ever, in the measurements, the posterior femora of the type being 

 eleven millimeters shorter than that of the specimen collected by Dr. 

 A. Donaldson Smith, in the collection of the Academy. 



Genus BACTRODODEMA St&l. 

 1859. Bactrododema Stal, Ofver, K, Vetensk.-Akad. Forhandl., 1858, p. 308. 

 . Type.— 5. tiarata Stales 



Bactrododema miliaris Bolivar? 



1890. B[actrododema] miliaris Bolivar, Jornal Sci. Math. Phys. Nat. Acad. 

 Real Sci., Lisboa, 2a ser., I, p. 87. [San Thom^, West Africa.] 



One female; Gaboon river. West Africa. (Dr. Henry A. Ford.) 

 [A. N. S. Phila.] 



This specimen does not wholly agree with Bolivar's description of 

 the species, differing in the bowed median and posterior femora, in 

 which respect it approaches B. welwitschi Bolivar (ibid., p. 88) from 

 Golungo Alto, but from that is separated by the character of the ceph- 

 alic spines and the longer wings. Westwood's cestuans appears to be 

 a very distinct form. 



Genus TIRACHOIDEA Brunner. 



1893. Tirachoidea Brunner, Ann. Mu^. Civ. Stor. Nat. Genova, 2a ser., XIII, 

 p. 83. 



Included Phibalosoma cantori Westwood, Ph. Mjpharpax Westw., Ph. 



tiarchus Westw. and Cyphocrania tamyris Westw., of which the first, 



cantori, may be taken as the type, as both sexes are known. 



Tirachoidea cantori (Westwood). 



1859. Phibalosoma Cantori Westwood, Cat. Orth. Ins. Brit. Mus., I, p. 74, 

 PI. XXXVII, fig. 1 (J'), and PI. XXXVIII, fig. 1 ( ? ). [Malacca.] 



One male ; Trong, Lower Siam. (Dr. W. L. Abbott.) [U. S. N. M.] 

 This specirnen agrees perfectly with Westwood's figure, except that 



the ninth abdominal segment is very slightly shorter and the two arms 



of the same less curved. 



23 As some orthopterists do not recognize this genus as distinct from Palophus 

 Westwood, and both names being ostensibly published in 1859, the author ex- 

 amined the works containing each, to ascertain, if possible, which had priority. 

 St&l's work was presented for publication in 1858, but obviously did not appear 

 until 1859, the copy of the work in the librarj^ of the Academy having been re- 

 ceived May 22, 1860 ; and while the Proceedings of the Entomological Society of Lon- 

 don give no clue as to the date of receipt of the 1858 volume, the 1859 volume is 

 stated to have been received during 1860. Assuming the numbers to have a))- 

 peared regularly, this would place the 1858 portion as appearing during 1859. 

 Westwood's work, bearing the date June 1, 1859, on the Preface, was received 

 at the Academy January 10, 1860, but is not mentioned in the Proceedings of 

 the Entomological Society of London until August 6, 1860. In the Proceedings of 

 the. Boston Society of Natural History, the 1858 Ofversigt is entered as received 

 between April and June 30, 1860. From the above it will be seen that the dates 

 of publication are very close, and the question of priority is one I am unable to 

 settle at present.
