Schwarz.] 364 [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 
fascize composed of fulvous hairs bordered anteriorly with white ; humeral 
and marginal carina as in B. 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 emarginate in the male; broadly 
rounded in the 9, less broadly in the §‘; anus very finely pectinate. 
Length 4.5-5 mm.; .18-.20 inch. 
Widely distributed in Florida and not rare; lives on 
Quereus 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 czeruleus, 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. 
3 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. 
QO 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. /evigatus; 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 & of 
P. levigatus. In P. purpureus the last ventral segment of 
the & has a similar impression but the two processes are 
more separated from each other and each terminates in three 
teeth. 
21. Temmnopsophus impressus n. sp.—Black, shining ; head pic- 
eous or piceous-red, finely alutaceous and sparsely punctulate with a fine 
median line on the vertex, antennz two-thirds as long the body, piceous- 
red at base. Thorax almost longer than wide in front, strongly convex,
