Descriptions of New Scolytidse, 197 



certain resemblance to the species of Eutovins or Rliipid^ 

 andrus J the main structural characters agree well with 

 those of S. mikado, Blandf. I have received two 

 specimens from Mr. 0. E. Janson. 



Hylesinus wallacei, sp. n. 



Mas. Oblongo-ovalis, nigro-piceus, opacus ; fronte impressa ; 

 protliorace grosse f oveolato-punctato, apice et angulis anticis tuber- 

 culatis ; elytris crenato-striatis, interstitiis uniseriatim, ad basin 

 modo subirregulariter tuberculatis, et quam minutissime setosis. 

 Long. 4' 2 mm. 



Male. Oblong-oval. Head black, opaque, front and rostrum 

 widely impressed, subnitid, punctured and with a few minute 

 appressed hairs ; mouth reddish ; antennje brown-testaceous, the 

 club elongate. Prothorax moderately transverse, widest about the 

 base, the hind-angles rounded, the sides gently and regularly 

 incurved to th-i apex ; surface regularly and not strongly convex, 

 piceous-black, opaque, subglabrous, with large deep foveolate 

 punctures, close and in parts confluent ; median impunctate line 

 finely elevated behind, anterior margin with a row of tubercles, 

 larger on the apical angles, the sides submuricate. Scutellum 

 convex, transverse. Elytra twice as long as the prothorax, wider 

 at the base, their basal margins crenate and elevated but not 

 strongly rounded, the sides curved throughout, obliquely behind 

 the middle ; the apex not conjointly rounded ; surface piceous, 

 with strong crenately punctured striae ; interstices convex, unise- 

 riately tuberculate, the tubercles stronger, closer and transverse at 

 the base, smaller and rounder on the declivity, apex of the 2nd 

 interstice a little depressed ; elytral pubescence subsquamous, very 

 short and difficult to observe. 



Hah. Mysol (Wallace). 



Hylesinus despedus, Walk. 



I must refer to this Ceylonese species, with which I 

 have previously identified H. scohipennis, Chap., four 

 examples taken by Wallace, in Sarawak, Celebes, 

 Batchian, and Dorey in New Guinea, respectively. 

 The specimens show some differences, both in the depth 

 of the thoracic punctuation and the shape of the pro- 

 thorax, which, in all, except the Batchian example, is 

 somewhat trapezoidal, with a rather distinct muricate
