(43) Viola (ViolacefP). — In March, 1893, Mr. Nuttall brought me a loaf of white 

 violet from Halfway Tree, with DacUjlopms virgaius infesting the under side at the 

 base. The specimens were very strongly banded. 



(44) Ci/cas media (Cycadace:e.) — Plants in Castleton Gardens (Campbell) were badly 

 infested by Biaspis lanatits Ckll. 



(45) Argyreia speciosa (Convolvulace,T). — A plant in Dr. Strachan's garden in 

 Kingston had Diaspis iantatus in abundance on the stem. 



(46) Pehtrgonium vGeraniace.-e.) — A plant at Cinchona (Harris) was badly infested 

 by Diaspis huHitus. I at tirst supposed these scales to represent a species distinct 

 from lanatus, but have quite abandoned this view on further study. 



(30c) HiiiscHs (Abehnoschus) esculentus. — Plants in Castleton Gardens (Campbell) 

 were badly infested by Diaspis lanatus. At first I also thought this was a distinct 

 species, but am now persuaded that it is only lanatus, 



(47) Solanum tuberosum (Solanaceje. — On a potato stem from Farm House, Pedro 

 (J. Richard Reece), I found a $ of Orthezia insignis with several young. 



(48) Mentha (Labiatse.) — On a garden mint gathered in Kingston by Mr. Hall were 

 many Orthezia insignis, and also a few very young specimens of some Lecanium or 

 Pulvinaria. 



(49) Verbena (Verbenacea"). — Mr. Nuttall tells me that at Halfway Tree he finds 

 Orthezia insignis infesting Verbena. 



(50) Mi/osotis ( Boraginacene. ) — I learn from Mr. Nuttall that Orthezia insignis also in- 

 fested Myosotis at Halfway Tree. 



(21b) Punica granatum L. — In the garden of the Museum, Kingston, I find several 

 Ceroplastes floridensis on leaves of Pomegranate. 



(17d) Manglfera indica L, — In Kingston, January, 1893, I found Ceroplastes flori- 

 densis on leaves of Mango. 



OBSERVATIONS ON SOME HYMENOPTEROUS PARASITES OF COLE- 



OPTERA. 



By F. H. Chittenden. 



The following notes are the result of personal observations made by 

 the writer mainly before becoming connected with Government work 

 at Washington, and are supplementary to the records, by Prof. Riley 

 and others, as published from time to time in previous volumes of In- 

 sect Life. 



ichneumonid^. 



Ephialtes irritator Fabr. was reared from its larvte found living ex- 

 ternally on the larvfe of the Cerambycid, Liopus variegatus Hald., 

 breeding under the bark of the Box-elder, Negundo aceroides {Acer 

 negnndo). Larva^ were found in the vicinity of Washington, D. C, 

 May 24. Within four days thereafter they had spun their cocoons, 

 grouping them together with two old empty cocoons of the previous 

 year's brood. These cocoons were at first white, but in a few days 

 slowly began assuming a darker brown hue. June 2 the first pupa 

 was found, and June 5 the first imago, a female, appeared, and in a day 

 or two had liberated herself by gnawing through the cocoon. This 

 insect has been previously bred from an unknown Cerambycid under
