workers; this was as true in the case of the veriest beginner as 

 with the experienced specialist. Gentleness and consideration of 

 others were his predominant personal qualities and in all respects 

 his character was without blemish. As a systematist great cau- 

 tion, infinite painstaking, and a high degree of artistic ability 

 have made his published work as satisfactory and reliable as any 

 that has been done. W. L. McATEE. 



Leptoypha distinguenda n. sp. 1 (PI. 17, fig. 1). 



Specimens of this new species might, at first sight, he taken for L. mutica 

 Say, hut closer observation shows that it is very different. 



In L. distinguenda the body is broader, the pronotum is less elevated 

 between the humeri, and the lateral carinae are more prominent. The 

 costal margin is distinct along the whole length of the hemelytron, some- 

 what reflexed anteriorly and containing there two series of small areoles. 

 In L. mutica however the costal margin is much narrowed anteriorly, con- 

 tains only a single indistinct series of areoles and is not at all reflexed, 

 posteriorly also it contains a single series of areoles, which are much nar- 

 rower than those on the corresponding part of L. distinguenda. 



This species abounds on witch-hazel (Hamamelis) from early 

 spring to late in fall. 



Type, a female, from Washington, D. C., July 8, 1899. Other 

 specimens are from the same locality June 20, July 28; Rock 

 Creek, D. C., June 20, 1890; Marshall Hall, Md., August 1, 1891, 

 September 3, 1891; Virginia, opposite Washington, D. C., June 

 15, 1902; [all of the foregoing without collector labels, but prob- 

 ably collected by Mr. Heidemannj; Mount Vernon, Va., April 19, 

 1904, R. P. Currie. All in collection of U. S. National Museum. 



Acalypta grisea n. sp. (PI. 17, fig. 2). 



General color light-brown with the areoles grayish subhyaline. This 

 species differs from A. thomsonii Stal. (PI. 17, fig. 3), the only recorded 

 American species, in several particulars, of which the most noticeable is 

 the possession of only a single series of areoles throughout the costal 

 margins of the hemelytra. A. thomsonii has more than one series of 

 areoles anteriorly and in the posterior third to half of costal margin. 



A. grisea belongs to that section of Acalypta having the three pronotal 

 ridges of nearly equal height, subparallel and extending from posterior 

 margin to the transversely elliptical and small but elevated hood. The 

 central ridge does not form so conspicuous a ridge and apex on the hood 

 as it does in A. thomsonii. 



A. thomsonii on the other hand has the lateral ridges very low and the 

 central ridge strong, rising gradually from the point of posterior process 



1 This species may have been distributed to some extent under the ins. 

 name confusa an earlier preference to Mr. Heidemann.
