330 NEW MYRIAPODS FROM INMANA. 



4. Trichopetalum boUmani, spec. nov. Plate xii. 



This species resembles T. glomenititm, but differs in the following 

 respects : 



Light horn color; leg bearing segments about forty-live. Legs 4G to 

 50. Antennai relatively more slender. The third joint of the antenna^ 

 is .Sd*""" long and .083'"'" wide at proximal end, and .119"'™ distad, being 

 therefore about eight times as long as wide. T. glomeratum has the 

 corresponding joint about four times as long as wide. The other joints 

 are proportionally slender. The fourth and fifth joints of T. bollmani 

 are more nearly equal than the correspondingjoints are in T. glomeratum. 

 In the former the length is, respectively, .03""'" and .72"""', in the hitter 

 _24mm ami .33™™. The former has the fourth joint straight instead of 

 kneed as in the latter. The length of the joints of the antennie, except 

 the first, is, 2nd, .34™™, 3rd .84™'", 4th .03"'™, 5th .72™™, 6th .41™™, 7th, 

 .24™™. The caudal subsegments are swollen and give the body of the 

 animal a ridged appearance. Length. 17™™; diameter, 1.5™™. 



During the months of XDVciuber and December, 1885, this species 

 was found in small numbers, in May fold's cave, 5 miles northwest of 

 Bloomington, Ind. This cave is about a I'ourth of a mile in length, 

 and is simply the outlet of an underground stream. Ten feet high at 

 the entrance, it gradually decreases in size to a slit in the rock too small 

 to admit the body of a man. The floor is covered with fragments of 

 rock fallen from the ceiling under which the specimens furnishing this 

 description were found. There are seven specimens in the museum. 



5. Lisiopetaliini eudasym, spec. uov. 



Body and head deep brown, almost black, with lighter mesodorsal and 

 laterodorsal stripes. Each scutum, except a few nearest to the head, 

 has twenty-six ridges situated upon the caudal two-thirds of its dorsal 

 surface. Fourteen of these ridges are comparatively small and twelve 

 larger. Each of the larger ridgcs extends caudad in an acutely-conical 

 bristle-tij)ped point, which projects over the following scutum. Two 

 small ridges are i)laced in the mesodorsal stripe ; laterad to these on 

 either side six larger ridges alternate with six smaller; three larger 

 ridges lie between the mesodorsal and laterodorsal stripes, one lies in 

 the laterodorsal stripe and two ventrad. Immediately below the anal 

 scutum and on either side of the meson are situated two very coarse 

 setae, out of which two fine set<e grow. The eye-patches are triangular 

 with convex margins and each contains forty-six ocelli. Antenna? cou- 

 colorous with the body and pilose except the first joint, which is lighter 

 and not i^lose. All the joints distad of the first have a ring of lighter 

 color distad ; the four joints distad of the first are moderately clavate 

 and subequal ; the sixth is more decidedly clavate and a little more than 

 half as long as the fifth ; the distal joint is a convex cone. The antenna? 

 are kneed at the junction of the third and fourth joints. Head punctate 

 and densely- pilose. Labrum deeply emarginate. Legs pdose, yellowish 

 white, darker distad. Leg bearing segments, 58. Legs, 102. Length,
