162 ENTOMOLOGICAL NEWS [xxxii, '21 



The rain hampered collecting mainly by making it almost 

 impossible to beat the vegetation. A water-soaked net cannoc 

 be properly handled, and the drenched foliage prevents main 

 specimens from falling into the net. On the other hand many 

 individuals could be located even during showers and, as soon 

 as the rain stopped, insect life appeared on all sides in favorable 

 situations. 



Night work proved on the whole disappointing, due appar- 

 ently in large part to the fact that few species could be heard 

 stridulating. Such work would probably have proven more 

 profitable later, when adults, particularly of the species of Tet- 

 tigoniidae, would be present in much larger numbers. The 

 Blattidae are nocturnal and many species missed in searching 

 their retreats during the day may be secured at night. Such 

 was true in the case of Euhypnorna grata here described, the 

 only specimen of which was easily secured at night, being found 

 resting on the upper surface of a green leaf on the edge of a 

 heavy tangle of vegetation. 



Only in areas of heavy tangled vegetation, growing on 

 low wet ground, was material found abundantly. Collecting 

 on higher ground proved very unproductive, both in brushy 

 and forested areas, while over extensive pasture lands the only 

 material of interest was taken from under the dead bark of 

 decaying logs. 



The localities visited were Paris Field on July 7 and August 

 18 (referred to below as P7 and P18 respectively), and Gatun 

 on July 8 (referred to below as G). 



Adding the additional genus and three species here recorded, 

 which were hitherto unknown from Panama, the total number 

 of Blattidae recorded from this region is now fifty-four genera 

 and one hundred and six specie.-. The rich character of the 

 region is better understood when we realize that but forty-nine 

 species and races of the Blattidae are known from all of North 

 America north of the Mexican boundary. 



Lissoblatta fiilgida (Saussure). Pi, 2 $. Both of these males are 

 very dark and immaculate in coloration. Very few specimens 

 were found. 



Anaplecta cabimae Hebard. P7, 2$; G, 1 9. A very few speci- 

 mens were seen at Paris Field; these were found at night on the 

 leaves of a twenty-foot high reed or grass.
