Schwarz.] 304 [Feb 1 
behind the middle with a broad fascia of dense whitish pubescence, with 
only a few fulvous hairs intermixed; behind this with two other undulated 
fascix composed of fulvous hairs bordered anteriorly with white ; humeral 
and marginal carina as in D. ovata. Fissure of prosternum not reaching 
the hind margin, but leaving a comparatively broad margin intact, apex of 
metasternum in the middle suddenly and deeply emarginate. Last ventral 
segment with the usual marginal sulcus, not emarginatein the male; broadly 
rounded in the Y, less broadly in the f; anus very finely pectinate. 
Length 4.5-5 mm.; .18-.20 inch. 
` Widely distributed in Florida and not rare; lives on 
Quercus virens. In B. ovata and tesselata the undivided por- 
tion of the prosternum is very narrow and the metasternum 
is broadly triangularly emarginate in front. 
20. Pachyscelus caeruleus, n. sp.—Short ovate, black, head and 
thorax bluish-black or black with eneous tinge, scutellum and elytra bright 
blue, shining. Head deeply channeled, alutaceous, obsoletely punctulate, 
thorax without lateral depression and with sparse shallow punctures almost 
obliterated on the disc, more obvious at the sides, finely alutaceous at the 
sides. Elytra with a deep impression at the sides before the middle, and 
with another obsolete one near the suture behind the middle, plainly punc- 
tured, with traces of regular rows on the disc. Length 2-3 mm. ; .08-.12 
inch. 
cf Last ventral segment with an oblong impression at apex, apical mar- 
gin produced in the middle into two prominent processes each of which 
terminates in four small teeth. 
9? Last ventral segment not impressed, apical margin produced in the 
middle in an acute point. 
Very abundant everywhere in Florida. In form and size 
this species resembles P. levigatus; the elytra are however 
less triangular and more rounded at the sides; it differs also 
by its color and by the thorax not being impressed at the 
sides. Very probably there will also be a difference in the 
sexual characters of the males but I have not seen the f of 
P. levigatus. In P. purpureus the last ventral segment of 
the Y has a similar impression but the two processes are 
more separated from each other and each terminates in three 
teeth. 
21. Temnopsophus impressus n. sp.—Black, shining ; head pic- 
eous or piceous-red, finely alutaceous and sparsely punctulate with a fine 
median line on the vertex, antennee two-thirds as long the body, piceous- 
red at base. "Thorax almost longer than wide in front, strongly convex,

transversely depressed before the base, strongly rounded at apex and pro- 
duced in the middle, at the sides rounded anteriorly, towards the base 
narrowed and subsinuate; base distinctly emarginate and finely margined ; 
surface piceous or piceous-red, smooth in the middle, finely alutaceous and 
obsoletely punctulate towards the sides. Scutellum semicircular, opaque. 
Elytra elongate-oval, widened behind, basal third strongly depressed and 
transversely impressed, apical two-thirds ventricose, convex, sides sinuate 
in front of middle; color black with a large yellow marginal spot behind 
the humerus, base frequently piceous-red ; depressed part coarsely, densely, 
ventricose part sparsely punctured, each puncture bearing a short whitish 
hair. Legs piceous-black or piceous-red, hind tibie slender, slightly 
curved. Length 2-2.5 mm. ; .08—.10 inch. 
cf Sides of head in front of eyes straight, convergent anteriorly, anten- 
ne with the first joint formed as in the Z of T. bimaculatus, elytra 
more elongate, less ventricose behind. 
9 Sides of head rounded anteriorly, first joint of antenne not dilated, 
a little longer than the two following together, elytra strongly convex and 
ventricose behind. 
Eight specimens are before me, found on the meadows 
north of Lake Ashby, Volusia county, in June. 
The yellow humeral spot extends sometimes so as to nearly 
reach the suture. 
Easily known from T. bimaculatus by the form of the elytra. 
22. Eupactus viticola, n. sp.—Piceous or piceous-red, glabrous, 
shining. Head distinctly punctulate, frontal lines before the eyes, and 
transverse suture evident; clypeus opaque, rugosely punctulate ; eyes not 
prominent, moderately coarsely granulated. Antenne piceous-red ; first 
joint large, shining, punctulate, strongly curved, narrowed towards the 
extremity ; second joint as wide as the first, as long as wide, not curved in- 
wards ; joint 3 as large as joint 2, triangular; joints 4, 6 and 8 very small, 
strongly transverse ; joints 5 and 7 a little larger, strongly transverse, and 
produced inwards ; last three joints strongly compressed, the 9th twice as 
long as wide, as long as 2-8 together, and as long as 10 and 11 together, 
outer margin straight, inner margin convex, inner front angle somewhat 
produced, inner basal angle rounded ; joint 10 longer than wide, truncate 
at tip outer margin straight, inner margin strongly sinuate at the basal 
half; joint 11 closely applied to the 10th, as long as wide, rounded at tip ; 
maxillary palpi with the last joint large, triangular. Thorax anteriorly a 
little wider than long in the middle, very convex transversely, apical 
margin slightly produced at middle, and feebly sinuate each side, sides 
straight, strongly convergent in front, base lobed at middle, feebly sinuate 
each side; front angles strongly deflexed, acute, but not prominent, hind 
angles obtuse, rounded ; finely, sparsely punctulate, more densely towards 
the anterior angles, and with an impressed marginal line at the sides. Scu-
