 Length 4J mm. 



Hah. Guatemala, near the city, 5000 ft. {Salvin). 



One specimen, found placed under Belotus abdmninalis 

 in the " Biologia " collection. Smaller and less elongate 

 than /. dichelifer, $, the fuscous portion of the elytra 

 extending outwards to the humeri, the subconical pro- 

 cesses of the last dorsal segment much shorter. Three 

 smaller immature females with the prothorax wholly 

 flavous, from Capetillo and Duenas, must also belong to 

 the same species. Allied S. American unnamed forms are 

 contained in the Fry collection at the British Museum.

Three females seen, two of which were found placed as a

 These have the head and prothorax reddish or rufo-piceous 

 and paler than the elytra, the apical margin of the latter 

 being yellowish in one of them, and the tibiae more or less 

 infuscate in their outer half; the upper surface closely, 

 very minutely punctate ; and the produced lateral portions 

 of the terminal dorsal segment of the abdomen triangular, 

 much as in the same sex of /. {Lobetus) mirabilis, Gorh.
