MORDELLA. 287 
reddish-brown elytra and sides of the thorax, the sparser pubescence, &c. The elytra 
have a distinct broad oblique stripe of paler pubescence on the posterior half and a 
faint oblique line of paler pubescence running from the shoulders downwards. The 
pygidium is very long and slender, pointed at the tip. The intermediate tibie are 
sinuously curved inwards. The punctuation of the upper surface is very fine and 
shallow. 
30. Mordella flavolineata, (Tab. XII. fig. 17.) 
Moderately elongate, rather broad, black, the humeri obscure castaneous, the pygidium reddish; the head with 
a line of bright golden pubescence on either side (not extending behind the eyes), for the rest brownish- 
black-pubescent ; the prothorax with an oblique stripe of bright golden pubescence on either side of the 
middle of the disc extending from the apex nearly to the base, and a little golden pubescence at the base 
near the hind angles, for the rest blackish-pubescent ; the scutellum blackish-pubescent ; the elytra each 
with a narrow interrupted slightly oblique fascia towards the sides just below the base, a narrow 
transverse fascia some little distance beyond the middle (not reaching the suture), and the apex narrowly 
bright golden-pubescent, for the rest clothed with blackish pubescence; the pygidium golden-pubescent to 
about the middle, darker beyond. Head obsoletely canaliculate ; palpi and oral organs testaceous, the 
last joint of the maxillary palpi elongate-ovate, narrow ; antenne entirely flavo-testaceous, very long, 
joints 3 and 4 very slender, elongate, subequal, 5-11 moderately dilated, equal in width, all very much 
longer than broad, 5-10 slightly decreasing in length, serrate, 11 elongate-ovate, scarcely longer than 10 ; 
elytra moderately long; beneath black, the last two ventral segments reddish, the latter and a small spot 
on the sides of the first ventral segment in front bright golden-pubescent, for the rest clothed with 
brownish-black pubescence ; pygidium rather slender, comparatively short, twice the length of the hypo- 
pygium; legs slender (the hind pair excepted), the two anterior pairs and the posterior tibial spurs 
testaceous, the hind pair piceous but with the tarsi in great part reddish, the third and fourth joints of the 
anterior and middle tarsi very feebly widened. 
Var. The lines of pubescence on the head and prothorax white, those on the latter extending to the base, the 
sides of the prothorax also with some whitish pubescence ; the pubescence on the scutellum and at the 
base of the first ventral segment white ; the postmedian fascia of the elytra placed nearer the apex, a 
little curved, and almost extending to the suture, the golden pubescence at the apex quite obsolete. 
Length to end of the elytra 43-43, to tip of the pygidium 5-53, millim.; breadth 2 millim. 
Hab. Mexico (Sallé); Guatemana, Senahu (Champion). 
One example only from each locality, probably male and female; the Guatemalan 
one is taken as the type. In the variety the lines of pubescence on the head and thorax 
are white instead of golden-yellow, the markings on the elytra being of this colour in 
both forms. The species is not at all closely allied to any of the other Central-American 
Mordelle. In the form of the antenne it approaches J. pretosa, but it has shorter 
legs and a more slender pygidium ; the antennz are entirely flavo-testaceous, long, and 
have their third and fourth joints very slender; the penultimate joints of the anterior 
and middle tarsi are very slightly dilated, these joints being narrow and filiform in 
M. pretiosa. The typical example is figured. 
31. Mordella flavofasciata. (Tab. XII. fig. 18.) 
Moderately elongate, narrow, black, the mouth-parts (the tips of the mandibles excepted) testaceous ; the head, 
prothorax, and pygidium sparsely clothed with yellowish-cinereous pubescence ; the elytra with a broad 
fulvous-yellow transverse fascia a little below the base and a similarly coloured fascia beyond the middle
