78 Dr. Schaum on four new Genera of Carabide. 
Acmastes Haroldii. (PI. IV. fig. 4.) 
A, niger, coleopteris subtilissime striatis.—Long. 93 lin. 
The eighth stria of the elytra, which in Heteracantha is close to 
the ninth, and follows it throughout the length of the elytron, recedes 
in Acmastes from the ninth behind the shoulder and approaches it 
again behind the middle, forming a feeble, externally concave sinus. 
A unique specimen of this remarkable insect has been taken by 
Baron Harold, of Munich, at Mogador, who kindly presented it to 
me. Although its sex is not ascertained, I have no doubt that the 
anterior tarsi are not dilated in the male. 
Puorticosomvs [trib. Harpalini]. 
Caput crassum, postice non attenuatum. 
Labrum subquadratum, fere truncatum. 
Palpi mazillares articulo ultimo preecedenti sequalis. 
Mentum dente medio parvo, membrana basali valde conspicua. 
Prothorax l\ateribus et angulis posticis rotundatis. 
Elytra sine striola scutellari. 
Tarsi antici in utroque sexu simplices, 
This genus belongs also to the group of Dapti (Cratoceride), having 
the anterior feet not dilated in the male, and a large head not con- 
tracted behind ; it is closely allied to Acinopus, and differs chiefly in 
its truncate labrum, and elytra without the scutellar striola. 
Phorticosomus felix, (PI. IV. fig. 5.) 
P. supra piceus, subtus rufo-piceus ; prothorace basi obsolete punctulato- 
rugoso ; elytris profunde striatis, striis levibus—Long. 53 lin. 
Habitat in Australia felici (Victoria) (D. Bakewell).
