SUPPLEMENT TO PSYCHE. 



\r 



pubescence except that the tliird has a 

 broadly triangular black central patch, the 

 apex of which is directed liindwards. Apex 

 rufous. Second segment at sides and ven- 

 trallj strongly punctured, dorsally the surface 

 cannot be seen because of the pubescence. 



Hab. — Gordon Town, Jamaica. CDr. 

 Cargill.) Communicated b_v Mr. L. O. 

 Howard. Type in U. S. Nat. Museum. A 

 very beautiful and distinct species. 



Chrysididae. 



Holopyga semirufa, n. sp. — Length about 

 or slightly over 3 mm. ; liead and thorax 

 bright green, occiput and metathorax deep 

 purple. Antennae very dark brown, the 

 scape green. Pro- and meso-thorax shining 

 slightly reddish brassy in some lights. 

 Metathorax with a very little green mid- 



dorsally. Wings clear, nervures riark brown. 

 Abdomen modcrateh' shining, entirely ru- 

 fous. Legs rufous, anterior and middle 

 femora and tibiae darker, anterior femora 

 green except the end. 



Whole insect strongly punctured, the 

 punctures finer on the abdomen. Third 

 segment of abdomen entire. Claw with two 

 teeth within. Marginal cell open at apex; 

 no discoidal cells, the outline of the second 

 is very faintlv and imperfectly indicated. 

 Metathorax with a strong spine on each 

 side. Hind ocelli about as far from one 

 another as each froin orbital margin. 



Hab. — Las Cruces, N. ^L, close to the 

 Agricultural College, Sept. 11, 1S95, on 

 Bigelovia wrig/iiii. Recognized at once by 

 its rufous abdomen and legs. The type is 

 Ckll. 5012. 



IX. A Cerdpi^astes and its Parasite. 



Ceroplastes euphorbiae, n. sp. — J scale 

 3i njm. long, 3 broad, 2^ high. Wax white, 

 rather thick, firm, not divided into plates. 

 The plate-nuclei or knobs, however, are 

 very distinct, each on a small dark pink 

 patch. Obscure bands of« white secretion 

 descend from the lateral ones. Denuded, 

 the 9 shows a well-formed caudal horn, 

 about the shape of the last joint of one's 

 little finger, but rather more tapering. The 

 material being rather insufficient, the micro- 

 scopic characters were not very well made 

 out. The antennae appear to be only 

 6-jointed. but it is the fourth joint, not the 

 third, that is much the longest. The second 

 and third are next longest and subequal, 

 the second perhaps a little the longer. The 

 fifth is quite short. Derm with round gland- 

 pits. Legs ordinary, femur a little longer 

 than tibia, tibia longer than tarsus. Digi- 

 tules with large knobs. A detached leg 

 exhibited a prodigiously long tarsal digitule, 

 at least twice as long as the tarsus itself 



Half grown examples have the wax di- 

 vided into plates, but the sutures are not 



darkened. Quite young ones are pink with 

 all the knobs conspicuously white. 



//<;/'.— Red Hill District, Jamaica, Oct. 

 28, 1S95, on the twigs or branches of 

 Enp/iorbia liyfericifolia L., sent by Dr. 

 M. Grabham. 



This little species has some resemblance 

 to C. iheiingi Ckll., but will be known 

 by its white wax, with the knobs on dark 

 pink patches. From C. floridensis Comst., 

 it will be known by its higher form, and 

 the dark knobs of the adult, situated on 

 dark pink patches. From C. euphorbiae 

 I bred a parasite, which Mr. L. O. Howard 

 describes as a new genus and species of 

 Aphelinine Chalcididae. His description 

 follows. T. D. A. Ckll. 



Aneristus, n. gen. — Resembles Coccopha- 

 gus. Flagellum of antenna strongly flat- 

 tened. Scape short, inserted just above 

 the mouth and reaching to the middle of 

 the face ; pedicel short, triangular, as long 

 as broad. Funicle joint i twice as long as 

 pedicel, somewhat longer than broad.
