TYPHLOLABIA. 



This name (ro^Xaq, la^ic) is proposed for the remarkable form 

 described by Philippi from Chili under the name of Forjicula ? larva. 

 According to Philippi the bead is as broad as long, tapering anteri- 

 orly, the angles rounded ; it is altogether eyeless; the antennae are ap- 

 proximate at the base, as long as the head and thorax, 30-40 jointed, 

 the first joint short, thick, cylindrical ; the second of equal length, ob- 

 conical, the third to the twelfth short cylindrical, the rest moniliform. 

 Prothorax much narrower than the head, and hardly half so long; 

 mesothorax a little broader, but narrower than the head, quadrate 

 with rounded angles ; the metathorax similar, but slightly larger. 

 Neither tegmina nor wings are present. The legs are very short, the 

 femora scarcely longer than the coxae and trochanters together, the 

 tibiae of similar length, compressed; tarsi one-Jointed, somewhat 

 shorter than the tibite. Abdomen long and slender, the joints of 

 about equal length, broadening up to the sixth, previous to which 

 they are lonye)- than broad; the forceps resemble those of Anisolabis, 

 which it seems most to resemble ; it is, however, exceedingly pecu- 

 liar in many points of its structure, and especially in the particulars 

 I have italicized above, in which it resembles no known Forficula-
