NEW SPECIES OE LONGICORN COLEOPTE11A ALLIED TO 
COLO BO Til E A . 
BY II. W. BATES, F.L.S. 
The following descriptions refer to an interesting group of 
Lamiidtf, peculiar to Tropical America, which are closely allied to 
Astynomus , but differ in their narrow, laterally-compressed form of 
body, and the presence of a carina on each elytron, separating the 
vertical sides (epipleurae) from the dorsal surface. 
Syintchyzopus cancellatus. 
S. geometrico affmis et similis, sed differ t elytrorum signaturis. Purpureo- 
fascus, sericeo-nitens, capite thoraceque Jlavis, illo vittis duabus frontalibus, hoc fascia 
lata dorsali fuse is ; elytris marginibus (basi excepiis ) fasciisque duabus, august is, 
flavis, apice sinuato-truncatis angulo exteriori spinoso ; antennis piceo-fuscis, arti- 
culis 4 t0 et 6 to basi alb is. Long. 4% lin., £ . 
Differs from S. geometricus , of Nicaragua, chiefly in the fewer 
yellow lines of the elytra, which are so placed that each elytron may 
be said to have four large, square, silky-brown spots, separated from 
each other and the margins (except at the base) by narrow pale yellow 
lines. The thorax is much shorter than broad, with the sides 
moderately and regularly rounded in the middle. The lateral carina 
of the elytra is well marked near the base, but becomes obliterated 
before the middle. The ovipositor of the $ projects to the length of 
about one-twelfth of an inch beyond the elytra, and its dorsal plate is 
very acute at the tip, sharply grooved down the middle, and margined 
on the sides. 
Yungas of La Paz, Bolivia (Buckley). 
Synchyzopus ljetus. 
Purpureo-fuscus, sericeo-nitens , capite antice lineis tribus ( quorum mediava usque 
ad verticem continuata) thorace fascia angusta prope marginem anterior em, alter aque 
latiori ( medio interrupta) juxta marginem posteriorem, elytrisque utrinque maculis 
quatuor, pallide flavis ; antennis nigris, articulis 3 i0 , 4 t0 , et 6 (o basi albis ; corpore 
subtus medio griseo, pectore utrinque macula alba. Long. lin., $ . 
Very similar in form to S. geometricus and can cella t us, but dif- 
fering widely in the markings of the elytra. These consist, on each, 
of four pale yellow spots or short fascire, viz. : one rounded on the 
disc towards the base, a fascia near the middle, and a second fascia 
considerably beyond the middle (neither reaching the suture nor the 
margin), and a triangular spot at the apex (broadest on the suture). 
The ovipositor differs from that of S. cancellatus by wanting the 
central groove of the upper segment. In the specimen described it 
is red and shining. 
E. Moronas, Equador (Buckley).
