Cydostethus 62 obliquesignatus sp. nov. Plate 3, fig. 6. 
Ellipticus, niger, supra fuliginoso-, secundum suturam, ut 
spatiis raro, forimneo-, lineis tribus thoracalibus, elytris fascia 
obliqua utrinque postmediana, a stria secunda usque ad marginem 
lateralem, hie dilatata, extensa lituraque, oblonga, apicali, ut 
corpore subter, pallide ochraceo-squamosis ; rostro rufescenti, 
fortiter crebreque punctato, dorso in medio vitta levi ; prothorace 
minute remoteque granuloso, lateribus in dimidia parte basali 
fere parallelis, dein rotundato-convergentibus, in quinta parte 
apicali fortiter attenuatis; elytris sutura spatiisque alternatis, 
convexioribus, latioribus ac crebrius granulosis; femoribus anti- 
cis reliquis longioribus, dente majore armatis. 
Long. 5.7 ad 7.6 mm., lat. 2.4 ad 3.2.

Cydostethus lineolatus Pascoe 83 also has three ochraceous 
vittse on the prothorax; the remaining whitish pattern is said 
to be variable. The sculptural characters presented by the 
Philippine species were not mentioned for lineolatus. 
Rostrum coarsely and densely punctate, except a broad, short, 
smooth, dorsal stripe in the middle; antenna dark red, second 
joint of funicle hardly longer than first, the following gradually 
decreasing in size, fifth as long as thick and spheric like the 
remaining ones, the last transverse, club more than four times 
longer than thick; prothorax very minutely, scatteredly granu- 
late ; elytra hardly punctate in the stria, the suture and alternate 
intervals broader, more convex, and densely granulate; sides of 
metasternum and its episterna remotely punctate ; anterior tibia 
brownish, compressed in basal half. 
Pascoe has placed the genus Cydostethus near Cyamobolus 
and Euthyrhinus ; but because of the absence of ocular lobes one 
could be misled into placing it near Moemactes, following Lacor- 
daire’s key. 64 Supplementary to Pascoe’s diagnosis may be men- 
tioned the fact that in Cydostethus the eyes are very finely gran- 
ulate and separated in front by nearly half the breadth of the 
tibise. The scape does not reach the eye, the two basal joints 
of funicle are elongate, the femora beneath are without a fur- 
row fitted to receive the tibiae. The base of elytra is lobately 
produced, the end of rostral canal is excavated as in Gasterocerus 
and dissimilar in the scaled excavation shown by Euthyrhinus.
