NEW SPECIES OF A CAN TR ODE RES ( COLEOPTERA , LONGICORNIA, 
FAMILY LAMIA DAS). 
BY H. W. BATES, E.L.S. 
The genus Accinthoderes is interesting from its peculiar geo- 
graphical distribution. Having its head quarters in Tropical America, 
a few outlying species are found in Western Africa, and in the tem- 
perate zones of North America, Asia, and Europe. The chief European 
representative is the well-known A. varius, which seems to stand in the 
relation of a “ synthetic ” type to the divergent and wonderfully- varied 
specific forms, undoubtedly congeneric, which abound in South America. 
Acantiioderes vetustus. 
Elongato-oblongus, sub-depressus, rufescenti-fuscus, elytris litura circumflex a 
pone medium , guttisque numerosis, atro-fuscis ; lineis obliquis ( quorum duabus 
utrinque angulariter dispositis prope basin , alteraque angulari prope apicemj 
guttisque apud suturam et latera, cinereis ; thorace tuberculis dorsalibus ( duobus ) 
lateralibusque validis, his cinereo-cinctis : elytris cristis basalibus serratis, carina 
dorsali nulla; dorso sparsim punctatis, apice sinuatim transverse truncatis, angulo 
suturali prominulo, exteriori spiniformi : antennis corpore multo longioribus, articulis 
3 — 6, cinereo-biannulatis, 7 — 11, basi cinereis: tarsis rufescenti-cinereis, posticis 
angustis, articulo primo elongato. Long . 6 — 8| lin., ^ . 
South Brazil and Ecuador (Macas, Buckley). Belongs to a group 
of species of similar elongated form and variegated markings, which 
have slender hind tarsi and rather narrow mesosternum. 
Acantitoderes longitarsis. 
Valde elongatus, convexus, rufescenti-fuscus, nigro-punctatus, lituraque circum- 
flexa elytrorum pone medium nigra : thorace tuberibus validis: elytris medio longi- 
tudinaliter costatis, tuberculis parvis acutis asperatis, apice truncatis et utrinque 
cequaliter bidentatis : tarsis fulvis, posticis articulo primo gracili, quam 2 et 3 con- 
junct is multo longiori. Long. 12 1 lin., £ . 
Ecuador (from the Saundersian collection). In this species, the 
length and slenderness of the first joint of the hind tarsi reaches its 
maximum. The elytra have no trace of the cinereous lines which dis- 
tinguish A. vetustus ; the antennae are ringed with cinereous or fulvous 
in a similar manner in all the allied species. 
Acantiioderes sat anas. 
A. Sweden proxime afpnis at major, prcecipue robustior. Latissimus, niger, 
opacus ; capite (prope labrum ) maculis duabus minutis, thoraceque lateralibus 
duabus fere obsoletis, flavis : elytris apice rotundatis, maculis flavis utrinque 
duabus (altera suturali altera later ali) , guttis duabus ad basin, alterisque (duabus vel 
tribus) sub-obsoletis ad apicem : pedibus validissimis nigris, tarsis latis, articulis 
3 <?£ 4 fulvis : pectore immaculato. Long. 8 lin., $ . 
Chanehamayo, Peru (Thainm).
