This species is unknown to me. It is described (apparently from a single male 
example) as black, with the prothorax yellow; the head triangular, with the hind 
angles rounded, coarsely rugose, with a well-marked median groove; the antenne: 
black, long and filiform, with the second joint scarcely smaller than the others; the 
thorax campanuliform, moderately elongate, with a median groove, the surface punc- 
tured ; the elytra granulose ; the legs and underside (the thorax excepted) black; the 
hind tibial spurs broad, subequal. According to Dugés’ figure (12a), the head is 
triangular, much widened behind. 
6. Zonitis sanguinicollis. (Tab. XVIL figs. 20, 21.) 
Moderately elongate, depressed, finely pubescent, opaque; the head varying in colour from black or piceous 
_ . with the posterior portion more or less testaceous to entirely (the eyes, labrum, and mandibles excepted) 
flavous, the neck always flavous; the prothorax pale sanguineous; the scutellum varying in colour from 
black to pale sanguineous; the elytra black ; beneath (the head and prothorax excepted) black, the 
abdomen usually with the apex or the sides and apex—in some specimens almost entirely—pale san- 
guineous (sometimes black, with the fifth segment testaceous), the anterior portion of the breast some- 
times flavous; legs piceous or black, in some examples with the tarsi brownish or the anterior cox 
.  flavous. Head long and narrow, in some specimens very narrow, subparallel, with the hind angles 
rounded, irregularly, confluently, somewhat coarsely punctured, with an irregular smooth median space ; 
the labrum transverse; the mandibles long, curved, pointed; the palpi piceous or black, the last joint of 
the maxillary pair moderately long, cylindrical, truncate at the tip; antenne long and subfiliform, joints 
2 and 8 nearly equal, 4 a little longer than 3, 5-10 decreasing slightly in length, 11 longer than 10, 
subacuminate ; prothorax as long as or longer than broad, considerably narrowed in front, constricted at 
* the sides before the middle; campanulate, at the base very much wider than the head, deeply depressed 
on either side of the middle anteriorly, and with a smooth median line or groove, the surface closely and 
rather coarsely, in some specimens rugosely, punctured; scutellum densely and finely punctured; elytra 
broad, flattened, widening a little behind, at the base about twice as wide as the prothorax, conjointly 
rounded at the apex, the surface finely and densely granulate throughout; beneath densely and finely 
punctured ; hind tibial spurs rather slender, subequal; the fifth ventral segment unimpressed and broadly 
and semicircularly emarginate, and the sixth segment cleft down the centre, in the male. 
Var. The elytra yellowish-brown, with indications of three faint lines on the disc; the head (except i in front) 
sordid yellow ; the femora and front coxe testaceous ; the second joint: of the antennz: much shorter than 
- the third.
