EUPLECTINI 101 



Head with the anterior union of the longitudinal vertexal sulci obso- 

 lete, rudimentary insularis 



(1.2-1.4 mm.; both sexes known; Guadeloupe, Leeward Islands) 

 6. Base of each elytron with no foveae (?!) ; known only from Guate- 

 mala solitarius 



(1.25 mm.; sex of unique type unknown) (Cerro Zunil, Guatemala) 

 Base of each elytron with three foveae; known only from Colombia 



inhonestus 



(See male key) 



RafTray (1903, 1908) does not list guatemalenus Sharp, and thinks that 

 solitarius Sharp is probably not Euplectus. However Sharp (1887, p. 37) 

 compares his guatemalenus with Euplectus signatus Reichenbach of Europe, a 

 well known species. If Sharp's two doubtful species be included, the neotropical 

 forms may be listed: 



exiguus Rafifray. 1904. Grenada, Windward Islands. (VIII) 

 guatemalenus Sharp. 1887. Guatemala. (Euplectus?) (X?) 

 illepidus Raffray. 1904. St. Vincent, Windward Islands. (X) 

 inhonestus Raffray. 1898. Colombia. (X) 

 insularis Raffray. 1908. Guadeloupe, Leeward Islands. 

 signifera Reitter. 1882. Venezuela, [nee signifer) (VII) 

 solitarius Sharp. 1887. Guatemala. [Euplectusl) (X?) 



The Roman numerals denote the Raffray group number (1904), and it is 

 notable that the tenth group is wholly neotropical, and secondly that the 

 Antilles have the greatest number of species. 



BARROEUPLECTOIDES new genus 



Euplectini having (1) vertex 4-foveate; (2) eleven-segmented antennae 

 which are widely separated, and with a two-segmented club; (3) maxillary 

 palpi very small, four-segmented, first minute, second subtriangular; third 

 subspherical, nearly as long as second and of about same width; fourth seg- 

 ment as long as second and third united, ovate; (4) pronotum subquadrate, 

 lateral margin denticulate at basal third; lateral fovea each side at level of 

 marginal denticule; median fovea at basal third; no trace of transverse sub- 

 basal sulcus connecting the three subbasal foveae; disk with a median fovea; 

 (5) each elytron with two basal foveae; no subhumeral fovea but a well- 

 developed longitudinal subepipleural carina and sulcus; (6) abdomen five 

 visible tergites, of which the first three are subequal in length and the fourth 

 much longer than the preceding; six stemites in the female sex (male un- 

 known), second, third, fourth and fifth subequal; tergites with no basal 

 carinae; (7) middle coxae contiguous; (8) posterior coxae contiguous; (9) 

 prostemum not medianly, longitudinally carinate; (10) tarsi three-segmented, 

 small, euplectine, with last tarsomere bearing a large claw.
