LONGITABSTJS. 373 



numerous, and principally found in Europe, but nearly all other parts of the world have 

 contributed to their numbers; the tropics have furnished but few as yet, and even 

 Central America seems to possess but a small number. 



1. Longitarsus subcinctus. 



Longitarsus subcinctus, Harold, Coleopt. Hefte, xv. 1876, p. 30 \ 



Hab. Mexico, Teapa, Cordova (SalU) ; Guatemala, Cerro Zunil, Teleman, Senahu 

 (Champion); Panama, Volcan de Chiriqui, Bugaba (Champion). — Colombia 1 . 



I have not much doubt that the rather numerous specimens from the above localities 

 should be referred to Von Harold's species, since they entirely agree with the description, 

 and also with a specimen from Colombia contained in Mr. Baly's collection. In most 

 of the specimens a transverse piceous band (as the description gives it) is visible at the 

 sides of the elytra, although rather before than at the middle ; the sides of the thorax 

 are also similarly coloured in many specimens; slight variations in size and other 

 respects are also present amongst the insects from different localities, but not of 

 sufficient importance for the establishment of another species. L. subcinctus is more 

 or less chestnut-brown in colour, and with long and slender antennae, the fifth to the 

 eighth joints of which are generally piceous or black; the thorax is impunctate, and 

 the elytra are very finely punctured. 



2. Longitarsus chontalensis. 



Fulvous ; four basal and the two apical joints of the antennae flavo-testaceous ; thorax extremely minutely, 



elytra more distinctly, punctured. 

 Length \ line. 

 Head impunctate, with a fine oblique groove near the inner margin of the eyes ; antennae two thirds the length 



of the body, the second, third, and fourth joints short and equal, the basal joint stained with piceous 



above. 



Hab. Nicakagua, Chontales (Janson). 



The single specimen before me greatly resembles at first sight L. subcinctus, with 

 which it agrees in the colour of the upper surface and in that of the antennae, but the 

 smaller size by one half of L. chontalensis, and the more distinctly and evenly punctured 

 elytra will help to distinguish it ; the comparative length of the second and the two 

 following joints of the antennae [these joints being much shorter than in the allied 

 pecies] is another distinguishing character of the present insect. 



3. Longitarsus angusticollis. 



Ovate, testaceous or obscure fulvo-piceous ; wingless ; antennae as long as the body ; thorax punctured poste- 

 riorly ; elytra without prominent shoulders, closely, distinctly, and somewhat rugosely punctate. 

 Length \ line. 



Hab. Panama, Volcan de Chiriqui (Champion).
