PICTINUS. 83 
4. Pictinus denticollis, n.sp. (Tab. VI. figg. 4, 9, from beneath; 5, head 
and part of the pronotum from above, ? .) 
@. Oblong-ovate, piceous, the basal half of the connexival segments obscure ochraceous, the legs and under 
surface obscure ferruginous ; the membrane smoky-black, obscurely luteous at the base. Head transverse, 
granulate ; the post-ocular portions very short, rounded, with a few short hairs; the spiniform antenni- 
ferous processes divergent; the apical process moderately long, constricted behind, slightly emarginate 
at the tip; antenne short, joint 1 extending to a little beyond the apical process of the head, 2 short, 
3 and 4 subequal in length, 3 much longer than 2, 4 piriform, pilose at the tip. Pronotum transverse, 
broad, granulate, subtruncate at the base and apex, sinuate at the sides before the middle, and narrowed 
in front; the anterior portion short, depressed, with prominent, obtuse, outwardly directed anterior angles, 
the dise with a groove down the middle and a flattened callosity on each side of it; the posterior portion 
parallel behind, obliquely narrowing in front, and with a short tooth at the middle of the outer margin. 
Scutellam carinate. Corium parallel at the base and of the same width as the pronotum, extending to 
the apex of the first segment, the nervures granulate. Abdomen rounded at the sides posteriorly ; the 
sixth segment truncate at the apex, with the outer apical angles prominent; the genital lobes moderately 
stout; the spiracles prominent, placed near or upon the outer margin, those on the first, fifth, and sixth 
segments visible from above, the first very prominent. 
Length 33, breadth 14 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Two females. In this small species the sides of the posterior portion of the pronotum 
are dilated at the middle into a short tooth, the head is transverse, with the post- 
ocular portions very short and armed with a few short hairs only, and the spiracles 
on the first segment are very prominent, projecting laterally to considerably: beyond 
the connexival margins, 
5. Pictinus quadraticeps, n. sp. (Tab. VI. fg 6, 2, head and part of the 
pronotum.) 
Oblong-ovate, piceous, the anterior angles of the pronotum, and the base of each of the connexival segments 
rather broadly, ochraceous, the posterior half or more of these segments obscure ferruginous within and 
blackish externally; the membrane smoky-black, with two obscure luteous marks at the base; the tibiz 
ferrugineo-testaceous at the base. Head subquadrate, granulate ; the post-ocular portions rather broad, 
with a short acute tooth at the outer angle, not extending outwards so far as the eyes; the apical process 
stout, subconical, moderately long, unemarginate at the tip; the spiniform antenniferous processes rather 
short, subparallel ; antennse with joint 1 stout, extending to about two-thirds beyond the apical process 
of: the head, 2 slightly shorter, 3 twice as long as 4, 4 short, piriform, not longer than 2, pilose at the 
tip. Pronotum broad, transverse, subtruncate at the base and apex, granulate, deeply sinuate at the 
sides before the middle, and narrowed in front; the anterior portion short and depressed, explanate at the 
sides anteriorly, with prominent rounded anterior angles, the disc with two flattened callosities and a median 
groove; the posterior portion parallel behind, rounded at the sides in front. Scutellum transversely 
wrinkled and with a median carina. Corium parallel at the base and of the same width as the pronotum, 
extending toa little beyond the first segment, the nervures granulate. Abdomen somewhat rounded at the 
sides, the sixth segment truncate behind, with the outer apical angles rather prominent; the genital lobes 
broad in the female, narrow in the male ; the spiracles small, the apical ones only visible from above. 
Length 47-63, breadth 2-22 millim. (¢ 2.)

Two males and one female. Allied to P. armatus, but with the head less transverse, 
the post-ocular spines short, the antenniferous processes shorter, the third joint of the 
antenne much more elongate, the anterior angles of the pronotum rounded, &c.
