244 THE CANADIAN ENTOMOLOGIST 



from whom received, general condition, and other details worth 

 recording. The first lot received in the following year bear re- 

 ference label "14-1." This system is in use in many museums, 

 notably at Washington and in British Museum, and has many ad- 

 vantages to commend it. 



The collection contains very few actual types, probably not 

 more than a dozen, and fewer than a hundred co-types. But 

 the next in value to types, and frequently, be it said, of far greater 

 value than co-types, are specimens personally compared with 

 types, co-types, with other important specimens, and with figures 

 and descriptions. These specimens all bear extra explanatory labels, 

 such as "Xd male type* at Rutger's College," with brief indication 

 as to its concise points of dilTerence, or " =beta female type at 

 Brooklyn, exactly," ov'' Alpha delta, agrees with fig. of type," etc., 

 etc. Specimens submitted to experts are similarly labeled, (in 

 red ink) with reference to filed correspondence in corrobcrration. 

 Specimens of which figures have been published are also marked. 

 Some specimens have been compared with two or more types, and 

 synonymic references thereby made or confirmed. 



In addition to the above "authenticity" pin-labels, small 

 card labels are placed at the side of these specimens so that they 

 may be found quickly. These are more brief, and the most im- 

 portant ones are on tinted card, to catch the eye. For instance, 

 a small, red-tinted label beside a specimen in the series of Euxoa 

 catenula Grt., "Xd type, and contagionis Smith Xd type," would 

 indicate the one by comparison of which with both types the re- 

 ference of contagionis to catenula had been made. Varieties are 

 not often separated or indicated as such, but merely by a similar 

 side label bearing the n'ame under which the form was described, 

 whether actually compared or not; e. g., under Monima hibisci 

 {Tceniocampa alia of our lists) would be a large species name- 

 label, "hibisci Gn.," at the foot of each column, and each one 

 bracketed except the last. At the side of one specimen might be 

 a small label " quinquefasciata Sm.," which is considered a varia- 

 tion. In this particular case an "Xd type" or "Xd description" 

 specimen is probably referred to, though a specimen thus indicated 



*The author uses a private symbol cf , enclosed in a circle, to indicate male 

 type, and 9 , enclosed in a circle, for female type.
