2. Fam. LITHOBIINI. 



Laminae dorsales omnes manifesto? (alternae minores), integrae. 



Pedes longi, tarsis biarticulatis (in pedibus prioribus saepe indistincte) ; 

 ungues bini (in pedibus posticis saepe singuli), ungue majore processu 

 simplice, parvo armato. 



Antennae articulis multis vel permultis. 



Oculi ocellis paucis vel multis, aggregatis. 



Spiracula manifesta (sena). 



Palpi maxillares triarticulati, ungue armati. 



Laminae dorsales segmenti septimi atque octavi discretae. 



Sternum metameri quarti integrum ; prosternum ante integrum vel in- 

 dentes incisum. 



Pori excretorii in coxas quaternas (vel quinas) ultimas intrusi. 



For further explanation of the characters of this family I 

 refer to my preceding essays on the Lithobii (" Danmarks Sco- 

 lopendrer og Lithobier," Naturh. Tidsskr. 3 R. 5 B., p. 241, and 

 " Myriapoda Musaei Hauniensis ii, Lithobiini," ibid. 3 R. 8 B., 

 p. 281) and to the preceding pages of this paper. 



1. Gen. Litliobi us. 



Labrum liberum, in medio profunde incisum, dentatum, lateribus 

 fimbria lata et densa, e laciniis setiformibus, racemosis facta, instructis. 



Labium setis racemosis et simplicibus instructum, processibus labii sat 

 magnis. 



Palpi maxillares ungue tri- vel quinque-partito armati. 



Mandibular serie abbreviata setarum minorum, racemosarum pone setas 

 majores crenulatas armatae. 



Oculi ocellis paucis vel multis. 



Pedes omnes vel plurimi calcaribus armati, maxime unguibus binis 

 armati. 



Genitalium femineorum unguis intus excavatus, integer aut bi- vel tri- 

 lobus. 



The characters which are here given of the genus Lithobius 

 for the most part conform with those I have proposed in Myriap. 

 Mus. Haun. ii, Lithobii, p. 283, and the apparent great difference 

 arises solely from the introduction of my new terminology and 

 from the altered order of the parts of the mouth, both of which 

 my late investigations have made necessary. 



Lamina dorsalis 6, 7, 9, 11, 13 angulis productis. 

 Pedes anales ungue singulo armati. 

 Pori coxales in series plures digesti. 

 Genitalium femineorum unguis tripartitus. 

 Pedum analium coxa? calcare armaUu.
