184 MALACODERMATA. | 
Mr. Bates on the Amazons, The first of the two species now recorded is one of 
Mr. Champion’s most interesting discoveries in this family. 
1. Pyticera championi. (Tab. IX. fig. 10.) | 
Flavo-testacea, subnitida, subtiliter pubescens; capite, antennis, tibiis, tarsis elytrisque postice nigro-fumosis, 
abdomine piceo, Long. 9-10 millim. 
Hab. Guatemata, San Gerdénuimo (Champion). 
The intermediate joints of the antenne are together about equal in length to the 
basal joint; the first of the three terminal ones equals all preceding it; and the two 
following are successively longer, so that the whole antenna is more than half the body’s 
length. The palpi are all hatchet-shaped at the tips; but the terminal joints are not 
widely triangular, but only a little expanded. They are yellow, excepting the apical 
joints. The mandibles are acutely toothed, pitchy, the head being a little flavous about 
their bases. The thorax is almost smooth, but not very shining; the sides are nearly 
straight, fringed with soft yellow hairs. The elytra are yellow at their base, this colour 
extending down the margins and suture, while the black of the apical half extends 
indefinitely up their centre. They are closely and obsoletely punctured ; their lateral 
margins rather expanded. The metasternum and abdomen are pitchy and shining, 
paler at their margins. 
Five specimens are all Mr. Champion has sent of this novelty. 
2. Pyticera militaris. 
Pelonium militare, Chevr. Rev. et Mag. Zool. 1874, p. 73°. 
Enoplium humerale, Horn, Trans. Amer. Ent. Soc. 1867, p. 185°. 
Hab. Unrrep States, New Mexico ?.—Mexico, Jolos! (Saldé). 
The very short funiculus, apparently ten-jointed antenne, and absence of lateral 
tubercles to the thorax, bring this better into the present genus than into Pelonium. 
It is not an Enoplium, for four joints of the tarsi are easily seen from above; and I 
think it better not to adopt Dr. Horn’s name, because there is already a Pelonium 
humerale, Spin. The first two joints of the club of the antenne have their inner sides 
produced into long rami, the branch being equal in length to the rest of the joint. It 
thus and in some other respects approaches P. pilosum, Forst.; but the shortened 
intermediate antennal joints render it even more difficult to retain it than that species 
in Pelonium. The type specimen in Sallé’s collection, which has now passed into the 
possession of Messrs. Godman and Salvin, is the only one we have seen. 
ORTHOPLEURA. 
Orthopleura, Spinola, Mon. ii. p. 80; Lac. Gen. Col. iv. p. 482. 
The antenne are eleven-jointed, the intermediate joints shortened and hairy on their 
inner side; the body is cylindric, and the thorax is also cylindric but with margined
