Long. 101 lin. 



Hob. — Philippine Islands. 



Front impressed with a deep groove, which ends on 

 the vertex in a transverse sulcation. Thorax at the base 

 not broader than long, sides narrowly margined, nearly 

 parallel from the base to just beyond the middle, thence 

 obliquely converging to the apex ; immediately in front 

 of the base is a small indistinct tooth ; upper surface 

 sub-opaque, its anterior third deflexed, impunctate, hinder 

 two-thirds transversely convex, impressed on either side 

 in front with a broad transverse depression, which ex- 

 tends laterally as far as the outer margin; on the 

 medial line is a faint longitudinal groove, terminated 

 anteriorly at the base of the deflexed portion by a small 

 shining tubercle ; hinder part of the thorax (with the ex- 

 ception of a broad longitudinal space on the middle) deeply 

 punctured. Elytra elongate, parallel, sides obliquely 

 converging near the apex, the latter conjointly subacu- 

 minate; each elytron emarginate at the sutural angle, 

 and armed with a short acute tooth. 



Genus EsTiGMENA, Hope.

Elongata, parallela, convexa, dorso depressa, fulvo- 

 flava, nitida ; oculis, antennis (basi excepta) , elytrorumque

Long. 4| lin. 



Hah. — Tondano; collected by Mr. Wallace. 



Antennae scarcely more than a third the length of the 

 body, basal joint flavous, the apical one obscure nigro- 

 fuscous. Thorax longer than broad, sides straight and 

 parallel, rounded at the extreme apex; upper surface 

 smooth and shining, deeply excavated on either side 

 close to the lateral border, impressed in front of the 

 basal margin with a large round fovea; the excavated 

 portions coarsely punctured. Elytra broader than the 

 thorax, sides parallel ; apex subacutely rounded ; upper 

 surface flattened along the suture, deeply punctate- 

 striate; stri^ sulcate, their interspaces costate.
