EPISTENIA. 



Epistenia, Westwood, in Griffith's Animal Kingdom, Ins. ii. p. 432, t. 77. 



A widely distributed genus over the warmer regions of the globe. Lycisca, Spinola r 

 does not apparently differ to any great extent from it. 



1. Epistenia balteata. (Tab. VI. fig. 3, $ ; 3 a, labium and labial palpi ; 



mandible.) 



Cyaneo-viridis, nigro et purpureo maculata; pedibus rufis, coxis subtus femoribusque posterioribus subtu& 



viridibus ; antennis nigris, scapo viridi ; alis hyalinis, fusco maculatis. 

 Long. 16-18 millim., Cauda 5-6 millim., g 12 millim. 



Hob. Guatemala, San Ger6nimo, Teleman, Panzos and El Eeposo 800 feet

Antennae not much longer than the thorax; flagellum thick, becoming gradually 

 thicker towards the apex ; second joint scarcely shorter than the third, thinner than 

 the latter, especially at the base, where it is more or less green ; the following joints 

 are much shorter, the fourth is a little longer than the fifth, the last is one half longer 

 than the preceding. Head as broad as the thorax; face coarsely punctured; the 

 vertex and the posterior region less strongly punctured; the antennal depression 

 smooth, shining, impunctate. Face covered with a short, thick, white pubescence ; 

 vertex with shorter black pubescence. Thorax coarsely rugose ; the pleurse and breast 

 less strongly punctured. Scutellum rounded and projecting behind, and with a distinct 

 margin. Four basal segments of abdomen finely punctured; cauda as long as the 

 three preceding segments, pilose. Coxae punctured at the sides and beneath; the 

 posterior pair with a broad depression at the side, the depression usually reddish or 

 purplish in colour. The pronotum in the middle, the greater part of the mesonotum, the 

 abdominal segments at the apex, and the cauda are more or less black or purplish black. 

 The posterior femora either green or purplish beneath, and the tibiae red, or more 

 or less purplish. The wings are short, not much longer than the head, thorax, and 

 basal segment of abdomen; at the base of the ulna, and touching the costa, is a 

 fuscous mark, which is a little broader than long ; at the termination of the cubitus there 

 is a narrow curved fuscous line, which is continued nearly to the apex of the wing ; at the 

 lower part of the wing, opposite the ulna, is a fuscous cloud, narrow and long in shape. 



The male has the legs purple, through which the red appears in scattered small 

 spots; on the inner side of the anterior femora are two irregular white spots. The 

 coloration of the rest of the body in the male is pretty much as in the female ; the 

 marks on the fore wings are longer than in the female.
