WEST INDIAN CERAMBYCIDAE — CHEMSAK 211 



Holotype male (USNM 68224), allotype female, and 10 paratypes 

 (2 cT cf', 8 99) from Pricldy Pear Isl., Vixen Point, Virgin Gorda, B.V.I., 

 Apr. 14, 1956, and Apr. 6, 1958 (J. F. G. Clarke); additional specimens 

 not designated as paratypes include: 2 cf cT , Francis Bay, Saint Johns, 

 A.V.I., Mar. 25, 1958. 



The elytra of this species are pale with a little infuscation often 

 present at the base. M. insularum differs from M. necydalea (Fabri- 

 cius) by the usually concolorous elytra, narrower elytra! apices, 

 shorter pubescence of the antennal segments, and almost impunctate 

 pronotal disc. From M. pallida Fisher, it may be distinguished by 

 having the lobes of the eyes connected by a single row of facets. 



Methia impressicollis, new species 



Female: Form slender, small; color brownish testaceous; elytra 

 slightly paler; pubescence pale, sparse, short. Head slightly wider 

 than pronotum; eyes separated on vertex by less than diameter of 

 third antennal segment, separated beneath by a distance greater than 

 diameter of antennal scape, upper and lower lobes connected by a 

 single row of facets; antennae extending about four segments beyond 

 body, scape with strong apical tooth, segments densely clothed with 

 short suberect hairs along outside margin, suberect hairs of inside 

 margin longer. Pronotum broader than long, sides rounded, base 

 strongly constricted and broadly, deeply impressed transversely, 

 apex less strongly constricted, shallowly impressed; disc slightly con- 

 cave with an impressed, subglabrous, V-shaped area at middle begin- 

 ning near basal margin, surface scabrous, punctures fine, vague; 

 pubescence fine, mostly subdepressed; stridulatory plate of mesonotum 

 not grooved; prosternum narrowly impressed; episternum of meta- 

 thorax opaque. Elytra over 2K times as long as broad, extending 

 to about fourth abdominal segment; costae vague, punctm'es fine, 

 shallow, irregular, somewhat rugulose; pubescence very short, erect. 

 Legs with femora minutely rugulose, sparsely pubescent. Abdomen 

 with last sternite deeply V-shaped emarginate at apex. Length 5 mm. 



Holotype female (USNM 67325) from Little Harbor, Jost Van 

 Dyke, B.V.I., Apr. 1, 1958 (J. F. G. Clarke). 



This species differs from the other known West Indian Methia by 

 the V-shaped impression of the pronotum.
