ART. 8. MILLIPEDS OF CENTRAL, AMERICA CHAMBERLIN". 7 



broader than the keels of the preceding segment, which surpass it 

 a little. Its caudal margin convex. Surface covered with numerous 

 setiferous granules as with the other tergites, with six tubercles along 

 the caudal margin bearing long setae, but these tubercles much smaller 

 than the corresponding cones characterizing PlatydesTtviis ; the tergite 

 not surpassing the anal valves which are not granular but bear numer- 

 ous short setae. The stemites are also all subdensely setose. Those 

 in the middle region very broad, the width nearly equal to the com- 

 bined length of the first two joints of the legs. In going forward and 

 backward from the middle region the sternites become progressively 

 narrower. Legs all shortly setose. 



Gonopods of male as shown in plate 1, figures 7 and 8. 



Length, 16 mm. ; width, 3.2 mm. 



Locality. — Guatemala: San Rafael, numerous specimens (O. F. 

 Cook, June 4, 1914) . 



Type.— C^it. No. 814, U.S.N.M. 



Family SIPHONOPHORIDAE.

11. SIPHONOPHORA BARBERI, new species. 



Plate 2, figs. 1-5. 



Yellow, of a usually reddish cast, with dorsum dusky and typically 

 showing a median longitudinal black line or stripe. Head rather 

 narrow, widest at base. Beak about equal in length to the head, a 

 little curved. The antennae are heavy and conspicuously clavately 

 enlarged, obviously thicker distally than at middle. The antennae 

 exceed the beak, the latter reaching to the middle of the sixth article 

 (see pi. 2, fig. 1). The coUum is subangularly widely excised in 

 fi'ont, sides converging forward, as shown in the figure. Pleurites 

 of anterior and of posterior regions as shown in plate 2, figures 2 

 and 3. 



Gonopods as represented in plate 2, figures 4 and 6. 



Number of segments, 68 to 82. 



Length, up to 30 mm.; the corresponding width, 1.2 mm. 



Locality. — Guatemala: Jocalo, many specimens (H. S. Barber). 



Type.— Csit No. 815, U.S.N.M. 



12. SIPHONOPHORA TELANA, new species. 



Plate 2, figs. e-8. 



Yellow, a little dusky, the head darker. 



Differs obviously from the preceding species in its more globose 

 head and much shorter rostrum, the latter shorter than the head, but 

 longer than in the Guatemalan S. globiceps Pocock (pi. 2, fig. 6).
