the Gardeners' Chronicle for May 16, 1908, p. 313, by Mr. F. 

 Denis, will enable one to identify this species. 



Tcnthccoris bicolor Scott 1886, synonym Euritotarsus orchidcarum 

 Renter 1902. 



Head, pronotum and external edge of upper wings of a pronounced 

 brick red color; thorax and rest of upper wings, bright blue; antennae 

 and legs, yellow ; upper side of body and antennae covered with fine 

 short hairs ; head conical in front with well developed eyes ; antennae 

 more than half as long as the body. Pronotum constricted, with a 

 deep ridge in the centre of the constriction. The under part of the 

 body is of a reddish-yellow. The length excluding antennae, 4 mm., 

 the breadth rather less than 2 mm. 



Castnia therapon Koll. (Lep.). 



This is a rare insect in orchid houses occurring only in a 

 very limited way. The large, pinkish white larva of this 

 species bores through the rhizome and up into the bulb, doing, 

 of course, considerable damage. Oncidhnn crispum, Cattleya 

 labiata and Catasctum spp. are the recorded food plants. 

 Brief mention is made of this species together with a figure 

 of the adult in Seitz's Macrolepidoptcra of the World, vol. VI, 

 p. 12, plate 7, a, which gives Brazil as its native home. It is 

 undoubtedly imported every year or so in orchids from Brazil 

 and never becomes permanently established in the orchid 

 house, as the adult is too large and showy to escape attention. 



ParalleloJiplosis cattleyae Moll. (Dip.). 



This species known as the Cattleya midge is another rather 

 rare insect. The larval stages are passed as yellowish-white 

 maggots near the tips of the roots resulting in unsightly swell- 

 ings, which disfigure the roots and check growth, sometimes 

 causing them to turn black and die. According to Dr. E. P. 

 Felt, who gives a brief account of this species in the N. Y . 

 State Museum Bulletin 180, p. 89, each gall may contain from 

 one to seven maggots, each in a cavity by itself. Orchids im- 

 ported from Guatemala often have the roots badly disfigured 

 by these swellings. (Plate IV, fig. i). 



Eucactophagus graphipterus Champ. (Col.). (Plate V, fig. i.) 



This interesting and large member of the family Cctlandri- 

 dae is a native of Costa Rica and the U. S. of Colombia. It
