good points, but the majority are worthless. In fact, rather than put 

 faith in half of those which have been published it were better to rely 

 on the recipe which T. A. Janvier gives in his charming article on 

 "Mexican Superstitions and Folk-lore," published in a recent number 

 of Scribner's Magazine (March, 1889, Vol. Y, No. 3, p. 350), as current 

 amoug the Mexicans: 



To get rid of cockroaches — Catch three and put them in a bottle, and so carry 

 them to where two roads cross. Here hold the bottle upside down, and as they fall 

 out repeat aloud three credos. Then all the cockroaches in the house from which 

 these three came will go away ! 



TWO SPIDER-EGG PARASITES. 

 By L. O. Howard. 



Fig. 58.— A coloides saitidis Howard; female, showing wing veins — greatly enlarged ; male antennae 

 and thorax from side— still more enlarged (original). 



Following up the notes published from time to time in these pages on 

 the subject of the hymenopterous parasites of spiders, I present below 

 a description of two interesting new Proctotrupids of the subfamily 

 ScelioninaB, the first of which was reared by Mr. L. Bruner at Lincoln* 

 Nebr., from the eggs of the Araneid tiaitis pnlex. The eggs of this 

 spider are a little more than a millimeter in circumference, and each 

 egg harbors but one parasite, which issues by splitting the egg open 

 rather than by gnawing a regular hole. 



ACOLOIDES* n. g. (Scelionince). 



Female antennae with very large non-jointed club, and 4-jointed funicle. Male 

 antennae 12-jointed, submoniliforui ; club small, separable into three joints. Mandi- 

 bles 3-dentate. Eyes hairy. Lateral ocelli situated on the eye margin. Mesoscutum 



* Aeolus + eiSos.
