FORMOSAN ANTHBIBTBAE COLLECTED BY H. SAUTER. 



By Dr. K. JORDAN. 



'T^HE only species of Anthribidae recorded from Formosa is Sintor fasciatus 

 -L Jord. (1903). The collection made by Herr H. Sauter on that island and 

 submitted to me by the Dentsehes Entomologisches Mnseum in Berlin contains no 

 less than thirty-one species. Two of them are represented only by an imperfect 

 specimen each, not good enough for description or identification and therefore not 

 mentioned in the following list. 



As must be expected, some of the species are either identical with those known 

 from Japan on the one hand and Tonkin on the other, or are modifications of them. 

 The Anthribid fauna of China is hardly at all touched, only a very few forms being 

 known from that country. Considering the number of species found in Japan, the 

 present collection from Formosa no doubt represents only a fraction of the species 

 which actually inhabit that island, but it contributes nevertheless so much to our 

 knowledge of the distribution of this family that a list of the captures deserves 

 publication. 



The types of the new forms are in the D. Ent. Mus. 



1. Acorynus anchis spec. nov. 



c??. Niger, rostro et pagina inferiore corporis dense luteo tomentosis ; 

 protborace fortiter pnnctato, lougitudine latiore, supra vitta meiliana angusta plus 

 minusve interrnpta, ntrinque gutta discali atque tribus maculis lateralibus luteis 

 signato ; elytris area magna basali fere ad suturae medium extensa antice nigro 

 maculata ut area apicali magna lutea, macula transversa raediana dorsali in utroi^ue 

 elytro griseo-lutea notata ; pedibns nigro-brunneis, tibiis luteo biannulatis, inter- 

 mediis in i ad apicem mucronatis, tarsornm articulo 1° apice luteo. 



Long. (cap. excl.) 5"5 — 7"5 mm. 



1 S and 5 ? ? from Koserapo, Fuhosho and Taihoriusho. 



Allied to A. tonkinanm Jord. (1904), but much less robust. Rostrum only 

 ^ to i longer than broad, rather flat, with five prominent carinas. Frons narrowing 

 anteriorly, in S half the width of and in ? a little wider than the interspace between 

 two dorsal carinae of the rostrum. Occiput with large brownish black triangular 

 patch. Antennae rufescent at the joints, segments 8 and 10 very short. Carina of 

 thorax laterally extending forward in an even curve, i caching to the middle of the 

 side, straight dorsally ; the pnncturation of the prothorax above and beneath rather 

 coarse ; there is a transverse depression in front of the centre, but no channel ; the 

 clay median stripe is interrupted before the middle and widened at and behind the 

 carina. The large basal Inteous area of the elytra is truncate at the suture and 

 consists of a number of confluent spots, the black interspaces between the spots 

 being more or less large at and near the base ; behind shonlder-angle a spot rather 

 paler than the dorsal part of the clay area ; the solitary median spot usually expands 

 between interspaces 'Z and and is often broken up ; the clay apical area hears on 

 each elytrum a ramificating black spot and is 'somewhat produced forward at the 

 suture. The clay pygidium has a diffuse black median stripe.
