CATALOGUE OF ORTIIOrTEROUS INSECTS. 



hiud leg (the right one being broken off) of the unique 

 specimen now in the British Museum having been lost and 

 subsequently reproduced of a smaller size than the other 

 legs, with the tarsus imperfectly developed. The insect is 

 very long, slender, and cylindrical. It is a male, and is 

 entirely destitute of spines or tubercles. Its proportions are 

 as follow : — Head, hn. li ; proth. lin. If ; mesoth. lin. 1 1| ; 

 metath. lin. 7i; abdom.lin. 15i + lin. 5}=\m. 20f. The 

 meso- and metathorax are slightly dilated at their hind part; 

 the abdominal segments are rather narrowed in the middle ; 

 the eighth segment is considerably longer than the ninth, 

 which is rather square above, emargiuate behind, with two 

 elongated clavate anal styles porrected obliquely beyond the 

 extremity of the body ; the three terminal ventral segments 

 are dilated, and do not extend beyond the middle of the 

 eighth dorsal segment. The legs are very slender and quite 

 simple. 



Dr. Burmeister suggests that this insect may be the 

 female of his Bacteria tridens. Desirable as it is to deter- 

 mine the sexes of these insects, and justifiable to suggest 

 the sexual identity of insects described as distinct where 

 sufficient evidence exists of such a relation, it is clearly un- 

 advisable to attempt this where no grounds exist to enable 

 the student to arrive at such a conclusion. In the present 

 instance we have a male insect regarded as the female of 

 another species, whereas the description "corpus filiforme" 

 should have suggested to Dr. Burmeister that the insect 

 was a male.

Obs. The typical specimen of this insect in the Paris 

 Museum wants the fore legs ; the middle and hiud pairs of 

 these organs are comparatively short ; the body is long and 

 slender, with the following proportions: — Head, lin. \\; 

 proth. lin. 1 ; mesoth. lin. 6 ; metath. lin. 5^ ; abdom.

Hab. In Chili. 



The male of this species preserved in the Paris Museum 

 has the following proportions : — Head, lin. 3 ; proth. lin. 2\ ; 

 mesoth. lin. 13 ; metath. lin. 9; abdom. unc. 2^. The head 

 has two erect horns between the hind part of the eyes, and 

 the abdominal segments have a small lobe in the middle of 

 the hind margin of each. 



Obs. The Prisomera ? phyllopus of Mr. G. R. Gray (Syn. 

 Phasm. p. 16), — a native of South America, in the Ilopean 

 Collection, shortly described as " olivaceum, thorace sca- 

 briusculo, femoribus quatuor posticis basi et apice perfolia- 

 tis," — considered by Dr. Burmeister as identical with Bac- 

 teria spatulata, is quite distinct.
