4. Agriotes virgatus. (Tab. XXII. fig. 20, var.) 



Agriotes virgatus, Cand. Monogr. Elat. iv. p. 368 \ 



Hab. Mexico, Toxpam, Cordova, and Santecomapan in Vera Cruz, Oaxaca {Salle l ), 

 Almolonga, Juquila (Hoge), Atoyac in Vera Cruz (H. H. Smith). 



Not uncommon in Mexico, whence we have received a long series. The form with 

 the thorax rufous or flavo-ferruginous (var. b of Candeze) is much more abundant than 

 the type. A. virgatus may be known from most of its allies by the long, oblique, 

 broad, yellowish vitta on each elytron, the vittse and the suture being clothed with 

 pallid pubescence ; the thorax is longer than broad. A specimen of the var. b from 

 Cordova is figured. 



5. Agriotes pulcherrimus. (Tab. XXII. figg. 21, <J ; 22, var. ligatus; 23, var. /3.) 



Agriotes pulcherrimus, Cand. Monogr. Elat. iv. p. 364 l . 



Hab. Mexico, Volcan de San Martin \ Tuxtla, Juquila (Salle), Almolonga, Cordova 

 (Hoge); Guatemala, Purula in Vera Paz (Champion). 



Tar. a. The sutural and discoidal stripes of yellowish-cinereous pubescence narrower and more sharply 

 denned. (Fig. 23.) 



Agriotes ligatus, Cand. Compt. Rend. Soc. Ent. Belg. 1878, p. cxciii (Elat. Nouv. ii. p. 48) 2 . 

 Hab. Mexico (coll. Janson) ; Guatemala 2 (Salle ; coll. Janson). 



Var. (3. The prothorax obscure rufous or black, with the two fusco-pubescent marks coalescent and extending 

 downwards on the middle of the disc so as to form a subcruciform patch ; the submarginal cinereo- 

 pubescent elytral vittse narrow and confluent before the apex. (Fig. 23.) 



Hab. Guatemala, Coban in Vera Paz (Conradt). 



With a long series of specimens it is not possible to separate A. ligatus from A. pul- 

 cherrimus, the two insects differing only in the relative width of the stripes of pallid 

 pubescence on the elytra. In the numerous examples from Purula, as well as in some 

 of those from Mexico, these stripes are even broader than in the type ( 6 ) of 

 A. pulcherrimus ; and in one of the two specimens from Tuxtla they are very little 

 wider than in A. ligatus. The insect varies in colour from black to brown. The 

 thorax in some specimens is ferruginous, with a broad transverse black patch before 

 the middle, which is divided along the centre and narrowed outwards, in others black 

 or rufous; it is densely, finely punctate, with two large blackish-brown or fusco- 

 pubescent spots before the middle, and the rest of the rather coarse dense pubescence 

 yellow or yellowish-cinereous. The suture and a stripe on the outer part of the disc 

 of the elytra are clothed with yellowish or whitish pubescence, the rest of the pubes- 

 cence being fuscous or blackish-brown : in some specimens these stripes become so 

 extended as to leave a very narrow fusco-pubescent space on the disc of each elytron. 

 The pubescence on the under surface is entirely yellowish-cinereous. In the two
