Scolioplanes longicornis Meinert. 



This species was looked upon by its author as the probable type of a 



new genus. The prehensorial claws are very long and slender, and 



the basal tooth very small. That it represents a new genus is well-nigh 



certain, but it would be idle to name it until drawings can be made. 



Scolioplanes exul Meinert. 



This is a large specimen with a strong general resemblance to large 

 males of fidvns (robustus). The last pleurae are without pores except 

 close under the edge of the last ventral plate, where there is a large 

 porose cavity. Anal legs with the claw minute, almost rudimentary, 

 in this offering a strong contrast to the other American species known 

 to me. The anal legs are also very robust, much stouter than a 

 Califomian specimen of parviceps. 



Mecistocephalus breviceps Meinert. 



The type specimen is minus the cephalic lamina and antennae. There 



is another specimen labeled breviceps, but with no locality given. If 



the type was really collected at Nantucket the species must be very 



rare or local, for it seems not to have been found elsewhere. 



Mecistocephalus heros Meinert. 



It has been conjectured by Mr. Pocock that this species should be 

 added to the long list of synonyms of punctifrons. I have never exam- 

 ined carefully authentic specimens of punctijrons, but the form of the 

 prehensorial legs in the Cambridge specimen, especially the armature 

 of the coxa is different from that of Home's diagram of 

 There is no distinct tooth, only a rounded prominence at the distaL 



Himantarium indicum Meinert. 

 This specimen is in poor condition and has evidently been allowed 

 to dry at some time in its history. The antennae are distinctly attenuate. 

 The ventral pores are in a posterior, transverse, subreniform area three 

 or four times as broad as long. This area is scarcely depressed, but is 

 quite definite. Pleural pores are not visible. 



Himantarium tceniopse (Wood). 



Ventral pores in a small, round, impressed, posterior area. No 



pleural pores visible, but they may be concealed under the very broad 



last ventral plate, as is the case in the following species. 



Himantarium laticeps (Wood). 



The ventral plates appear to be unusually long. The pores are 



located about two-thirds back, in broad, short, transverse areas. Three-
