One female; Baracoa, Cuba, February 4, 1902. (William Palmer.) 

 [U. S. N. M.] 



As the female of this species has never before been recorded, a 

 description may prove of interest. 



Size medium; form elongate; surface smooth. Head somewhat 

 longitudinal, depressed, posterior portion constricted; interocular 

 region with several transverse depressions; occiput with a fine longi- 

 tudinal sulcus; eyes globose, very prominent; antennse not quite half 

 as long as the body, basal joint elongate-depressed. Pronotum longi- 

 tudinal, almost twice as long as broad ; transverse median depression 

 slightly in ad^^ance of the middle ; anterior portion with a transverse 

 depression immediately posterior to the anterior margin ; longitudinal 

 median carina slight. IMesonotum nearly six times as long as the 

 pronotum, subequal in width except for a shght anterior constriction 

 and a moderate expansion in the supra-coxal region. Metanotum 

 (with median segment) three-fifths the length of mesonotum; median 

 segment occupying about three-fifths the length of the whole segment. 

 Abdomen about equal to the thorax in length; four basal segments 

 longitudinal, equal in size; fifth dorsal segment somewhat inflated 

 apically; sixth segment compressed, tectate, carinate, slightly shorter 

 than the preceding segments in length ; seventh and eighth segments 

 subequal in size, tectate, carinate, the posterior portion of the carina 

 produced into a small rounded process ; ninth segment about equal to 

 the eighth in length, tectate, carinate, the lateral aspects each 

 bearing a low boss-like rounded swelling, apical margin with a very 

 shallow emargination, exposing the extreme tip of the supra-anal 

 plate ; cerci not half the length of the ninth dorsal segment, acuminate ; 

 subgenital opercule elongate, attenuate, apex decidedly acuminate, 

 reaching to the apex of the ninth dorsal segment. Anterior femora 

 and tibiae compressed, each almost equal to the mesonotum in length; 

 metatarsi equal to the remaining joints in length, superior surface 

 with a distinct foliaceous crest. Median femora and tibise somewhat 



ville, but is usually credited to Latreille. liatreille (Fam. Nat. Regn. Anim., p, 

 412, 1825) published simply the French form Bacterie, and included no species 

 under it. In 1807, Latreille (Gen. Crust, et Insect., Ill, pp. 87-88) divided the 

 stnus Phasma into two sections, the first of which he subdivided, and it was on 

 tlie second division of tlie first section that Lepeletier and Serville based their 

 genus. This division included three species, all of Fabricius, filiformis, ferula 

 and calamus. As the identification of these names is rather uncertain, I have 

 selected ferula as the type, as it is usually considered a synonym of arumatia 

 Stoll. wliich is based on a figure.
