the Staph jlinidffi of Japan. 881 



black, broadly, especially at the posterior angles, reddish or 

 yellowish at the sides, finely and not closely punctate, and 

 finely strigulose. Punctuation of elytra fine, though a good 

 deal coarser than that of the thorax ; their colour is dark, but 

 a large vague red mark exists at the shoulder. The punctua- 

 tion of the hind body is close and fine, and the hind margins 

 of the segments are yellowish. 



In the male the last dorsal plate forms in the middle an 

 angular projection, the apex of the projection being divided 

 by an angular notch that is evidently longer than broad, and 

 each outer angle of the plate projects as a short but quite 

 distinct tooth ; the corresponding ventral plate terminates in 

 two slender, parallel, linear, widely separated laciniaj, and 

 each outer angle forms a rather long tooth ; the hinder part 

 of the preceding plate is deeply and rather broadly circularly 

 emarginate, and the posterior part of the emargination is set 

 with asperities ; at each side of the emargination behind the 

 surface is elevated in a plicate manner. 



This species resembles T. hipustulatusy but is more slender 

 and has longer and thinner antennje and very distinct male 

 characters ; the slender, parallel, distant laciniaj of the last 

 ventral plate are remarkable, as is also the fact that the sides 

 of the emargination of the preceding segment are plicate in 

 such a manner as to form the rudiments of lacinia3. The 

 female is unknowni. 



Three specimens have been found ; Nikko, 25th August, 

 1881, and Sapporo. 



Tachinus luridus, n. sp. 



Niger, nitidus ; elytris ex parte majore luride rufescentibus, anten- 

 narnm basi piceo, pedibus rufis ; thorace elytrisquo subtilius 

 punctatis, dense strigulosis ; abdomine sat crebre vix subtiliter 

 punctato, tenuiter sed perspicue pubescente. 



Long. 6 millim. 



Antennae black, with the basal joints rather paler, tenth 

 joint about as long as broad. Thorax entirely black, only 

 very finely and sparingly punctate, but very evidently stri- 

 gose. Elytra more, closely and coarsely punctate, but still 

 only finely ; they are of a rufescent colour, becoming darker 

 behind and about the suture. 



In the male the middle part of the last dorsal plate is only 

 a little prolonged and forms in the middle two short teeth, 

 which project only slightly further back than do the short, 

 broad, lateral teeth. The last ventral plate is divided in the 

 middle by a deep, narrowly oval excision ; the sides of the
