ACYLOPHORUS.—MIMOSTICUS. 327 
piceous, very shining. Elytra rather darker, but still not quite black. Hind body with 
each segment strongly purpurescent behind; on the penultimate segment the colour 
behind becomes reddish, and the terminal segment is still more dilute behind. The 
legs are red, the anterior brighter than the posterior ; the genz behind the eyes are 
densely and finely punctate, but the under surface of the head is very little punctate. 
Only one individual is known. 
8. Acylophorus palpalis. (Tab. VIII. fig. 1.) 
Minus convexus, nigricans; oris partibus pedibusque testaceis, tibiis fuscis; elytris cum scutello dense punc- 
tatis; abdomine subtiliter punctato, dense pubescente, ante apicem rufo-cingulato; palporum articulo 
ultimo incrassato, femoribus posterioribus hirsutis. 
Long. 73 millim. 
Hab. GUATEMALA, San Gerdnimo (Champion). 
This insect will readily be recognized by the greater than usual development of the last 
joint of the maxillary palpus; the minute acumen with which it is provided is moreover 
placed on one side of the apex instead of in the middle; the hind femora are unusually 
densely pubescent beneath, and on the upper surface the pubescence is distinctly visible 
at their margins. The hind margin of the sixth segment of the hind body is rufescent, 
and the terminal segment is broadly red at the base. The gene behind the eyes are 
extremely finely punctate and pubescent, while the under surface of the head is but 
slightly so. 
A pair of this species has been found. 
9. Acylophorus planatus. 
Minus convexus, nigricans; capite thoraceque nitidissimis; elytris haud longioribus quam thorax, fusco-piceis, 
cumque scutello dense punctatis, haud nitidis; abdomine versicolore, dense punctato denseque pubescente 
et setuloso, segmentis sexto et septimo singulatim ad apicem rufis; pedibus testaceis. 
Long. 73 millim. 
Hab. Nicaragua, Chontales (Janson). 
Head rather large ; antennz rather long and stout ; the gene behind the eyes densely 
and finely punctate; under surface of head very evidently pubescent and punctate. 
Hind body with a strongly opalescent or iridescent tint, and with the clothing of hairs 
and sete greatly developed; the hind margin of each of the two terminal segments 
conspicuously yellowish red, and the extreme base of the terminal segment also of 
this colour. The parts of the mouth are yellow. 
Of this distinct species only one example has been met with. 
MIMOSTICUS. 
Genus inter Quedium et Acylophorum quasi intermedium, ab hoc ‘antennis haud geniculatis, ab illo antennis 
subfractis articulo basali longiore, prothoraceque absque membrano stigmatico, distinctum. 
This genus is closely allied to the Australian Quediopsis, Fauvel, from which it differs
