Tune, I9II-] Schaeffer: New Coleoptera. 123 



have seen, including three specimens kindly sent me by Mr. Fall for 

 comparison, are very variable, some specimens have black elytra with 

 pale lateral spot, others have apex and part of suture ferruginous 

 and sometimes the base also ; one specimen has an elongate ferrugi- 

 nous subapical heart-shaped sutural spot, the pale lateral spot is also 

 very variable in size. 



In one male kindly sent me by Mr. Fall the elytra shows very 

 plainly near suture two longer impressed stride and one shorter, and 

 the black triangular lateral spots of the abdomen extend almost across 

 the base of each segment, other specimens show a faint indication of 

 one or two striae near suture. In two specimens of pallipcs there is 

 also a faint indication of two or three striae near suture. Wolcott 

 described substriafa and separated it from the rest of the species on 

 the possession of two or three striae near suture and the dark abdomen. 

 As shown above, this occurs in caUfornica also and if there are no 

 other characters to separate the tw^o substriata has to be united with 

 califoniica. 



Substriata Wolc. is not included in the following table, as I could 

 not find in the description a good character to include it in the fol- 

 lowing table :^ 



Table of the Species of Monophylla. 



1. Elytra black, granulate rugose, the punctuation nearly obliterated and only 



visible at basal third ; prothorax unicolorous red, punctuation coarse and 

 dense at apical margin, fine and very sparse at middle of disk ; last an- 

 tenna! joint of female about as long as the four preceding joints. 



ruficollis n. sp. 

 Elytra distinctly punctate from base to apex 2 



2. Antennae of female ten-jointed 3 



Antennae of female nine-jointed 4 



3. Prothorax black, elytra brownish with a more or less distinct transverse 



pale spot at middle of lateral margin ; femora black, tibiae generally pale ; 



' Through the kindness of Prof. Wickham I received the type of AI. sub- 

 striata Wolc. in time to add a note on the species. 



M. substriata Wolc. is, as I suspected, the same as califoniica Fall. The 

 thorax in substriata is not densely but sparsely punctate and much less rugose 

 than in the five specimens of caUfornica before me, but these, however, show 

 enough variation in this respect to indicate that the two cannot be separated 

 on the sculpture of thorax. The abdomen in Wolcott's type is a little com- 

 pressed, but the black or piceous spots at sides can be plainly seen. The sub- 

 sutural striae are said to be punctate-striate, which is not the case, they are 

 feebly impressed and cannot be seen in certain light.
