Roslindale, but as yet has not been reported from the Connecticut Valley. It 

 is said that the chalcidid parasite Tetrastichus asparagi, which deposits its 

 eggs in the eggs of the common asparagus beetle, has 2 and probably 3 broods 

 a year, corresponding to those of the asparagus beetle, and that, judging from 

 its work during the summer under report, it promises to be quite effective in 

 controlling this pest. 



Seventh annual report of the state entoniologist of Montana, R. A. Cooley 

 (Montana Sta. Bui. 79, j)p. 52-58). — In addition to a financial statement and 

 other data, brief mention is made of the entomological features of the year. 

 The pests thus mentioned are the green fruit worm (Xylina sp.), tussock moth 

 (Notoloplms antiqua). buffalo tree-hopper, pear-leaf blister-mite, onion maggot, 

 bronze apple-tree borer, and scale on mountain ash (Aspidiotus sp.). 



[Monthly bulletin of the division of zoolog'y], H. A. Surface (Zool. Bui. 

 Penn. Dept. Agr., 7 (1910), Nos. 9, pp. 263-291; 10, pp. 295-322; 11-12, pp. 325- 

 36S, pis. 3). — These numbers contain reports of Pennsylvania orchard inspectors, 

 work In demonstration orchards, bee-keeping, a nursery inspection report, and 

 an index to volume 7. 



Keport of the entomolog'ist [of Trinidad], F. W. Urich (Bui. Dept. Agr. 

 Trinidad, 9 (1910), No. 65, pp. 160-163). — In this report notes are presented on 

 the insects of importance during the year ended March 31, 1910. 



Froghoppers (Tomaspis postica), the giant moth borer (Castnia licus), and 

 the small moth borer (Diatrcea saccharalis) were the chief pests of sugar cane. 

 Others observed during the year were the striped grass looper (Remigia re- 

 panda), the gru-gru beetle (Rynchophorus palmarum), and the small beetle 

 borer (Sphenophorus piceus). 



The cocoa beetle (Stcirastoma depressum) was the most serious pest in cocoa 

 fields. The leaf hopper (Horiola arquata) was the most important of the in- 

 sects affecting the flowers and young pods. Helioihrips rubrocinctus, while sel- 

 dom absent from the cocoa estates, did only occasional damage. 



In an investigation of complaints received that beetles were attacking and 

 destroying coconut palms, it was found that " in dead or dying palms still 

 standing, larvje of the bearded weevil (Rhina barbirostris) were plentiful and 

 trees that had been recently felled attracted large numbers of the gru-gru beetle 

 (R. palmarum). At Mayaro a species of Sphenophorus was found attacking a 

 tree that was affected by root disease. Xyleborus perforans was also found on 

 diseased palms. In the Cedros district the adult of a rhiuocerus beetle (Oryctes 

 sp.) destroyed young coconut plants by burrowing into them from beneath and 

 damaging the internal soft tissues." Three species of scale insects, Vinsonia 

 stellifera, Aspidiotus destructor, and Icerya montserratensis were observed in 

 small numbers on coconut palms. 



The young nymphs of the giant locust (Tropidacrls dux) made their appear- 

 ance in one district in swarms at the opening of the rainy season ; it was de- 

 termined that their nymphal period lasted from May to July. 



Notes on some insect enemies in Tobago, P. L. Guppy (Bui. Dept. Agr. 

 Trinidad, 9 (1910), No. 65, pp. 135-139). — The insects noted include the cotton 

 stainer, tobacco hornworm, tobacco bud worm, castilloa blight due to attacks of 

 the "Akee " fringed scale ( Aster olecanimn pustulans), cocoa thrips, tobacco flea 

 beetle, and mealy bugs. 



Report of superintendent of entomology, E. M. Ehrhorn (Haioaii. Forester 

 and Agr., 7 (1910), No. 11, pp. 336-338) .—The Mediterranean fruit fly Geratitis 

 capitata is reported to have appeared in Hawaii on the Island of Oahu. It is 

 stated that the pest must have been in the islands at least 2 years, if not longer. 

 The mandarin orange, lime, and common seedling orange are reported to be
