PHALACRUS. | 247 
8. Phalacrus obscurus, sp. n. 
Ovalis, convexus, niger, minus nitidus, pedibus piceis, antennis rufis, clava obscuriore. 
Long. 3 millim. 
Hab. Mexico, Saltillo in Coahuila (Dr. Palmer), Santa Clara in Chihuahua, Mexico 
city, Acapulco (Hége), Guanajuato (Sallé), Cuernavaca (Hoge, H. H. Smith). 
This is very closely allied to P. rufipes, but is larger, and has darker legs and 
antennz, and the thorax has the scutellar lobe distinctly margined behind. Hight 
specimens. The typical examples have the mandibles porrect and largely exposed ; but 
I include also in the species some specimens in which the mandibles are entirely 
concealed beneath the clypeus, as it is possible this distinction may be merely sexual. 
4, Phalacrus germanus, sp. n. 
Breviter ovalis, minus convexus, niger, minus nitidus, pedibus piceis, antennis testaceis, clava obscuriore. 
Long. 24 millim. 
Hab. GuateMata, Quezaltenango 7800 feet (Champion). 
Closely allied to P. rufipes and P. obscurus, but less convex than either of them. 
The thorax is not margined at the base. The form of the antenne is similar to that 
of the two allied species. 
5. Phalacrus flavicornis, sp. n. 
Breviter ovalis, minus convexus, niger, minus nitidus, antennis flavis, pedibus piceis, tibiis tarsisque testaceis. 
Long. 2 millim. 
Hab. Guatemata, Capetillo (Champion). 
This is much smaller than P. rufipes; it is also less convex and has the femora dark, 
and the club of the antenna is more slender, so that I consider it distinct, though I 
have seen only one specimen. 
6. Phalacrus scutellaris, sp.n. (Tab. VII. fig. 19.) 
Breviter ovalis, latus, minus convexus, rufus, antennis pedibusque rufo-testaceis, thorace piceo, latera versus 
dilutiore, elytris plaga scutellari aliaque laterali nigricantibus. 
Long. 24 millim. 
Hab. Guaremata, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne clear, pallid red; club elongate, the terminal joint quite twice as long as the 
tenth. Thorax picescent in the centre, more dilute towards the sides, with a very 
broad short basal lobe in the middle, which is not at all margined behind. Elytra red, 
the scutellum and a large patch round it, and an elongate vitta within the lateral 
margin, black; there is no sutural stria, and the sculpture is obsolete, but consists of 
numerous punctures, transverse rather than round in form, placed on the posterior part. 
Four examples were obtained of this very distinct species.
