I tliongbt at first that the peculiar structure of the jirouotum was due to 

 malformation : but as the thorax is symmetrical and the insect deviates from the 

 other Trayoci^phala also in possessing a comparativel\" very narrow mesosterual 

 process, 1 believe the structure of the pronotum to be normal for this species, 

 though abnormal for a Trai/ocjihala. 



The only other sj)ecies without marldngs on head audjjrothorax is T.ciirhonaria 

 (1892) Lameere. 



T4. Tragocephala suturalis spec nov. 



(J. Differs from all the sjiecies of Tragoccjihala in the elytra being ornamented 

 with a sntural vitta. A large patch on frons not reaching anterior edge, rounded 

 above, a spot behind eye, sides of prothorax, an elongate, mesial, basal, jjrouotal 

 spot ; on elytra : an elongate marginal spot below shoulder, a small median lateral 

 spot, a subapical rounded dot, a sntural vitta including scutellum, narrowing from 

 base to middle, jnst reaching an oblong jiostmedian sntural jiatch, of which the two 

 halves are sejjarated by the black suture, yellow : breast and sides of abdomen pale 

 yellow, anterior part of frons, cheek, and legs with a thin yellowish grey pubescence, 

 femora jiartly pale yellow. 



Frous finely jmnctured. Lower lobe of eye higher than broad, cheek less wide 

 at narrowest point than is the scape of the antenna at the base. Antenna reaching 

 beyond end of elytra. Prothorax rather short, coarsely rugate-punctate above, 

 basal lobe sinuate. 



Length, 20 mm. ; breadth, 7 mm.

Poimenesperus (1875) Thorns., Arcli. Ent. i. p. 35 (type : cohtptiiosas). 



To this genus belong Ni/ctopais tf/omsoni (1809) Pascoe, and Plmjnetal 

 velutina (1858) White. 



75. Poimenesperus callimus spec. nov. 

 ?. Similar to P. laetus. A thin mesial line on frons and a small ill-defined 

 spot anteriorly on cheek yellowish grey. Antenna entirely black. Markings of ujjper- 

 side of thorax and elytra vinaceons cinnamon, namely : sides of thorax including 

 spine, excejiting a black spot occupying the underside and (above) the tip of the 

 spine, the vinaceous cinnamon area widest at base and apex ; but the black area 

 remaining both at base and apex at least half as wide as the thorax is there broad : 

 a transverse basal band on elytra, abbreviated at shoulder, a marginal spot beneath 

 shoulder, an entire, straight liand before middle connected with the basal one at 

 suture, an apical patch, almost longitudinal, extending obliquely from outer margin 

 to sutural angle, halfmoon-shaped, convex discally. Sides of breast a little paler 

 than bands of elytra, middle of breast less densely (and more greyish) pubescent ; a 

 black lateral spot on metasternal sternite. Abdomen yellowish grey, a series of 

 large rounded lateral sjiots black, these confluont basally with a submedian spot on 

 segments 3 and 4, fifth segment brownish black, with a yellowish grey triangular 

 side-spot and a thin grey mesial line. Mid- and hindlegs irregularly and broadly 

 annulated or spotted with black and yellowish grey. Mesosternal process very 

 strongly projecting ventrad, compressed, conical.
