ANCHASTUS. 397 



Hab. Mexico, Oaxaca, Tapachula (Hoge) ; Guatemala, Panzos, Teleman, and San 

 Juan in Vera Paz, Zapote {Champion) ; Nicakaua, Chontales (Belt). 



Eight specimens : — three (?) of the typical form, from Chontales, Teleman, and 

 Panzos ; four ( 6 ) of the var. a, from Tapachula, San Juan, and Zapote ; and one (?) 

 of the var. |3, from Oaxaca. The description, as regards colour, is chiefly taken from a 

 beautifully preserved specimen from Chontales. In the varieties the yellow and rufous 

 portions of the thorax are not clearly defined, being more or less merged into a general 

 rufous or rufo-testaceous tint. The third joint of the antennse is a little smaller than 

 the fourth. The prosternal sutures are channelled in front.

Monelasmus moratus, Cand. Monogr. Elat. iv. p. 334 \ 



Hab. Mexico, San Martin Tuxtla (Salle l ), Yucatan (coll. Janson) ; Guatemala, San 

 Jose (Champion). — Antilles, Grenada (H. II. Smith). 



The six examples of this species before me vary slightly in the extent of the black 

 discoidal patch on the thorax, this being sometimes very narrowly divided down the 

 middle so as to form two sinuous stripes. The thorax is almost square, being very 

 little narrowed in front ; the carina is short, almost straight, and (as viewed from above) 

 close to the margin. The third joint of the antennas is a little shorter and narrower 

 than the fourth, and twice the length of the second. The single example obtained by 

 myself was found on the Pacific coast. A. terminatus, Cand., from the island of 

 Guadaloupe, is an allied species ; it has the head similarly formed. 



13. Anchastus flavomaculatus. (Tab. XVII. fig. 28, s .) 



Elongate, rather narrow, feebly convex, slightly shining ; black, the head with a small spot in front, and the 

 prothorax with the lateral margins at the apex and a large subtriangular patch on either side behind, 

 orange-yellow ; the elytra with a pale flavous submarginal stripe, extending down the seventh and eighth 

 interstices to the middle and dilated inwards at the base ; the under surface black, the abdomen pitchy- 

 brown ; thickly pubescent, the pubescence yellowish-cinereous, blackish on the dark portions of the elytra. 

 Head closely punctured, moderately convex, margined in front ; antennse elongate, reaching nearly to the 

 middle of the elytra, the joints from the third moderately widened and serrate, 3 slightly shorter than 4, 

 2 very small. Prothorax as long as broad, subconical, rapidly and obliquely narrowing from about the 

 basal third to the apex ; the hind angles narrow, acute, slightly divergent, not carinate ; the surface 

 thickly, finely punctate, feebly canaliculate behind. Elytra moderately long, as wide as the prothorax at 

 the base, parallel to the middle and gradually narrowing thence to the apex, the apices separately rounded ; 

 finely but rather deeply punctate-striate, the interstices slightly convex, closely and subrugulosely punc- 

 tured. Beneath thickly, the propleurse and prosternum sparsely, punctured; prosternal sutures not 

 channelled in front. 



Length 7, breadth 2 millim. ( J .) 



Hab. Guatemala, Sinanja in Vera Paz (Champion). 



One example. This species differs from all the allied forms in the narrow, subconical 

 thorax, the hind angles of which are not carinate. The antennas are unusually
