The part of the label (Det. by - -) as it is uniform 



throughout is written on the typewriter. The scientific names, 

 however, are so variable in size that they must be printed in 

 ' by hand with india ink. Two spaces are left between the labels 

 and at least four spaces between the rows of labels. When 

 the sheet is rilled with labels it is placed on a drawing board 

 and two lines one-eighth inch apart drawn between the labels 

 both horizontally and vertically with india ink. This facilitates 

 the cutting out of the labels when they are finished and the 

 black around the border adds to the neatness of their appear- 

 ance. When the names of the insects have been printed in the 

 rectangular spaces made by the ruling, the sheet is ready to be 

 photographed. 



Duplicate specimens of the same species are taken care of 

 very nicely. An estimate is made of the number of prints to 

 be made from the sheet in question and the number of dupli- 

 cate labels will be governed accordingly. For example, if there 

 are a hundred specimens of one species and twenty of another 

 and the negative is to be printed twenty times, five labels 

 would be made of the one species and but one of the other. 

 The number of prints made from one label sheet will neces- 

 sarily depend upon individual cases. 



Thr best photographic results have been obtained with 

 Cramer's Contrast Plates developed by the formula enclosed 

 with the plates. Contrast Cyko No. 6 is used in printing. 



It is needless to add that the labels must be very thoroughly 

 fixed and washed in order to insure permanency. 



Tenthecoris bicolor Scott, in New Jersey Greenhouses (Hemip.). 

 This blue and red memher of the family Miridac is occasionally 

 met with in New Jersey greenhouses where orchids are grown and 

 has been taken at various times by inspectors examining orchids 

 from South America. Tt is a common occurrence to find the leaves 

 of Cattleya orchids imported from Brazil sometimes covered with 

 irregular white spots due to the abstraction of chlorophyll by these 

 bugs. As a rule, it is never abundant enough in New Jersey" green- 

 houses to do much damage, although it has been known in the past 

 to occur in numbers sufficient to seriously weaken and disfigure the 

 orchids. It is incorrectly known to many orchid growers as tin- 

 Hra/ilian thrips. Additional notes on this species and its introduc- 

 tion into England can be found in the C, a rdc tiers' Chronicle for M.i\ 

 16, 1908. HARRY B. WEISS, New Brunswick, New Jersey.
