mination of one single, exsiccated male, given him by the British 

 Museum. The description is, in the whole, better than the figures 

 (comp. f. inst. fig. 4, showing the antennaj as possessing a short, 

 not excisting basal joint, and numerous joints in the flagellum, 

 while the description (p. 7) is correct). To enter into all details 

 of his description and figures, pointing out what is right, what is 

 erroneous and what it not mentioned, seems to me to be useless, 

 because I have given a representation which, I presume, may be 

 able to compensate for Saussure's treatise in all points, as it is 

 based upon much better material. I shall only point out that he 

 has produced a description, which is very good in many parti- 

 culars, but contains some very remarkable errors; it is, however, 

 to be remembered that he has examined but one single, exsic- 

 cated spemimen. Next it will be necessary to discuss the most 

 essential errors and differences from my own representation. 



P. 7 he says: »Les yeux manquent, et semblent être rem- 

 placés par une sorte de dépression ou par une petite pièce étroite 

 (o) qui est comme incrustée sur le bord antérieur de la tête, en 

 dedans de l'origine des antennes.» Examining his fig. 3 (with the 

 letter o) and comparing this with my fig. 3 (PI. 2) it is easily 

 discovered that his »pièce étroite (o)» is either the articular mem- 

 brane of the mandible or the upper exterior part of the mandible, 

 visible on the upper side of the head (see above). It becomes 

 more difficult to understand his representation of »labium infé- 

 rieur», both the description and the figure (fig. 6) showing the 

 3rd joints (of the labium) with their lobes as not cut off from 

 the 2nd joint and very small, though they, indead, are rather large 

 (comp. PI. 2, fig. 13) and very well defined, and he describes 

 and delineates the labial palpi as being 4-jointed, though they 

 are composed of but 3 joints. Quite inconceivable to me is his 

 representation of »labium supérieur, ou interne (endolabium)» (p. 26) 

 as a rather large, anteriorly broader plate, split from the anterior 

 margin a rather long way in the median line and with 3-jointed 

 lateral palpi! I must believe that a very bad preparation has been 

 the basis for this representation, for it seems to me to be quite 

 impossible that individual anomalies can exist to such a degree. 

 On the maxillae he has overlooked the large cardo, on the other 

 hand he has added in the description and the figures a chitinous
