Tachinus mgriceps, n. sp. 



Piceus, nitidus ; capite nigro ; antennis, palpis, thorace pedibusque 

 flavis ; thorace breviore, parce siibtihssime punctulato ; elytris 

 abdomineque crebrius minus subtiliter punctatis. 



Long. 4 milhm. 



Antennee rather long and slender, entirely yellow, third 

 joint much longer than second, tenth about as long as broad. 

 Head quite black, very shining, broad and short. Thorax 

 strongly transverse, shining yellow, broadly rounded at the 

 hind angles. Elytra and hind body shining, very distinctly, 

 not altogether finely, punctate. 



In the female the last dorsal plate is trifid, the middle lobe 

 being broad, parallel-sided, and terminated behind by a broad 

 short emargination, so that each angle of the lobe is slightly 

 acute ; this central lobe is separated by only a small notch 

 from the short broad lateral tooth, which projects just as far 

 back as the middle lobe. The last ventral is sexdentate, the 

 two middle teeth being broad and very short, the external 

 tooth longer i\nd slender. 



This distinct species is somewhat similar to T. coUans. 

 Only a single example has been found,

Tachinus impunctatus, n. sp. 



Nitidus, niger ; antennarum basi, palpis, thorace pedibusque tes- 

 taceis ; fere impunctatus ; abdomine nitidiore ; antennis gracil- 

 limis. 



Long. 7-8 millim. 



Antennge elongate, very slender, one or two of the basal 

 joints yellow, the others dark, tenth joint three times as long 

 as broad; palpi elongate. Head narrow, impunctate^ black. 

 Thorax quite shining, impunctate, yellow, the hind angles 

 much rounded. Elytra nearly black, pitchy at the hind mar- 

 gin, without punctuation, and only very obsoletely strigulose. 

 Hind body shining black, almost impunctate. Legs long and 

 slender. 



In the male the last dorsal plate terminates in four nearly 

 similar and equidistant teeth, like those of a saw; the last 

 ventral plate is divided by a deep, not broad, nearly parallel- 

 sided fissure; the lateral portion on each side would be roun- 

 ded, except that there is an extremely slight production of 

 its hind part ; the preceding ventral plate is very peculiar, it 

 has in the middle behind a very large triangular depression, 

 the surface of which is coarsely asperate ; this part of the
