MORDELLA. 301 
brownish, the ventral segments (except the apices of 1-3 laterally) golden-pubescent ; pygidium very short 
and stout, blunt at the tip, not twice the length of the hypopygium ; legs slender (the hind pair excepted), 
black, the knees of the anterior and middle pairs reddish, the tibial spurs testaceous, the penultimate joint 
of the four anterior tarsi filiform, the intermediate tibie and tarsi equal in length. 
Length to end of the elytra 52, to tip of the pygidium 63, millim.; breadth 23 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. Allied to M. xanthosticta and M. sticticoptera, but differing from both 
these species in having the antenne considerably longer, more gradually and less 
broadly dilated (joints 5-7 relatively much narrower), and with the joints 8-10 only 
black, the eleventh being yellow; it is also larger and more elongate, and the golden 
pubescence on the elytra is differently arranged, the pubescence forming two fascie near 
the apex and two patches on the disc, between which are numerous small spots, these © 
spots arranged in a line on either side of the suture. 
53. Mordella panamensis. (Tab. XIII. fig. 14.) 
Rather short, brownish-piceous ; the head, prothorax, and scutellum clothed with yellowish-cinereous pubes- 
cence, the prothorax with a broad brownish-black-pubescent median vitta and an oblique stripe on either 
side of it (these markings not reaching the base or apex); the elytra with some irregular transverse 
markings at the base (enclosing an oblique spot on either side of the suture), some longitudinal markings 
at the side below these, a strongly angulated fascia at one-third from the apex, and an angulated 
fascia between this and the apex (both reaching the suture) yellowish-cinereous-pubescent, for the rest 
clothed with blackish pubescence (this forming a common large subquadrate patch before the middle and 
numerous spots); the pygidium cinereo-pubescent to the middle, blackish beyond. Palpi testaceous, the 
last joint of the maxillary pair elongate-ovate, slender ; antenne with joints 1-7 testaceous, 8-10 pitchy- 
brown, and 11 yellow, 3 and 4 very slender, elongate, subequal, 5-11 moderately widened, about equal in 
width, 5-10 decreasing in length, serrate, 6-8 about as broad as long, 9 and 10 transverse, 11 consider- 
ably longer than 10; elytra comparatively short ; beneath piceous, the venter paler, yellowish-cinereous- 
pubescent, the ventral segments with dark brown pubescence at the sides behind; pygidium short and 
stout, pointed at the tip, twice the length of the hypopygium ; legs slender (the hind pair excepted), in 
great part testaceous, the posterior femora and the apex of the posterior tibiee piceous, the posterior tibial 
spurs very elongate, the penultimate joint of the anterior and intermediate tarsi filiform. 
Length to end of the elytra 23, to tip of the pygidium 31, millim.; breadth 1j millim. ( 9.) 
Hab. Panama, David (Champion). 
One specimen. This little species is allied to M. tenuipes, from which it differs in 
its much shorter, serrate antenne (the apical joint being yellow,,not piceous), much 
shorter legs, and shorter elytra; the elytral pubescence is also differently arranged. 
The antenne are slender, though joints 5-10 are very distinctly serrate. 
54. Mordella T-album. (Tab. XIII. fig. 15.) 
Elongate, the head (except in the centre) and oral organs testaceous, the eyes, an indistinct spot on the middle 
of the vertex, the prothorax, elytra, and pygidium black; the head cinereo-pubescent ; the prothorax 
with a broad black median vitta and a large oblong oblique black spot on either side of it (these markings 
not reaching the base or apex), for the rest clothed with white pubescence; the scutellum white-pubes- 
cent; the elytra each with a long T-shaped white-pubescent mark on the middle of the disc just before 
the middle and a similarly-pubescent rather broad curved fascia a little before the apex, the latter coalescing
