viz. two large ones in front, a small one on either side, a little 

 retreating from the line of the large ones ; these four form the 

 first row ; those of second row two in number, one not far be- 

 hind each outer eye of first row ; those of third row (also two 

 in number) quite on sides of caput, and thus wider apart than 

 the outer eyes of the first row, and further from those of the 

 second row than these are from those of the first row. 



Two specimens of this minute species are in the Hope Col- 

 lection, Oxford [Hob, Novo Friborgo). They bear no small 

 resemblance to small beetles of the family Coccinellidse, since, 

 without close examination, it is difficult to see any division 

 between the cephalothorax and abdomen ; the concavity of the 

 fore margin of the abdomen is a curious and unusual struc- 

 tural peculiarity. Upon any general revision of the very nu- 

 merous family " Salticides," the present species should form 

 the type of a new subgenus ; for the present, however, I have 

 thought it best to describe it under the generic name Salticus 

 only. It is nearly allied to a well-marked group of the genus 

 Salticus which C. Koch has described as a genus (Bhanis) • 

 this group, however, has no claim to more than subgeneric 

 separation from the genus Salticus. 



Salticus bicurvatus, n. sp. 



$ . Adult. Length 2| lines. 



Cephalothorax elongate. Caput divided from thoracic por- 

 tion by a strong constriction, leaving the former nearly circular. 

 Thorax oval, narrowest behind, where it is truncate. Caput 

 and thorax of equal length. Colour black and shining. 



Eyes in three rows, each of the two forming the middle row 

 nearer to the exterior one on its side of the first row than to 

 that of the hinder row. 



Legs rather long, slender ; a few fine hairs and spines be- 

 neath tibise and tarsi of first and second pairs ; relative length 

 4, 1, 3, 2, but little difference between first and fourth and third 

 and second respectively : colour reddish brown, tarsal joints 

 darkest. 



Palpi short, not very strong. Being curled up beneath the 

 dried specimen, it was impossible to observe the structure of 

 the radial and digital joints or of the palpal organs ; the same 

 cause also precluded any observation of the maxillae and 

 labium. 



Falces very prominent, long, strong, and massive, rather 

 longer than cephalothorax ; their inner face flat ; extremities 

 straight and rounded on outer side ; when looked at in profile, 

 much arched above. Fangs as long as falces, sinuous, or con-
