Pselaphidae of tlw Howitt Collection. 9 



transverse impression, bounded on the iiinder niurp^in by two 

 distinct oblique obtuse ridges, which do not quite meet. From 

 some directions the abdomen appears feebly longitudinally im- 

 pressed from base to apex, with the ridges like two distinct and 

 fairly distant tubercles. The spines on the under surface of 

 the head are thin and acute. 



The ventral impressions on the males of this genus are 

 the most satisfactory characters for the identification of the 

 species, and in King's descriptions are not even mentioned. 



I believe the Howitt specimens to be correctly named, but 

 the species of this genus so strongly resemble each other 

 that King may have been mistaken, and it is very desirable 

 that the ventral impression of the type should be examined 

 and described. 



Rytus /functatus, King (now Rytus suhulatus King). 



King's label, '" Rytus punctatus, R.L.K. (Tyrus subulatus), 

 Paramatta." 



First described by King as Tyrus suhulatus, but later men- 

 tioned as the type of the (then) new genus Rytus, but the 

 name altered, without sufficient cause, to punctatus. 



As the essential features of the species are re-described^ by 

 Raffray, there is no need to re-describe the Howitt specimen. 



King recorded the types as from Parramatta and Dunheved ; 

 the Howitt specimen is from Parramatta; a co-type in my own 

 collection is from Dunheved, and I have others from th.e 

 Richmond River and Windsor. 



Rytus vicforiae^ King. 



King's label, " Rytus victoriae, R.L.K." 



Type ?. Reddish castaneous, head and prothorax darker, 

 palpi and tarsi flavous. With rather long pale pubescence. 



Head rather long, with small punctures, with a fairly deep 

 fovea of moderate size close to each eye. Antennary tubercles 

 fairly prominent. Antennae passing middle coxae,,, first joint 

 as long as second and third combined, second slightly longer
