The ventral pores in this species are numerous and conspicuous. 

 They are arranged in a transverse area extending entirely across the 

 plate immediately in front of the caudal margin, the area being mostly 

 in the form of a very low triangle with the apex caudad; more rarely, 

 it is in the form of an elongate, narrowly diamond-shaped area. This 

 character may be detected even in very young specimens. 



The type of G . georgianus I find to be a medium sized female agree- 

 ing fully with bipundiceps. Meinert is in error in saying no anal 

 pores are present. The anal pores in grown individuals are usually 

 to be seen well only in lateral view. The opening lies in a depression 

 and varies considerably in size, and, because of expansion of the canal, 

 more so in appearance than in actuality, sometimes appearing very 

 large where the tegument is transparent. A. latro of Meinert is based 

 upon an individual in which the pores appear large, but it seems 

 clearly this species. In other cases the folding of the tegument may 

 so cover the pores that they are detected with difficulty and might 

 be supposed to be absent (A. georgianus Meinert). Of A. latro I 

 have not seen the original types; but in the Museum of Comparative 

 Zoology there are four specimens determined by Meinert which are 

 doubtless equally authentic. 



Arenophilus watsingus, sp. now 



Strongly attenuated caudad, less strongly cephalad; in general 

 very sparsely provided with straight hairs which are moderate to long. 



Body and legs yellow, the antennae a little darker. Head and pre- 

 hensorial feet with prosternum light reddish brown. Cephalic plate 

 much longer than wide (31:22), six times longer than the exposed 

 portion of the basal plate in type specimens, but varying somewhat 

 in others; subtruncate anteriorly and posteriorly, the sides nearly 

 straight excepting at anterior and posterior ends where they bend 

 obliquely mesocephalad and mesocaudad respectively, the caudal 

 oblique portion being longer than the anterior. Frontal plate not 

 discrete. Cephalic plate on caudal portion with two long sulci which 

 run cephalad from caudal margin and diverge a little; glabrous or 

 nearly so, there being a very few bristles (see Plate 1, fig. 1). 

 Exposed portion of basal plate at middle considerably more than
