Two examples, females. The species is generically distinct from 

 the restricted genus HarpaluSj, with ^vhich it agrees in the im- 

 portant characters of a single discoidal elytral pore and in form 

 and facies. It differs in the edentate mentum which has a further 

 peculiarity in having a transverse depression immediately behind 

 the site of the usual tooth which depression is quadripunctate, 

 two of the punctures (at least) having tactile setae, like those 

 at each basal angle of the mentum. The fine suture extending 

 from the frontal foveae to the inner margin of the eye is also 

 an important character which I do not find in any true Har- 

 palus. Satisfactory generic characters cannot be drawn up without 

 a knowledge of the </' and the form of the ligula.

Karin Asciuii Gheba. A single example, apparently belonging 

 to this genus. 



179. Trichotichnus Birmanicus, n. sp. 



T. (Harpalo) congruo (Motsch. Harold) proximo affinis; dif- 

 fert inter alia thorace utrinque basi vix punctate. Harpalo lae- 

 vkolli (Dufts.) similis; subaenescenti-niger, politus, partibus oris, 

 antennis et pedibus rufo-testaceis. Gaput laevissimum, sutura 

 frontali acuta, utrinque oblique usque ad oculi marginem pro- 

 longata. Oculi mediocriter prominentes. Thorax panilo trans- 

 versus, antico sat fortiter rotundatus, postice sinuatim et me- 

 diocriter angustatus, angulis posticis rectis, fovea utrinque basali 

 parva parumpunctata (caetera laevis). Elytra oblongo-ovata, sub- 

 opalescentia, apice oblique sinuata, acute striata, interstitiis panilo 

 convexis, 3.'° panilo post medium unipunctato. — Long. 7 millim. 



Karin Gheba, alt. 900-1100 m. Two examples. 



Agrees, in all the characters found to be of generic value in 

 the Harpalinae, with the genus Trichotichnus^ Morawitz, founded
