MORDELLA. 271 
coloured pubescent spots at the sides of the ventral segments and on the sides of 
the breast are equally variable :—in a, 6, 8, « they are more or less well marked, in 
y, ¢ 9 they are altogether obsolete, and in » they are very small or quite obliterated. 
The antenne in both sexes have their joints 5-10 broadly serrate, 7-10 being very 
/strongly transverse ; the head is very narrowly extended behind the eyes and distinctly 
canaliculate; the elytra are flattened on the disc, and have a long oblique humeral 
callus; the pygidium is very long and acuminate (in some specimens fully equalling 
half the length of the elytra), only a little shorter in the female, about twice the length 
of the hypopygium ; the penultimate joints of the anterior and middle tarsi are mode- 
rately widened; the anterior tibie are slightly curved in the male; the last joint of 
the maxillary palpi is triangular, not very stout. Var. 6 bears the name U/. terminalis, 
Chevr., in the Sallé collection. The insect varies in length from 74-104 millim. 
(pygidium excluded), the pygidium from 3-44 millim.

Like MZ. quadrisignata, Chevr., a very variable species, as regards the colour—ashy, 
golden, or fulvous—and pattern of the thoracic and elytral pubescent markings. ‘The 
insect is apparently much rarer than J. quadrisignata ; but the few examples received 
of the different forms clearly run one into the other, though none of them agree exactly 
in the elytral markings with the type. The following variations occur :— 
a. Head, two transverse lines on the thorax—one along the base, the other towards the anterior margin, 
the latter with a short line extending downwards on either side of the middle,—the scutellum, the 
commencement of the suture, two punctiform spots towards the middle, and two fascize—the first 
elbowed, the second widened in front, without reaching the suture,—cinereo-pubescent. 
Hab. Guiana, Cayenne !. 
3. Head, three transverse lines on the thorax—one along the base, rather broad, the others narrow, one 
towards and the other along the anterior margin,—the scutellum, an oblique stripe on the disc before 
the middle—very nearly coalescent with an oblong antemedian sutural patch (forming with this and the 
oblique mark on the opposite elytron a large V-shaped mark), and with a transverse ramus in front 
extending outwards,—an anteapical fascia (narrowing outwardly), and the suture from the base to the 
antemedian patch and from this to the anteapical fascia yellowish-cinereous, (Fig. 19.) 
Hab. Panama, San Feliz in Chiriqui (Champion). 
One example. 
y. Head in front and narrowly along the base, three transverse lines on the thorax—one at the base, rather 
proad, one a little distance before and another along the anterior margin, both narrow, the former with a 
short line on either side of the middle extending downwards,—the suture nearly to the middle, broadly 
so behind, a punctiform spot on the disc a little below the base, a faint transverse mark between this and 
the lateral margin, and a broad anteapical fascia, nearly reaching the suture and excised on its anterior 
edge, yellowish-cinereous; the scutellum black. (Fig. 20.) 
Hab. Nicaraeua, Chontales (Belt). 
One example.
