margin, particularly at the base, reflexed : elytra black-bronzed, less glossy 

 than the head and pro-thorax, lightly furrowed ; furrows punctured ; in the 

 interstice between the second and third furrows are five punctiform impres- 

 sions, two nearer the base and three nearer the apex of the elytrum, so that 

 the interval between the second and third is greater than that between the 

 others. 



Variety B. Second and third punctiform impressions not more distant than 

 the others. In this specimen, on the left hand elytrum, there 

 are only four impressions and on the other five, but in neither 

 are the second and third situated as in A. It may be a dis- 

 tinct species, but I can discover no other difference.

Body glossy, underneath very black, above black slightly bronzed. An- 

 tennae scarcely longer than the prothorax : prothorax rather longer than 

 broad; basilar impressions roundish, impunctured : elytra more bronzed than 

 the head and prothorax, lightly furrowed; furrow adjoining the suture more 

 depressed and deeper than the rest ; in the space between the second and 

 third furrows are five equi-distant punctiform impressions, the two anterior 

 adjoining the latter furrow, and the three posterior the former. 



This little species greatly resembles A. seminitidum. It is however much 

 smaller, less bronzed, the prothorax is longer in proportion, the sutural fur- 

 row is deeper, and the impressions are differently arranged. 



AX INSECT FKIEND. 



Anna placidum, Ulke. 

 The accompanying figure correctly represents the 

 mature form of the friendly bug referred to in the 

 " Canadian Entomologist," Vol. ii. No. 2, which was 

 found feasting so energetically on the larvae of the 

 gooseberry saw fly (Nematus veatricosiis). Fur a des- 

 cription of the appearance and habits of the inmature 

 form of this beneficial insect the reader is referred to 

 the above number of the "Canadian Entomologist." 



The perfect insect has been determined by Mr. Ulke, 

 of Baltimore, Md., who found it to be an undescribed 

 species of Anna, to which he has given the specific name placidum. Hence 

 our friend will in future be known as Anna placidum, Ulke. 



The excellent drawing of the insect is the work of our esteemed and able 

 friend C. V. Riley, Esq., State Entomologist of Missouri, who has kindly
