CACTUS-FEEDING INSECTS AND MITES 103 



Moneilema crassipes Fisher 



Another fairly large, wholly black form known from one locality 

 only, M. crassipes was described from material collected in August 

 and September 1930, in a valley lying between Miquihuana in the 

 southern corner of the State of Nuevo Leon and Palmillas in the 

 adjacent territory of the State of Tamaulipas, Mexico. The beetles 

 were not uncommon and were again taken in the same area in June 

 1931. 



Moneilema opuntiae Fisher 



A rather small, black, almost-smooth insect, M. optuniae was described 

 from a few specimens collected at San Luis Potosf, Mexico, in May 

 and June 1927. There are no other records of its occurrence. 



Moneilema vittata Fisher 



A medium-sized black species, M. vittata has a broad white stripe 

 on the apical half of the elytra. The only specimens were a few collected 

 at Aguascalientes, Mexico, in May 1927. 



Moneilema mexicana Fisher 



This rather small, wholly black insect seems to be another of the rarer 

 forms. A few individuals have been taken in May and June at San 

 Luis Potosf, and in May at Pachuca, State of Hidalgo, Mexico. 



Moneilema ebenina Bates 



A moderate-sized black species, M. ebenina is found in southern Mexico 

 and is not uncommon in the vicinity of Tehuacan. Adults have been 

 collected in March and April at Tehuacan, State of Puebla, in October 

 at Oaxaca, and in the same month at Chilpancingo, State of Guerrero. 



Moneilema punctipennis Fisher 



This form was described from specimens taken at Tehuacan, State 

 of Puebla, Mexico, in April 1926. The adult is medium-sized, wholly 

 black, with rather coarsely punctured elytra contiasting with the 

 smooth prothorax. 



Moneilema mundelli Fisher 



A moderately large species, M. mundelli has distinct irregular white 

 markings on the prothorax and elytra, was described from material 

 collected in eastern Mexico in April 1931. The adults were prevalent
