TITUBGA. 67 
irregular depressions, of which a more strongly marked one is placed near the anterior angles; scutellum 
fulvous; elytra narrower than the thorax, very pale testaceous, opaque, with indistinct rows of fine 
punctures, the interstices sparingly clothed with short fulvous hairs; below and the legs fulvous, the 
breast black; anterior legs much longer than the others, their tibie strongly curved at the apex, their 
tarsi piceous and with the first joint as long as the two following ones together. 
Hab. Mexico, Iguala in Guerrero (Hége). 
This species, of which only one male and three females were obtained, may be at 
once known from its allies by the absence of any dark markings above, the whole 
upper surface being pale fulvous. The females (in which, as usual, the thorax is less 
transversely-shaped) have the entire underside black and clothed with yellowish 
pubescence; and the elytra much more strongly punctured and the punctuation 
arranged near the suture in double rows. 
8. Titubea guatemalensis. 
Fulvous, the terminal joints of the antenne, the anterior tibie and tarsi, and the breast, black; elytra testa~ 
ceous, almost imperceptibly punctured, the interstices sparingly clothed with short black erect hairs. 
Length 33 lines. 
Hab. Guatemata, San Gerénimo (Champion). 
Only a single male specimen of this species, which I must separate from the pre- 
ceding, is before me. Like 7. hégei, the colour of the upper surface is pale fulvous, 
but the elytra are almost impunctate and their pubescence is black and only visible in 
certain lights; two very small obscure spots (which may be the remnants of a band) 
are visible below the middle of the latter; the anterior tibize are entirely black, and 
not so strongly curved as in the male of 7. hégei; and the general shape of the body 
is much broader and more robust. T. guatemalensis may, however, be only a local 
form of 7. héget. 
9. Titubeea villosa. (Tab. XXXVI. fig. 17.) 
Black, pubescent; the labrum fulvous, spotted with black; elytra fulvous, clothed with short, pubescence, a 
broad transverse band below the middle, extending upwards along the suture, black. 
Length 3-33 lines. 
Hab. Mexico, San Miguel, Etla (Sal/é). 
This species exactly resembles in colour 7’. mutabilis, and can only be separated from 
it by the short greyish pubescence which covers the entire upper surface. The head 
is either entirely black or has two fulvous spots at the sides; the three basal joints of 
the antenne are generally fulvous, but sometimes the first joint is black; the thorax is 
- entirely black in some specimens, or margined with flavous in others; and the broad 
elytral band varies as much in width and length as it does in 7. mutabilis. The single 
male specimen before me is larger and has, as usual, a more transversely-shaped thorax, 
and the four anterior femora fulvous below. In all examples the elytra are finely 
margined with black at the apex and at the posterior portion of the suture.
