256 Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 



with the interstices apparently [for the sculpture is somewhat 

 obscure] subcostate and crenulated ; and with longitudinal rows 

 of short distant setae down each. Limbs a little paler than the 

 rest of the surface. 



The discovery of this curious beetle is due to the indefatigable 

 researches of Mr. Bewick e, who captured a single specimen of 

 it in his garden at the Palmeira, above Funchal, amongst some 

 dried stems of the Euphorbia piscatoria which he had brought 

 several months before from Porto Novo, on the eastern coast. 

 Whether, therefore, it was transported to Funchal, along with 

 the numerous other Coleoptera which inhabit the stems of the 

 Euphorbias, or whether its appearance amongst them was merely 

 accidental, it is impossible at present to decide. Be this, how- 

 ever, as it may, there is, at any rate, no reason for suspecting 

 that the insect is otherwise than indigenous. 



Genus LYCTUS. 



Fabricius, Ent. Syst. i. ii. 502 (1792). 

 Lyctus Leacocianus, n. sp. 



L. cylindricus, parce pubescens, niger ; capite prothoraceque crebre et 

 profunde punctatis, hoc subquadrato, angulis anticis haud pro- 

 ductis sed posticis paulo acuminatis ; elytris leviter sub-biseriatim 

 punctatis (punctis elongatis angustis), sutura interstitiisque alternis 

 obsoletissime elevatis ; antennis (robustis) pedibusque piceis.

L. linear and cylindrical, but rather broader than the L. brun- 

 neus, also of a darker hue (being nearly black), and somewhat 

 less densely clothed with decumbent fulvous pubescence. Head 

 and prothorax a little more coarsely punctured : the latter more 

 strictly quadrate the anterior angles being rounded-off, and 

 not downwardly produced as in that species ; but with the ex- 

 treme hinder angles more acute, or prominent; the sides not 

 perceptibly crenulated, even beneath the microscope ; the disk 

 rather more even and convex, but nevertheless with the longi- 

 tudinal depression more lengthened, or converted into a wide 

 dorsal channel. Elytra more closely and distinctly punctulated 

 than in the L. brunneus, the punctures being narrow and elon- 

 gated (like broken striae), with a tendency to be arranged in 

 double longitudinal rows, and both smaller and more dense (as 

 well as more irregular) towards the suture than towards the 

 margin ; the suture and alternate interstices obsoletely raised. 

 Limbs dark-piceous ; the antenna more robust than those of 

 the L. brunneus.
