 to Simon 3 ) two separate species, the first identical with A. victims

7) As I only posses a single couple of A. striatus Sim. (from Paris, kindly 

 sent to ine by Simon himself), a J of 4. Lucasii Sim. (for which also I am 

 indebted to Simon) and another J, which I captured in Rome, and which ap- 

 pears to me to be a M. hamata C. Koch, though I cannot distinguish it from 

 "A. Lucasii'', it would be rash in me to make any objections to these determina- 

 tions of Simon. I ought however to mention, that tbe above-mentioned female 

 of A. Lucasii has two rusty red transversal bands on the pars cephalica, exactly 

 like C. Koch's figure of M. hamata, and which transversal bands Simon has him- 

 self observed in the male of "A. Lucasii", whereas the colour of the cephalothorax 

 in A. vicinus , as far as I can judge from Simon's description, appears to be 

 rather different. I have also in "A. striatus" J observed two similar transversal 

 bands on the cephalothorax, though fainter and more approaching to yellow. — 

 Perhaps the mandibles of the males may offer reliable features for determining 

 the forms in question, if they really be different species: it is unfortunate that 

 the descriptions furnished by Simon of these organs in two of them, A. striatus 

 and A. Iiamatus (cicinus), are so defective. In the S of A. striatus in my posses- 

 sion the mandibles, which are furnished with a strongly elevated edge along the 

 greater part of the outer side, are on the inner side emarginated, so as to leave 

 between them a narrow ob-ovate interval: at the apex they are broadly and obli- 

 quely truncated , and the inner corner of the apex forms a long and coarse 

 protuberance, which, at the extremity of the imperfectly developed claw-furrow's 

 anterior border, is drawn out into a large, lamellar tooth, which is broad and 

 rather obliquely truncated at the extremity, and slightly emarginated : these broad 

 inward- and downward-directed teeth form inferiorly, where they touch each 

 other, the border of the egg-shaped interval between the mandibles. At the 

 posterior margin of the claw -furrow, towards its apex, there is a little short and 

 coarse, conical tooth. Simon mentions three teeth at the claw-furrow in "A. 

 striatus" and "A. hamatus", of which the two situated on the inner margin are 

 in A. hamatus stated to be "elevees sur une sorte de tubercule, qui n'existe pas 

 chez 1 'autre espece." 



May not Salt. Guyonii Luc. (loc. cit., p. 156, PL 7, fig. 6) be the female 

 to A. Lucasii Sim.? It seems to me not improbable, that 8, erraticus Luc. is
