rior angle is another similar tubercie. The elytra are coarsely punctured, 
slightly truncate, but not armed at tip; they have each four small polished lines 
associated by pairs, but not united, the outer basal one is very small; the inner 
one of the posterior pair, which is placed about the middle, is smaller than the 
outer. 
PuysocnemMuM Hald. 
P.amethystinum, nigrum, thorace transverso, lateribus valde rotun- 
datis, basi brevissime tubulato, disco confluenter punctato, irregulariter calloso, 
elytris late violaceis, nitidis, confertim punctatis, femoribus non clavatis. 
Long. °75. 
This species has a general resemblance in appearance to P. Proteus, but differs 
from all the species known to me in having the anterior as well as the posterior 
thighs simple; the thorax is narrowed in front, rounded on the sides, suddenly 
narrowed towards the base, which is slightly tubulate; the sides are very 
densely and confluently punctured, the disc less densely so, with three indistinct 
smooth longitudinal elevations. The elytra are shining violet blue, finely and 
densely punctured, the punctures becoming larger and less dense towards the 
base. 
One specimen was found at Sacramento, California, by Mr. J. Childs, and 
given me by Mr. Rathvon. 
A Callidium from the same collection is very similar to the female of C. an- 
tennatum, but the thorax is more densely punctured; I can otherwise discover 
no difference. 
Cacopiia Lec. 
Having, since the publication of my essay on Longicornia, obtained, through 
the kindness of Mr. Haldeman, the original specimen of his Saperda pullata, | 
have convinced myself that it must be referred to this genus, proposed by me in 
the Journal of the Academy (New Ser. 2, 149.) The following diagnoses will 
enable the two species at once to be distinguished : 
1. C. pullata, fusco-testacea, brevissime densius sordide pubescens, thorace 
parce punctato, linea dorsali postice glabra, elytris thorace latioribus cylin- 
dricis parce minus distincte punctatis. Long. -68.

2. C. pruinosa, testacea, brevissime cinereo pubescens, thorace obscu- 
riore, sat dense punctato, linea dorsali postica glabra, elytris thorace latioribus, 
cylindricis, distinctius parce punctatis. Long. °47.

Monitema Say. 
1. M.armatum, elongatum, nigrum, thorace levi, lateribus acute spinosis, 
apice et basi punctis marginato, elytris subrugosis, parce grosse punctatis, apice 
lavibus, dorso convexis, lateribus subito declivibus. Long. 1-25. 
Mexican Boundary, collected as before mentioned. This species is similar to 
M.semipunctatum Lec. (Journ. Acad. Nat. Sc. 2, 2, 167,) but the form is 
more elongate, the thorax is smooth on the disc, and the elytra are more punc- 
tured and rugous. 
2. M.crassum, breviusculum, nigrum, thorace lateribus subtuberculato, 
disco opaco parce punctato, margine postico punctato, elytris convexis, subru- 
osis minus dense variolosis, apice levibus. Long. :8. 
With the preceding. This species is similar to M. annulatum Say, but is 
stouter in its form. The elytra are much more coarsely punctured, the punc- 
tures extend further along the epipleure and suture, than along the disc; the 
elytra are very convex, the sides descend more abruptly than in M. annulatum, 
but less so than in M. armatum.
