322 Mr. M. Burr's Ohseo'vations on The Dermatoptera. 



4 mm. 



Rah. Dardjiling; 1 (^, 1 ^ (-/. Harmand, No. 2854, 

 1890). 



This species resembles F. ru/icollis from Spain, but 

 the liead is not entirely black, the pronotum is square 

 not oblong, the wings are well developed, the elytra 

 unspotted, 



Forficula heelzehoh, Burr. 



I described this insect as a ChelisocJies in the Aunales de la 

 Soc. Entom. de Belgique, Tome xliv, p. 51 (1900), from a 

 single specimen ; in colour and appearance it resembles 

 Chelisochcs morio, which led me to range it in that genus, 

 but in the Paris collection I have been able to examine 

 a more complete series, and so have been able to see 

 more clearly the form of the second tarsal segment ; 

 there is no doubt that it is a true Forficula. The male 

 appears to be dimorphic in the form of the forceps ; the 

 form which I described as typical corresponds to the 

 varieties macrolahia, forcipata, etc. of our European For- 

 ficulaB, but there are some specimens with much shorter 

 forceps in the Paris collection, which are, perhaps, the 

 typical form ; from my description, the following words 

 must be suppressed, " hracchio sinistro {forciins) quam 

 dextro ])lus incwrvo " ; I was misled by the condition of 

 the single male which was the type, and the series in 

 the Paris collection shows that both branches of the 

 forceps are equally curved. 



It is easy to recognize by its black colour, with no 

 lighter markingfs.
