528 SEEEICOENIA. 



29. Agriotes quadrilineatus. (Tab. XXIII. fig. 19, $ .) 



$ . Elongate, narrow, convex, subopaque ; brown, the head, except in front, a broad indeterminate space 

 along the disc of the prothorax extending from the apex to near the base, the prosternum, propleurae, 

 and metasternum piceous ; the antennae blackish -brown, with the basal joint rufo-testaceous, the legs 

 testaceous ; above densely pubescent, the pubescence on the second and fourth interstices of the elytra, 

 and also that on their exterior margin, brown, that on the rest of the upper surface pale yellowish-grey, 

 whitish along the suture, the hairs on the disc of the prothorax transversely arranged on either side of 

 the median line ; beneath densely clothed with whitish pubescence. Head densely punctured ; antennae 

 short, not reaching the hind angles of the prothorax, joint 3 slightly longer than 2, and a little shorter 

 than 4. Prothorax very much longer than broad, subcylindrical, a little rounded at the sides, the latter 

 arcuately converging in front and slightly converging behind; the hind angles moderately long and 

 divergent, not carinate ; the surface densely, finely punctate, deeply canaliculate behind ; the base with 

 short but distinct incisures ; the marginal carina almost obliterated at the middle. Elytra two and 

 two-thirds longer than the prothorax, rapidly narrowing from about the basal third, attenuate behind ; 

 punctate-striate, the interstices feebly convex and rugulosely punctured. Beneath closely and finely, the 

 prosternum and propleurae more sparsely, punctate. Hind coxal plates slightly widened in their inner third. 

 Length 9|, breadth 2f millim. 



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



One specimen. This insect slightly resembles A. fulvescens ; but it is considerably 

 narrower than that species, and has the elytra more attenuate and the hind angles of 

 the thorax much less produced. The pubescence on the under surface and along the 

 elytral suture is whiter than that on the other parts of the body ; the brown hairs on 

 the second and fourth interstices form two well-defined stripes on each elytron. 



30. Agriotes cruciatus. (Tab. XXIII. fig. 20.) 



Moderately elongate, narrow, rather convex, slightly shining; black or blackish-brown, the prothorax 

 testaceous, with a large cruciform black or blackish-brown patch on the disc not quite reaching the 

 base, the basal joint of the antennae and the scutellum sometimes obscure testaceous ; the legs brown, the 

 femora sometimes paler ; the under surface much paler than above, the propleurae entirely testaceous ; 

 above and beneath thickly pubescent, the pubescence on the prothorax partaking of the ground-colour, 

 that on the elytra cinereous along the suture and at the sides, and fuscous or fusco-cinereous on the rest of 

 the surface— in one specimen ( $ ) uniformly yellowish-cinereous, the under surface uniformly yellowish- 

 cinereous-pubescent. Head densely punctured ; antennae extending to some distance beyond the hind 

 angles of the prothorax in the male, shorter in the female, joints 2 and 3 equal, 3 shorter and narrower 

 than 4. Prothorax about as long as broad, the sides rounded anteriorly and subparallel behind ; the hind 

 angles moderately produced, acute, slightly divergent, and not carinate; the surface densely, finely 

 punctate, canaliculate behind, and with indications of a smooth median line ; the marginal carina distinct 

 at the base and apex only. Elytra about three and one-fourth times the length of the prothorax, 

 narrowing from the basal third in the male, more parallel in the female, the apices rather sharp ; punctate- 

 striate, the interstices flat and rugulosely punctured. Beneath closely and finely, the propleurae very 

 sparsely, punctate, the prosternum with coarser punctures. Hind coxal plates slightly widened in their 

 inner third. 



Length 6f-8|, breadth 1|-2| millim. ( £ ? .) 



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



Found in plenty by myself at Chiacam. This remarkably distinct species somewhat 

 resembles A. pulcherrimus, but it is very much smaller and narrower, and has a shorter
