 Sj.yirostreptus (/raclli^ies, Newp. loc. cit. p. 200, from the Philippine 

 Islands, is based upon a specimen of tS/jirobolas, and has beeu 

 redescribed as Spirobol as juloides by Karsch,Zeitschr. Naturwiss.

 Sjnrobohfs pulvillaius and sl>uilli))ius, Newport, loc. cit. pp. 268, 269, 

 are synonyms ; the species has been recharacterized as giganteus 

 by Porath, tEfv. Vet.-Ak. Furh. 1872, p. 17, and asligukitus by 

 Voges, Zeitschr. wissen. Zool. 1878, pp. 180, 181. 

 It is extremely common, at Lagos. 

 Spiroholus caudatus, Newport, loc. cit. p. 269, has been redescribed 



as P. hetiis by Karsch, Zeitschr. Naturwissen. (3) vi. p. 70. 

 Spirobolus 7'oseus (Gervais), Ins. Apt. iv. p. 181 (18-17), of which a 

 co-type is in the British Museum, has been redescribed as Sp. 

 costulatus by Porath, Bih. Sv. Yet.-Akad. Handl. iv. no. 7, p. 31. 

 Sj)irostre]>tns corculus, Butler, Ann. Mag. Nat. Hist. (5) ix. p. 330 

 (1882), belongs to the same category of species as the other 

 known Madagascar forms. It is based upon young specimens, 

 and may be easily recognized by the two wide longitudinal 

 flavous bands which run throughout the length of the body ; the 

 head is flavous, with a conspicuous black band between the eyes. 

 Loc. Betsileo, Madagascar. 

 S2>i>'0sti'e2>tiis Cowani, Butler, loc. cit. p. 328, is in reality a Spiro-

 Spirostreptus avernns, Butler (Ann. Mag. Nat. Hist., June 1876, 

 p. 445), from Kodrigucz, is a small, slender, luliform species of 

 Spirobolus. There are tour labral pores on each side ; the eves 

 are separated by a space about equal to three times a diameter ; 

 the antenna) are very short ; the collum laterally resembles that 

 of a Sjjiroatripius, extending as low as the second tergite. The 

 posterior half of the tergites is elevated and smooth above ; the 

 median portion is marked irregularly with crcscentic impres- 

 sions ; the pores are situated behind tlie sulcus on the posterior 

 part of the tergites. Scobina absent. The anal tergite is pro- 

 duced into a triangular tail, which overhangs the valves ; 

 valves with margins not compressed. 



Sp.globulanus ofKarsQh, from the Comoro Islands, is very close 

 to this, but appears to differ in the number of labral pores. 

 Spirostrejytus sorornus, Butler (ibid.), from Kodriguez, is a Sjnro- 

 bolus related ai)parently to GoUsii of Porath, but with the median 

 part of the somites scarcely sculptured above and the copulatory 

 feet of a different form. 



It is closely allied to S. comorensis of Karsch, and to lumbri- 

 cinus of Gerstiicker, both of which have been recorded by Karsch 

 from Mayotte. 

 Spirost reptus simidans, Butler {ibid.), from Kodrigucz, is based upon
