elytra, described as S. rubidus by Dr. Melsheimer, who, however, suspected 
that they might be the male of S. 2zger. Both sexes vary in size, the dorsal 
line is sometimes impressed in both, and the distinctness of the raised lines of 
the elytra differs in each. 
S. perropnya Knoch, 1801. N. Beitr. 181. Guér. Sp. No. 4. Rhipicera 
fulva Lap. 1834, Ann. Ent. France, 3, 3826. Rh. proserpina Newman, 1838, 
Ent. Mag. 5, 883. Male considerably smaller than the female, and with the 
elytra slightly narrowing posteriorly instead of being widest behind the middle, 
as in the female. Black, with an indistinct yellowish pubescence. Mandibles 
black, antenne dark rufous, base black ; head and pronotum finely scabrous, the 
width of the latter about double its length, sides convex, subangular behind the 
middle, dorsal line impressed or wanting. Scutel circular, minutely scabrous. 
Elytra but little wider than the prothorax, slightly tapering posteriorly, surface 
deeply and coarsely punctured in irregular longitudinal series, leaving intersti- 
tial raised lines, which are most regular between each pair of the punctured 
lines. ‘Tarsi with fulvous hair beneath, ungues reddish. Length 5 lines, elytra 
4, pronotum 1 in Jength and 1} in breadth. In case S. brevicollis Mels., 1845, 
Proc. Acad. Nat. Sc. 2, 220, is a distinct species, it will be difficult to deter- 
mine whether the male here described appertains to it or to S. petrophya. I 
think, however, that S. drevicollis has no sufficient character to separate it from 
S. petrophya. 
SaANDALUS SCABRICOLLIS Hald. @ Black, sides of the prothorax punctate 
scabrous, convex before the middle and concave behind it, so as to be slightly 
sinuous. Length 43 lines, elytra 33. Cab. Le Conte. 
The prothorax is more coarsely punctured than in S. 2/ger, (which has it 
finely punctulate) and the single specimen observed, besides its small] size, has 
the apex of the elytra slightly compressed externally in a sloping direction. 
Genus CrypropLeura Lec. Journ. Acad. 2d ser. 2, 6. 
Head small, mandibles acute, palpi with the last joint somewhat enlarging 
towards the end, eyes subreniform, antenne short and slender, 1st and 5th arti- 
culations rather longer than any of the rest. Prothorax subglobular, mesoster- 
num protuberant. Seutel rounded posteriorly. Elytra rather slender, wider 
than the prothorax, narrowing gradually towards the apex; humeri prominent, 
sides sinuate near the base. Feet weak, femora slightly incrassated towards 
the apex. 
C. crata Hald. Shining black; head, mandibles, thorax and scutel slightly 
sericeous with yellowish hair; labrum and palpi rufous, front flat, medial line 
slightly raised. Thorax finely and sparsely punctured. Elytra with fine and 
sparse piliferous punctures, apex truncate, marked each with 4 orange spots ; 
the 1st Jongitudinal, basal and medial; the 2d before the middle, and marginal; 
the 3d medial and subsutural ; and the 4th immediately behind the 3d. The 3 
latter are irregular and confluent. ‘Tibiz, tarsi and base of the femora rufous. 
8 lines long, humeri 4 wide. 
Tampico, Mexico, Lieut. H. Haldeman. 
TIMARCHA INTRICATA. Oblong convex, black, shining, scabrous with conflu- 
ent impressed punctures, which are coarsest upon the elytra. Head irregularly 
and densely punctate, front concave, with an indistinct fovea on each side; an- 
tenne with the penult articulation extending to the base of the pronotum, 
exterior articulations clothed with short brown hairs. Pronotum transverse, 
apex broadly emarginate, medial portion rectilinear; base sub-sinuate ; sides 
very convex, narrowed posteriorly, basal angles acute; surface varied with irre- 
gular shallow impressions, and densely and irregularly punctate. Secutel witha 
few punctures. El]ytra scabrous with large confluent punctures, the interstices 
irregular and finely punctate, humeral angie rectilinear and obtuse. Inferior 
surface less densely punctate, punctures of the feet fine. Less than 5 lines long.
