Hbn., was observed on Virginia creeper ; a sawfly, Dipriun abietis, 

 Harr., on balsam fir ; and twig-borers, Oberea tripunctata, Swed., on 

 dogwood, and 0. trijpunctata var. myops, Hald., on azalea and 

 Oxydendrmn. Agrilus sinuatus, Oliv. (sinuate pear borer) was recorded 

 for the first time from Connecticut ; no remedy is known for this 

 pest other than destroying infested trees. Harrisina americana, 

 Harr., was found on Virginia creeper ; the Psocid, Pterodela pediciilaris, 

 L., occurred in wheat middlings, heat being recommended for deahng 

 with this pest ; grubs of Tyloderma foveolatnm, Say, tunnelling in 

 stems of evening prunrose ; and larvae of Chelymorpha argns, Licht. , 

 on peas and wild morning glory. 



The elm leaf beetle [Galerucella luteola] increased rapidly during the 

 year and gave every indication of again appearing in devastating 

 numbers. Residents in towTis where the beetle has been numerous 

 are asked to be on the watch and to spray the trees with lead arsenate 

 as soon as the insects appear. One thorough application about 

 1st Jime will generally protect the foliage for the season. Malacosoma 

 neustria, L. , was intercepted from Holland in a shipment of Mains and 

 other plants. Malacosoma americana, V., after a period of abundance 

 lasting for two or three years has now practically disappeared from 

 Connecticut. Larvae of Marmara (Gracilaria) elotella, Busck, the life- 

 history of which has recently been studied [see this Review, Ser. A, vi, 

 p. 21], have been found mining in apple twigs, but apparently very 

 little damage is done by them. Olethreutes hemidesma, Zell., was 

 found on terminal shoots of Spiraea ; if this moth should become 

 very numerous a lead arsenate spray should be applied during 

 July; clipping ofE and burning infested shoots is also advisable. 

 Pissodes approximatus, Hopk., is an injurious weevil attacking red 

 pine. Apparently only an occasional tree is attacked ; the only 

 measure that can be recommended is to destroy infested trees. 

 Contarinia tritici, Kirby (wheat midge) has been found injuring rye, 

 the larvae eating out the kernels in the hull. There is probably one 

 brood in each year, though in certain seasons in some parts of the 

 country there may be a partial second brood. Burning the stubble 

 has been recommended as a remedial measure, followed by deep 

 autumn ploughing and rotation of crops. Grasshoppers and crickets 

 were unusually abimdant during the season, and did considerable 

 damage by eating the second crop of grass in many fields. The usual 

 poisoned bran mash is recommended for their destruction.

Measures against these two pests have been continued on the same 

 lines as in preceding years [see this Review, Ser. A, v, p. 307]. The 

 brown-tail moth [Nygmia phaeorrhoea] has not spread appreciably 

 during the last two years ; the clipping off and destroying of the winter 

 nests has been continued, and very few webs have been observed. The 

 gipsy moth [Lymantria dispar] has been numerous in the north-eastern 

 counties. Every effort was made to visit all of the infested localities 

 during the caterpillar season, and over 37,000 larvae were killed.
