I30 FAUNA HAWAIIENSIS 



Pronotum narrowed in front but not collared ; mediolongitudinally carinate ; posteriorly 

 produced over anterior margin of scutellum ; twice to 2\ times as long as head, and 

 nearly four times as long as scutellum (macropterous) or 3^ times (brachypterous) ; 

 claval commissure 3 — 3^ times as long as scutellum. 



Macropterous : corium very long, one-half longer than abdomen, apically acuminate, 

 apical margin sinuate, costal margin narrowly reflexed ; corium with an apically 

 evanescent mediolongitudinal nervure. 



Brachypterous : like the former but altogether much shorter. 



Type Siilaniita /uiiali/o Kirk.

Plate IV. figs. 12 — 14. 



More or less shining, very variable in pattern. Head, pronotum, scutellum and 

 clavus black ; pronotum mediobasally and clavus medioapically, obscurely pallid. 

 Corium black, interior area and apicoexteriorly, pallid cinereo-testaceous. Beneath black, 

 except antennae and legs which are immaculate pallid testaceous ; third and fourth 

 and apex of second segments of antennae fumate. Rostrum pallid, apically fumate. 

 Membrane hyaline subfumate, nervures subfumate. Vertex very finely punctured except 

 submedianly on each side ; nearly three times as wide at base as one eye. Eyes 

 touching pronotum. Rostrum reaches base of intermediate coxae, short, thick ; fourth 

 segment flattened, dilated. Antennae a little shorter than body-length including elytra, 

 or a little longer than length to apex of abdomen ; second segment 2^ times as long 

 as first, about three (?) times as long as fourth'. Pronotum anteriorly sometimes not 

 impresso-punctate, but subrugose-punctured ; base of pronotum subtruncate (slightly 

 subangularly emarginate) ; posterior femora not reaching apex of abdomen ; coxae 

 practically contiguous.

 of third, and fourth (entirely) segments of antennae, scutellum, apical margin of corium, 

 and the ventral surface — black. Pronotum sometimes distinctly, though slightly, 

 constricted and transversely impressed.
