in the death of the host. Infestation probably takes place through 

 the skin, because infested larvae bear small scars in the form of black 

 spots. 



This Nematode, which is here described under the name Aprocto- 

 nema entomophagum, gen. et sp. n., differs greatly from other species 

 and can be grouped only with aberrant forms such as Mermis, Allacto- 

 nema, Bmdynema, Atractonema, and Sphaeruhria, all of which are 

 parasites in insects. 



LouNSBURY (C. P.). Division of Entomology : Annual Report 1915- \/ 



19iQ.—Rept. Union S. Africa Dept. Agric. for Year ended 

 31st March 1916, Capetown, 1917, pp. 83-103. [Received 12th 

 October 1917.] 



A report for the year ending 31st March 1915 was prepared, but 

 was not published ; certain data from that report are included in the 

 present one for purj)oses of future reference. 



Nursery inspection has continued during the year under review, 

 and to those insects already recorded as rendering premises liable to 

 quarantine [see this Review, Ser. A, iii, p. 502] the following scale- 

 insects have been added : Aspidiotus perniciosus, A. africanus, 

 Clirysomplialus {A.) dictyospermi, Lepidosaphes gloveri, Aulacaspis 

 pentagona, Parlatoria pergandei, Pseudococcus aurilanatus and Astero- 

 lecanium variolomm. Regulations governing the introduction of plants 

 and fruits from overseas remain as in the report referred to above, 

 except that the introduction of persimmon stocks has been prohibited 

 and notice is given that, from 1st October 1916, the introduction of 

 apple stocks has ceased. The customary precautions with regard to 

 imported plants, including fumigation or immersion in copper sulphate 

 solution, were carried out with the result that no insects or diseases 

 of any importance were introduced during the year. 



The codling moth [Cydia pomoneUa] continues to spread in spite 

 of stringent precautions. The sending of apples, pears and quinces 

 into certain defined areas is prohibited, the attention of the public 

 being drawn to this prohibition by large posters displayed at railway 

 stations. The removal of plants is also governed by regulations and 

 restrictions for the purpose of checking the dissemination of pests, 

 particularly of Aspidiotus perniciosus. Any new sugar-cane cuttings 

 introduced are kept in quarantine for a time and are only removed 

 subject to departmental approval. 



Migratory locusts were more numerous in the country in 1915-1916 

 than in any previous year since 1909-1910, the species concerned 

 being the bro\\'n locust, Locusta pardalina [see this Review, Ser. A, 

 iii, p. 719]. The law requires that occupiers of land shall report egg- 

 laying and' the appearance of hoppers and that they shall destroy 

 the hoppers, the Government providing the means of destruction. 

 In his 1914-1915 report the author expressed the opinion that a new 

 cvcle of locust years had begim. During 1913-1914 an outbreak 

 occurred in one district of the Cape Province and this was evidently the 

 beginning of the cycle. Early in 1915, apparently quite independently 

 of that outbreak, small swarms and numerous solitary locusts were 

 observed in the south-west of the Orange Free State, and it was from 

 this source that the rather severe outbreak of 1915 developed. The
