326 Mr. Shuckard'a Monograph of the Dorylidae, 



brought thence by the Rev. 1). F. Morgan, which appears to be the 



African representative of Typhlopone, with which it agrees in many 

 points of resemblance, but is sufficiently different to constitute an- 

 other »i'iiii>, should it eventually prove that Typhlopone is distinct 

 from Lubidus. This African insect agrees with Typhlopone in the 

 disproportionately large size of the head, which is also subemarginate 

 behind ; in having neither eyes nor ocelli; in the insertion of the 

 antenna (but which is within two deep fossulets, the inner edge of 

 which is not continued in a carina), and in their having but eleven 

 distinct joints and slightly clavated ; in the general form of the man- 

 dibles ; in the pi duncle of the abdomen, which is convex above ; and 

 in the apex of the abdomen being furnished with three minute teeth. 



I propose to call it 



Anomma, Shuck. 



for it differs from Typhlopone in the head being considerably widest 

 in front, at the base of the mandibles, which are elongate, forcipate, 

 much curved, with one large curved tooth at about half their length ; 

 in the thorax being constricted, especially at the sutural separation 

 between the pro- and mesothorax ; the latter and the metathorax very 

 narrow : the antenna and legs very slender, the latter long and their 

 femora not clavate, the peduncle of the abdomen very narrow, and 

 the segments but slightly constricted. 



Type Anomma Burmeisteri, Shuck. 



Sp. 1. A. Burmeisteri, Shuck. Entire length 6 lines. 



Nigro-piceus, nitidus, glaberrimus : antennis pedibusque rufo-piceus. 

 Brightly shining, perfectly smooth, pitchy black, with the antennas, legs, 

 thorax, ventral incisures and sides of the abdomen pitch)- red- 



The following are the proportions of this remarkable insect : 

 length of the head, including mandibles, '2| lines; thorax 1^ line; 

 abdomen, including the peduncle, 2^ lines. 



Mr. Thwaites, of Bristol, kindly communicated to me four spe- 

 cimens of Typhlopone, including two species distinct from those 

 previously described : they are 



15. Lab. (4 Typhlopone) Thwaitsii, Shuck. Length 3 — 5 lines. 



Rufo-testaceus, (rnandibulis antennisque rufo-piceis exceptis,) nitidus ; ca~ 

 p'xte antice sulcato et punctulato. 



Bright reddish testaceous and shining ; the head sparingly and not deeply 

 punctured, the channel between the carinas of the face continued about 

 one- third the length of the head and terminating gradually : the man- 

 dibles and antenna; pitchy red, the former having their teeth and the
