PADEROMIMUS. 445 
15. Pederomimus maculipes. 
Capite, elytris, abdominis postico pectoreque nigris; thorace abdominisque basi rufis; antennis crassiusculis, 
flavis; pedibus albidis, femorum dimidio externo dilute nigro. 
Long. 63 millim. 
Hab. Mexico (Flohr), Cordova (Sallé), Jalapa (Hoge). 
Antenne rather stout, entirely yellow, rather thicker externally, the penultimate 
joints not quite so long as broad. Head black, only moderately broad, with numerous 
coarse punctures behind. Thorax rather slender, a good deal narrowed behind, the six 
punctures of the discoidal series and the six or seven others existing on each side large 
anddeep. Scutellum densely and coarsely punctate. Elytra not elongate, scarcely so long 
as the thorax, black, with the base red, with deep coarse punctures, which are wanting 
towards the hind margin. The three basal segments of the hind body red, and each 
with crenate sculpture on the transverse depression at its extreme base; the following 
or fourth segment in greater part black, but red at the extreme base; the penultimate 
Segment black, with the hind margin yellow; the terminal segment black, with the base 
yellow ; the segment of the armature dark. Legs very pale, with the outer portions of 
the femora broadly and definitely dark, and the apices of the tibie slightly infuscate. 
Apparently rare, only three examples having come under my observation. That which 
has served as the type for the above description is no doubt a male, though the only 
character indicating this that I can observe is an extremely slight emargination of the 
last ventral plate. The female much resembles the same sex of P. difformiceps, but 
has the head and thorax of a rather different form, and the basal joint of the hind 
foot shorter. 
16. Pederomimus difformiceps. (Tab. XI. fig. 23.) 
Angustior, rufus, nitidus ; capite, elytris (basi excepta) abdominisque postico nigris, hoc flavo-cingulato ; antennis, 
palpis pedibusque testaceis ; femoribus extrorsum pectorisque lateribus fuscis; prothorace seriebus dorsa- 
libus sat fortiter 6-punctatis ; elytris fortiter minus dense punctatis. 
Long. 73 millim. 
Mas, Capite superne postico truncato. 
Hab. GuatTEMALa, near the city, Capetillo (Champion). 
Antenne rather stout, the penultimate joint about as long as broad. Head narrow, 
with very few punctures. Thorax slender, the six punctures of the dorsal series and the 
four or five other punctures present on each side rather coarse. LElytra black, with the 
base narrowly red, coarsely punctate, shining, the punctures more scanty and less coarse 
behind, so that the hind margin is smooth. Mind body red, with the dorsal plate of 
the antepenultimate segment more or less black behind; the penultimate segment 
black, with the hind margin yellow; the terminal segment yellow at the base, black 
behind; the armature black. Legs pallid yellow, with the femora externally broadly 
dilute black ; the tibie slightly obscure at the apex.
