238 PHYTOPHAGA. 



29. Leptitiotarsa flavopustulata. (Tab. XIII. fig. 17.) 



Calligrapha fiavopustulata, Stfil, Diagn. 1860, p. 460; Monogr. Chrys. Amer. p. 169 \ 

 Hob. Guatemala \ San Juan in Vera Cruz, Chacoj (Champion). 



The type of this species, contained in the collection of Mr. Baly, was originally 

 placed by St&l in the genus Calligrapha ; the distinctly channelled tibia?, however, 

 make it advisable to transfer the insect to the present genus, where it is also put in 

 Gemminger's catalogue. Two other specimens have been obtained by Mr. Champion, 

 which vary from the type in being of a, dark fulvous colour, with the exception of the 

 elytral spots, which are the same. One of these is figured, which makes a detailed 

 description of the spots unnecessary. 



30. Leptinotarsa belti. (Tab. xill. fig. 18.) 



Stilodes belti, Jacoby, P. Z. S. 1879, p. 782. 



Hob. Guatemala, Chacoj, Panima (Champion) ; Nicaragua, Chontales (Belt). 



For the same reason, having the tibia? sulcate, this species had better find its place 

 here. In structural characters it is identical in every respect with the preceding 

 species ; and in spite of the totally different design of its elytra, which is the same in 

 the four specimens before me, I cannot help feeling some doubt as to whether they are 

 not merely varieties of L. flavopustulata. It is true that no sign of any flavous spots 

 exists here; if, however, the dark markings surrounding those of L. flavopustulata were 

 interrupted in a certain way, a design like that found in the present species would 

 be the result. At present, however, in the absence of intermediate marked specimens, 

 I cannot but consider the species a distinct one. 



31. Leptinotarsa evanescens. (Tab. XV. fig. 2.) 



Calligrapha evanescens, Stfil, Diagn. 1860, p. 460. 

 Chrysomela evanescens, Stal, Monogr. Chrys. Amer. p. 168 \ 



Hob. Guatemala x ; Costa Rica x . 



Of this species I have seen only Stal's type, in the collection of Mr. Baly, and which 

 is figured. The insect has not been met with by Mr. Champion or Mr. Rogers, and is 

 no doubt rare. The thorax is crowded with smaller and larger punctures, the latter 

 being specially numerous near the sides. The elytra also are very strongly and closely 

 punctate near the sides, geminate punctate-striate near the suture. For their pattern, 

 Stal's description and the figure must be compared. 



32. Leptinotarsa distinguenda. (Calligrapha distinguenda, Tab. XIV. fig. 25.) 

 Calligrapha distinguenda, Jacoby, P. Z. S. 1877, p. 518 . 



Hob. Guatemala, Teleman, Chacoj (Champion) ; Nicaragua, Chontales 1 (Janson).
