250 HEXAGONTA LUCASSENII. 



the hinder angles, which are slightly projecting and acute, 

 the base nearly straight; the disc with a broad deep li- 

 near impression along the middle, abbreviated anteriorly 

 and posteriorly, the lateral margins narrowly grooved, on 

 each side at the base an oblique strong impression , coar- 

 sely punctured all over. Elytra with the shoulders obsolete 

 and broadly rounded , the sides straight and parallel , con- 

 jointly and gradually rounded at the apex with a slight 

 emargination before the top; rather strongly punctate- 

 striate , the intervals plain and impunctate , except the 

 third which is provided with three shallow large punctu- 

 res, one near the base, one below the middle and an other 

 close to the top , and the fifth interstice which shows a 

 single puncture at some distance from the apex. Under- 

 neath rather smooth, the head finely plicated in a trans- 

 verse direction , the prosternum densely punctured. 



This species has some resemblance with the African H. 

 praeusta Chaud. At the request of Mr. Ritsema, I have 

 dedicated this species to Mr. Lucassen.

The Leyden Museum possessed already a specimen cap- 

 tured by Dr. de Gavere near Batavia, when recently two 

 specimens were sent over by Mr. Lucassen from Boemiajoe 

 (Tegal : Java) at the feet of Mt. Slamat at a height of about 

 1000 feet. They correspond so well with Schmidt-Göbel's 

 description and figure (Faun. Coleopt. Birman. p. 51, pi. 2 

 fig. 2 1 )) that, notwithstanding the different localities, I 

 dare not treat our Javan insect as distinct. The only character 

 of which no mention is made in the careful description , is 

 the presence of rows of very large and closely set trans- 

 verse piceous dots on the elytra. 



1) According to the Munich Catalogue, H. apicalis Schm. Göb. should be fi- 

 gured on pi. 2 fig. 1, which is quite erroneous, that species not being fi- 

 gured at all.
