CHAMBERLEN: MYRIOFODa OF THM atstkalian region. 81 



stripe not sharply set ofT, though od some tergites a brighter line each side of 

 median si ripe leaves a darker median area geminate by a longitudinal pale line. 

 Lege with darker markings, especially on femora and prefemora hut the 



definite arrangement of these is difficult to make out. Antennae yellow. 



First division of antennae with forty-two articles; second division with 

 near eighty) third division incomplete. 



Stoma saddles moderately elevated, stoma small, on most plates attaining 



and projecting into the caudal cmargination. 



First tarsus of first legs consisting of fourteen articles, the second of thirty- 

 two. First tarsus of second legs composed of eleven or twelve articles, the 

 second of thirty. First tarsus of third legs of ten, the second of twenty-nine. 

 None of tarsi present with first division ending in spines but last several pairs 

 of legs missing. 



Length, 11 mm. 



The type, not fully mature, seems to conform most closely to Gone- 

 thina, a genus previously known from the West Indies, though with- 

 out knowledge of the gonopods of the female this cannot be wholly 

 certain. From G. grenadensis differing in coloration and in the 

 coarser, more spinescent hair of the tergites as well as in other details. 



Diplacrophor, gen. nov. 



A genus of the Scutigerini resembling Lassophora of Madagascar in having 

 the tarsal pegs of the anterior legs alternating regularly in size. Unlike that 

 genus but agreeing with Scutigera in lacking any spines in the series of setae 

 of the prefemur of first legs. Agreeing also with Scutigera in the form and 

 general number of articles in the divisions of antennae. Differing from the 

 two genera mentioned in having spines of the middle tergites, which are 

 numerous and closely arranged on the margins, each accompanied by a short 

 hair-point as in Allothereua, etc.

Type — M. C. Z. 2,132. Solomons: Tulagi (W. M. Mann). 



Dorsum with a longitudinal light greenish grey stripe enclosing two black 

 lines between which is a somewhat orange colored median line; the stripe 

 limited on each side by an edging of black. Lateral region on each tergite 

 for the most part reddish but toward each side with two greenish grey spots 

 edged with black, the black color about the two connected. Dorsum of head 

 except laterally greyish green enclosing two longitudinal red stripes edged in 

 part with black. Legs greenish grey with deeper colored annuli of which
