EROTYLIDAE. 135 



Hah. N. E. Sumatra: Tandjong Morawa, Serdang (Dr. 

 B. Hagen). — One specimen. 



The head ia this species is opaque , excepting at the 

 base, where motion takes place, here it is shining and 

 with distinct punctures. The ocular sulcus , which is distinct 

 in E. verticalis and in E. Hageni, is quite obsolete. The 

 three spots on the head are united. The antennae in both 

 this species and E. Hageni seem exactly as in E. verticalis. 

 The thorax is more quadrate, and has the front angles 

 more produced than in the preceeding species , and its opaque 

 surface can hardly be called punctate , but has a carina 

 in the middle , terminating in a small impression in the 

 middle of the base. The sulcate elytra are unlike those of 

 any described species, being less opaque than those of E. 

 opaca Crotch , but with costate interstices , the alternate 

 costse more distinctly raised. 



The denticulate markings recall those of some Triplatomce. 

 The specimen is no doubt a female , the prosternum is 

 not raised , but is impressed at the end of the intercoxal 

 process. It is not at all pubescent, but is opaque. 



Encaustes ceramensis, n. sp. 



Oblonga , postice paululum angustata , nigerrima , nitida ; 

 elytris lunula humerum subcingente, maculaque subapicali 

 arcuata sanguineis , tenuiter punctato-striatis. — Long. 

 16—20 millim. 



Hab. Ceram: Wahaai (Moens). — One specimen. 



This species and some _ allied ones are jet-black , with 

 the exception of a blood-red mark near the shoulders, 

 and an apical spot. In E. ceramensis the head is punctu- 

 red very finely , the epistome is only marked by the front 

 being depressed; the ocular stria margins the eye from 

 the antenna to the back where it leaves it, diverging and 

 terminating on a level with the hind-margin of the eye. 



The thorax is covered with minute points, the basal 

 sulci indicated by a group of larger points. The front an-
