ventral side extremely large and completel}" enclosed by incubatory 



lamella\ \vhich are yisible from a dor.sal yiew at the sides of the body. 



Color of dorsal surface of thorax orange; head, abdomen, and 



incubatory plates white. The orange markings on the young within 



the marsupium giye an orange appearance to the yen- 



tral side of the body. 



Head distinctly bilobed. Eyes absent. Both pairs 



of antennse yisible from a dorsal yiew, the first pair 



consisting of perhaps three in- 

 distinct joints; the second pair 



extend half the length of the 



head and consist of a number 



of indistinctly defined joints. 



(Fig. 35.) 

 The segments of the thorax are more dis- 

 tinctly defined in some specimens than in 

 others. Along the lateral margins of the 

 thorax is a series of plates, a pair for each seg- 

 ment; these plates overlap the dorsal surface of 

 the thorax at the sides and are free on their 

 whole surface, being attached only at the 

 extreme lateral margin to the legs. (Fig. 36.) 



Similar plates are also found on the abdomen, where they meet five 

 from either side along the median dorsal line. The exact homology
