Syxchyzopus polystigma. 



Niger, capite antice genis et lineis tribus frontalibus (quarum mediana usque ad 

 thoracis basin externa) elytrisque utrinque maculis novem, Jlavis : antennis articulis 

 4 to et 6 t0 basi albis : corpore subtus griseo, lateribus cinereo-albo maculatis. 



Long. 5 lin., $ {excl. ovipos.). 



Distinct from all other described species by the central yellow 

 vitta of the thorax, and the numerous pale markings of the elytra ; the 

 latter consisting, on each, of nine spots. These spots are : — one, the 

 largest, central on the suture and common to both elytra ; two, small, 

 on the epipleurse ; four, also small, scattered over the basal half of 

 the disc ; one, rather larger and more transverse, towards the apex ; 

 and one on the apical margin. The whitish spots on the sides of the 

 body beneath begin with two narrow belts on the flanks of the pro- 

 thorax, and are continued, one on each sternal plate and ventral 

 segment, to the apex. The thorax is rather more elongate than in 

 the preceding species, its broadest part being much nearer the base, 

 whence it tapers towards the apex. The elytra are considerably 

 narrowed from base to apex. The ovipositor projects one-eighth of 

 an inch beyond the elytra, and its dorsal segment is convex and un- 

 grooved.

Synchyzopus duplex. 



Fades Colobotliearum : elongato-angustus, nigro- vel purptireo-fusctts, sericeus, 

 fronte lineis tribus, vertice vitta latiori usque ad thoracis marginem posteriorem 

 extensa, elytrisque plaga macularia basali fasciisque flexuosis duabus versus apicem, 

 carneo-ochraceis : thorace sub-cylindrico medio paullulum dilatato ; elytris apice 

 truncatis extus spinosis ; antennis nigris vel piceis, articulis 4 t0 et 6 to basi cinereo- 

 albis : subtus medio griseo lateribus dense cinereo-vittatim tomentosis. 



Long. 4 — 5| lin., $ $ . 



In colour and markings much resembling the species of Colo- 

 bothea. but distinguished from that genus by the narrower thorax 

 (slightly rounded in the middle), and by the ovipositor of the female 

 being slender and projecting considerably beyond the tips of the 

 elytra ; both which characters are those of Synchyzopus. The upper 

 segment of the ovipositor ends in a sharp point, and is plane above. 

 The spotty, ochreous or pinky-ochreous patches of the elytra are spread 

 very irregularly over the base, but in the middle and towards the apex 

 they are condensed into transverse flexuous belts, and the apex has a 

 large transverse spot of the same colour.
