I04 REPORT OF NEW JERSEY STATE MUSEUM. 



of these plates and of those on fourth segment toothed, teeth 

 on genital segment plates being considerably larger and coarser. 

 Genital plates not routing over ventrally in scroll as in Cecrops, 

 but flattened to very edge. Abdomen similar to Cecrops, lateral 

 lobes prolonged sidewise and backward so their edges coincide 

 nearly with those of genital segment plates. Abdomen length 

 plus these plates about twice that of genital segment in front of 

 abdomen. Lobes also set w^ith fine teeth along their edges, and 

 not rolled at margins, but fiat. This space between them and 

 genital segment, in which egg-string;s are coiled, not as thick 

 dorso-ventrally but wider than in Cecrops, thus accommo- 

 dates about same length of egg-strings, twenty or thirty times 

 body length. Strings about same diameter and eggs fully as 

 numerous. 



First antennae three-jointed, joints diminishing regularly in 

 diameter and 'in length from base outward, also very sparsely 

 armed with set?e. Second antennae large, three-jointed, projects 

 well in front of carapace, terminal joint very powerful, strongly 

 curved claw buried its entire length in flesh of host. Mouth-tul3e 

 broadly conical, similar to that in Cecrops, mandibles projecting 

 through opening at its tip, armed with square teeth on their 

 inner margins only. Second maxilke in form of short conical 

 knobs, apparently without joints, spines or rudimentary exopods. 

 in size less than one-fourth length of mouth-tube. First maxil- 

 lipeds two-jointed, both joints exceptionally stout and terminal 

 slightly longer. Terminal claw short, wide, heavily fringed with 

 stout spines, and accessory claw in form of large spine. On 

 ventral surface of joint opposite accessory claw a raised knob 

 covered with small spines. Second maxillipeds swollen, basal 

 joint miiich longer than terminal claw, on its inner surface two 

 pairs of knobs, one near base of terminal claw and other near 

 its own base. Claw when closed lies between two knobs of each 

 pair. Legs all biramose, rami transformed into flattened laminae 

 without plumose setae, and those of first two pairs two-jointed, 

 while third and fourth pairs with but single joint. Color uni- 

 form, light yellow without any pigment markings. Claws and 

 chitin ribs which strengthen carapace darkened to brownish hue. 

 Total lensfth 20 mm.
