578 STUDIES IX AUSTRALIAN ENTOMOLOGY, NO. XII., 



testaceous; anteniij\3 testaceous, slightly infuscate towards apex. 

 (Elvtra piceous near suture and narrowh^ so near each lateral 

 margin, each elytron testaceous from shoulder to apex, this testa- 

 ceous part spreading inwards to the second interstice a little 

 before the discoidal seta and more or less interrupted by an 

 external cloudy dilatation of the sutural dark patch a little 

 behind the middle; apical declivity testaceous between recurved 

 striolai, more or less infuscate along course of recurved striolas). 



Head shagreened, front lightly convex in middle. Prothorax 

 broader than long (0-4 x 0'68mm.), widest before middle, declivous 

 to base; apex very lightly emarginate; anterior angles obtuse, 

 not prominent; sides lightly rounded, gently narrowed posteriori}^ 

 subsinuate near base, basal angles marked, obtuse at summit; 

 base cut obliquely forward on each side to basal angles; a strongly 

 impressed arcuate transverse line (reaching base at each end) 

 above peduncle. Elytra truncate-oval (1-6x1 mm.), widely 

 rounded at apex, subparallel on sides; two inner striae well marked 

 on disc, third weaker, others faint or obsolete; a short strongly 

 raised lateral interstice extending backwards from posterior third 

 on each elytron. Length 2-3-2-7, breadth 0-8-1 mm.

This small species would, according to the tabulation I formerly 

 made of the Australian species of Tachys, come into section '7." 

 It is allied to T. infuscatiis, Blkb., which is unknown to me in 

 nature, but I have submitted it to the Rev. Thos. Blackburn, 

 who writes that it is not conspecific with T. infuscatns, being 

 "not unlike in colouring, but darker, very much narrower and 

 more convex, pronotum considerably less explanate and less 

 turned up at basal angles, stride of elytra much stronger." 



Tachys doddi, n.sp. 



Oval, depressed. Black; prothorax with a narrow piceous 

 margin along base; elytra 5-maculate, the maculae pale, the 

 anterior one of each elj^tron small, reniform, longitudinally placed 

 a little behind humeral angle, not touching base or lateral margin;
