yellow legs, and by the greater extension of 
the black colour of the breast, which in P. angularius leaves the metasternum red. 
The sexual characters of the two species are similar; the males have no emargination of 
the last ventral plate, but its hind margin is less rounded than in the female, and the 
front femora bear six or eight spines on the middle beneath, while in the female but 
three or four exist. 
P. pectoralis is apparently, like P. angularius, a rare insect ; the figure is taken from 
_a male example found at Cerro Zunil. 
11. Pederomimus punctipennis. 
Testaceus ; capite thoraceque nitidissimis, illo seneo, hoc rufo cumque elytris eneo-micantibus, his nigricantibus, 
ad basin testaceis; abdominis fascia ante apicem nigra; antennis in medio fuscis; prothorace seriebus 
dorsalibus fortiter 5-punctatis; elytris fortiter profundeque punctatis. 
Long. 7 millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Antenne rather short, the three or four penultimate joints transverse. Palpi and 
mandibles yellow. Head of a very shining brassy colour, very deeply impressed on the 
middle in front, and with very coarse punctures on each side behind. ‘Thorax a good 
deal narrowed behind ; in addition to the large punctures of the discoidal series, with 
about six other punctures on each side, four of which are very large. LElytra with a 
brassy tinge, blackish behind, yellow at the base. Hind body yellow, with the two 
penultimate segments in greater part black; terminal styles blackish. 
Very similar to Belonuchus mimeticus, but readily distinguished by the brassy lustre 
of the thorax and elytra, as well as by the coarser punctures on these parts. Only two 
very immature females have been found; and as the prosternum is only indefinitely 
divided, it is quite possible that a knowledge of the male may prove the insect to be 
congeneric with B. mimeticus.
