BARBADOS-ANTIGUA REPORTS 43 
Orthomorpha coarctata (Saussure) and Rhinocricus monili- 
cornis (Porat). The four species are given below. 
Superfamily SPIROBOLOIDEA 
Family Rhinocricide 
Rhinocricus monilicornis (Porat) 
Spirobolus monilicornis Porat, Bih. Svensk. vet.-akad. Handl., IV, no. 7, 
(1876), p. 31. 
Rhinocricus monilicornis Pocock, Jour. Linn. Soc. London, XXIV (1894), 
p. 499. 
Spirobolus heilprint Dollman, Proc. Acad. Nat. Sci. Phil., (1889), p. 127. 
Rhinocricus monilicornis Chamberlin, Bull. Mus. Comp. Zool., LXII, 
(1918), p. 200; Ann. Ent. Soc. America, XIII, (1920), p. 275. 
Eight specimens of this species were taken on Barbados by 
Prof. Stoner. The form had been previously recorded from 
this locality by Pocock (as cited above). R. monilicornis is also 
known from Haiti, Trinidad, Tobago and South America as well 
as from the Bermuda Islands, where it seems to be common. 
Rhinocricus arboreus (Saussure) 
Julus arboreus Saussure, Linnea ent., XIII, (1859), p. 351. 
Spirobolus (Rhinocricus) arboreus Karsch, Zeits. naturwiss., (1881), ser. 
avec iool), p. 8. 
Rhinocricus arboreus Pocock, Journ. Linn. Soc. London, XXIV, (1894), 
p. 493, pl. 38, f. 4. 
Rhinocricus arboreus Chamberlin, Bull. Mus. Comp. Zool., LXII, (1918), 
p. 197; Proc. U. 8. Nat. Mus., LXI, no. 10, (1922), :p. 9- 
This large milliped, originally described from St. Thomas Id., 
is also known from Porto Rico, where it is common, Culebra, 
St. Croix and Antigua. It has not been recorded from Bar- 
bados. Presumably it takes its name from the fact that it is 
said to ascend trees after the manner of certain: large species 
of the allied genus Dinematocricus of the Solomon and Fiji 
Islands and of the East Indies in general. 
Cubobolus politus (Porat) 
Spirobolus politus Porat, Ann. Soc. ent. Belg., XXXII, (1888), p. 243. 
Ehinocricus politus Pocock, Journ. Linn. Soc. London, XXIV, (1894), 
p. 488. 
This species is known only from the original description, 
which was based upon specimens from Antigua. In lacking 
scobina it apparently belongs to the group of species separated 
by the writer from Rhinocricus under the generic name Cubo- 
bolus (Proc. U.S.N.M., no. 10, LXI [1922] p. 10.)
