The new species described include Lasiapter a paniculi, from panicles 

 of Panicum carinatum ; Toxomyia hrideliae, on leaves of Bridelia 

 stipularis ; and Mycodiplosis spondiasi from Spondias momhin. It is 

 uncertain whether the last-named is a gall-making or predaceous 

 midge.

The insects injurious to clover in Colombia include Cantharis 

 erythroscelis. Berg, a native beetle that appears from about November 

 to January and devours the leaves of clover, lucerne, potatoes, etc. 

 It is advisable to cut down and reap as early as possible any infested 

 clover destined for forage, but if it is required for seed, the only remedy 

 is to keep the soil under constant irrigation and cut the crop when 

 required. Lepidopterous larvae, when very numerous, devour the 

 leaves in great quantities ; the best remedy is to take off the crop as 

 lightly as possible, pasturing as many animals as is practicable on the 

 fields. Another method is to mow the clover before it is mature, 

 and a day or two later to pass heavy rollers over the ground, which 

 would kill a large number of the caterpillars. The clover should then 

 be dried and burnt, to destroy the insects in it. One injurious insect 

 [Bruchophagus funebris] has been known in the Republic since 1910, 

 and is sometimes very destructive to clover seed ; fumigation with 

 carbon bisulphide is recommended, after which the seed should be 

 separated by a fanning machine from the dead insects. Bryobia 

 pratensis (red spider) appears in dry summer weather, weaving webs 

 over clover, lucerne, beans, and other plants. These webs should be 

 destroyed with rakes made of thorn branches, and the plants should 

 then be well watered. Poultry are useful in breaking the webs 

 with their feet when allowed to run in the fields.

The National Congress has just voted a sum to be used in an anti- 

 locust campaign when found necessary in Colombia. Although locusts 

 do not seem to occur in the inhabited parts at the present time.
