66 PHYTOPHAGA.—SUPPLEMENT. 
underside and legs are usually fulvous, but specimens occur with black underside. 
The other or more typical form is well represented in fig. 17, all the specimens 
obtained at Tapachula, as well as a single male at Escuintla (which certainly seems to 
better represent this sex of 7. sanguinipennis than the figure given of the variety), 
being thus coloured; this male has a narrower and entirely black thorax, agreeing in 
that respect with the females of 7. sanguinipennis. I have, however, received Guate- 
malan specimens from the Museum of Stuttgart which are intermediate between these 
two forms, these specimens having the thorax of the paler form and the elytra of the 
darker red variety, and the legs either black or fulvous. It seems to me that all these 
examples must be referred to one and the same species: they cannot be separated on 
such variable characters as the colour and markings of the upper surface and the 
sculpture of the thorax. 
6. Titubea brevilineata. (Tab. XXXVI. fig. 18.) 
Black; the basal joints of the antenne and the labrum fulvous ; thorax fulvous, impunctate; scutellum black ; 
elytra finely and semiregularly punctured, the suture, a marginal stripe at the middle, and an abbreviated 
stripe on the disc, black. 
6. Thorax with two small black spots; legs fulvous, the tarsi black. 
Length 3}-4 lines. 
3. Head finely rugose between the eyes, the vertex smooth and shining, black, with a small fulvous spot 
near each eye; anterior margin of the clypeus deeply concave-emarginate, fulvous, as well as the labrum 
and mandibles, the extreme apex of the latter black ; antennz not extending to the base of the thorax, 
the fifth and following joints strongly serrate, black, the lower four joints fulvous, the third joint monili- 
form and not longer than the second; thorax more than twice as broad as long, the sides strongly 
rounded, the posterior margin but slightly produced at the middle, the surface with some very minute 
punctures, fulvous, with a small obscure spot on each side; scutellum black, its apex raised, the base 
pubescent; elytra finely and closely punctured, testaceous, the sutural margin narrowly black, a narrow 
black stripe occupying the lateral margin from before to below the middle, and another narrow, slightly 
eurved, black line (parallel to the lateral stripe, and not extending to the base or apex) being placed at 
the middle of the disc; legs fulvous, the anterior tibie partly, and the tarsi entirely, black.

T. brevilineata seems closely allied to T. sphacelata, from which it differs in the 
narrow longitudinal discoidal stripe of the elytra, this being constant in the four 
specimens before me. In the female insect the legs are sometimes fulvous, sometimes 
black ; the thorax is, as usual, less transverse and more shining than in the male. 
7. Titubea hogei. (Tab. XXXVI. fig. 16.) 
3. Pale fulvous ; elytra opaque, pale testaceous, finely punctured ; anterior legs elongate, the tibie curved ; 
sides of the breast darker. 
2. Underside black ; elytra more strongly punctured. 
Length 3-34 lines. ‘ 
¢. Head fulvous, the vertex smooth, the lower portion finely strigose, the epistome separated from the face 
by a distinct triangular groove; the anterior margin of the clypeus deeply concave-emarginate in the 
middle and on each side; the apex of the mandibles black ; antennz black, the lower four joints fulvous, 
the third joint moniliform, the fifth and following joints strongly transversely serrate; thorax more than 
twice as broad as long, the sides strongly rounded, the surface with a few minute punctures and some
