 not show any structural differences.

Variable in colour above. The typical form has black elytra, the thorax red, with a 

 broad median piceous band, the head and body beneath rufo-ferruginous. Specimens 

 seem to be more abundant of an entirely rufo-castaneous colour. Examples rarely 

 occur like the typical form and with the thorax entirely red.

 Hah. Costa Rica 1 . 



This species resembles some of the forms of L. bicolor ; but the head is black, the 

 meso- and metathorax are piceous-brown, and the abdomen is more reddish-brown. 

 No specimens have been, seen by me. 



10. Lissomus inopinatus. 



Oblong-oval, moderately robust, piceous-black, shining; thorax red, with a broad median piceous band; 

 antennae black, second and third joints brown : head moderately coarsely, not closely punctate, impressed 

 in front ; thorax much wider than long, sides gradually narrowed at the front, feebly arcuate and some- 

 what sinuous, apex not deeply emarginate, surface relatively finely and sparsely punctate ; scutellum 

 smooth ; elytra scarcely gibbous, parallel at the sides, arcuately and rather obtusely narrowed at the 

 apical third only, surface very finely and distantly striate-punctate, submarginal line entire ; body beneath 

 entirely black, except the sides of the prothorax, which are red ; metasternum and abdomen moderately 

 coarsely but not closely punctate ; legs piceous-brown, tarsi paler. 



Length 5-5-8 millim. 



Hab. Nicaeagua, Chontales (Belt) ; Panama, Bugaba, Volcan de Chiriqui, David 



(Champion). 



Like L. bicolor, this species varies from the normal colour to entirely rufo-castaneous. 



It is, however, always shining black beneath, and has the head black. Superficially,
