T. mvrertexTa. (General characters of T. ixtricata. Frontal base obtusely 
impressed, basal angles of the pronotum rectangular; humeral angies obtusely 
rounded; abdomen sub-opaque, punctures indistinct. 5 lines long. 
California, Joshua Child. 
Distinguished from T. tztricata by being more slender, by having the protho- 
rax more transverse, with the sides more sinuous, the antenn@ a little longer, a 
deeper emargination at the base of the elytra and prothorax, the punctures of the 
elytra more ru.ose, and the opacity of the abdomen, and less distinctness of its 
punctures. 
BeLostoma ImprEssuM Hald. Variegated dark and pale brown, neurations of 
the elytra varied with black, with a black stigma at the medial point where they 
cross. Head short, pronotum sinuous at base, sides sub-sinuous, transverse line 
rectilinear and obtusely impressed, a fovea in front of it on each side. Two 
fovez forming conjointly a V-shaped medial mark at the apex of the pronotum. 
Scutel with two quadrangles of raised lines, one on each side, the raised dorsal 
line being common to the two. Inferior surface flavous, mottled with. pale 
brown. Medial and posterior femora and tibiz with three dark bands; anterior 
femora robust. simple, the down confined to the anterior margin; caudal appen- 
dages not protruded. 23 lines long, 9 wide. 
California, Joshua Child. 
Allied to B. haldemanum Leidy, but distinguished by the dorsal impressions, 
the lighter color of the inferior surface, and the comparative narrowness of the 
posterior tibie and tarsi. 
ZAITHA INDENTATA Hald. Broadly oval, depressed, dark brown, finely sca- 
brous. Head, pronotum and scutel with indistinet patches of very short prostrate 
flavous hair. Pronotum pyramidal, lateral and anterior margin with an im- 
pressed Jine; apex sinuous, apical angle obtusely rounded, sides rectilinear, 
base sub-rectilinear, dorsal line raised posteriorly, and impressed anteriorly, 
transverse posterior line distinctly impressed, portion posterior to it, and ante- 
rior portion of the scutel, transversely rugulose; a well impressed fovea (having 
a raised margin) on each side equidistant between the dorsal line and exterior 
and anterior margins, a second shallow fovea on each side of the dorsal line 
anteriorly, conjointly forming a V-shaped figure. Disc of the scutel with irre- 
gular ruge radiating backwards and outwards, medial line impressed. Elytra 
with distinct cupreous reflexions, neurations very distinct. Feet with lines of 
silky hair, their surface and the inferior parts of the body covered with short 
prostrate hair. Length 15, width 8 lines. 
California, Dr. Le Conte. 
A second specimen has two longitudinal flavous lines on each side of the base. 
The latter is a female, and the posterior part of the body above is covered 
with ova. 
Distinguished from Z. bifoveata Hald. Stansbury’s Expedition, 370, tab. 10, 
fig. 1, by its darker color, broader form, and the greater distinctness of the fovex 
on the pronotum. 
Puatancopsis scaprives Hald. Flavous mottled with black, especially upon 
the posterior margin of all the segments, knee joints of all the feet and base of 
the antenne, brown. Upper extremity of the femora strongly curved inwards 
toward the base; externally and above regularly reticulate with blackish, and 
scabrous with raised points, which are mostly confined to the dark portions; 
under margin with a row of small spines enlarging posteriorly. Length § 11 
lines, antenne 48, posterior femora 11, tibie 124, tarsi 44. One specimen taken 
at Selma, Alabama, by Dr. Hendree. 
Resembles Ph. Jaepidicola Burmeister, and gractlipes Hald. (Am. Assoc. 1849, 
p- 336,) in size, but differs from the former by the smaller femoral spines, and 
from the latter by the scabrous femora. : 
Xya mixta Hald. Shining flavous variegated with brown. Antenne brown, 
head flavons punctate, more sparsely above, labrum and a large frontal macula 
black. Prothorax small and transverse. Elytra flavous, base and apex brown,
