HEMIPTERA 367 



(Subfamily Emesidae.) 

 14. Ghilianella galapagensis sp. nov. 



A female. — Body slendei', color brown, abdomen mottled with 

 darker brown. Head nearly thi'ee-fourths the length of prothorax, 

 sparsely granulated, eyes moderate ; the usual porrect fi'ontal spine is 

 reduced to a blunt tooth. Antennaj light brown, first and second 

 joints equal ; the terminal joints are wanting in the specimen. Front 

 legs ochraceous, comparatively short and stout, the large spine near 

 base of femora tipped with black ; tibiae faintly annulated with brown, 

 front tarsi claw-like, equal in length with the tibiae ; femora of the 

 middle legs about as long as abdomen, but the femora of the hind 

 legs longer; the tibiae annulated, at base pale orchraceous. Meso- 

 thorax and metathorax equal in length ; prothorax a little longer and 

 ornamented with two oval-shaped spots, and a longitudinal line in the 

 middle, pale ochraceous, also a streak on the sides near apex; above 

 densely covered with small brown granules, less so below. Meso- 

 thorax and metathorax have a flat surface, the sides obsoletely granu- 

 lated and sharply edged, and a longitudinal, raised line in the middle ; 

 a well defined carina on the underside of the body runs from the base 

 of mesosternum down to the apex of sixth segment of abdomen. 

 The abdomen is gradually inflated from the end of second segment to 

 the fifth and then narrowing slightly towards apex ; the lateral mar- 

 gins are a little raised, more so on the last segments ; the first genital 

 segment is slightly sloping, and the apex rounded off, the second 

 abruptly declivous ; dorsal part of abdomen flat, imder side much 

 rounded ; first and second segments, seen from above, equally long ; 

 the third, fourth and fifth gradually become shorter, the sixth segment 

 is shortest ; at sides of second segment a little behind its base are two 

 small erect spines, also small tubercles at apex in the middle of nearly 

 all the segments, the one on the fourth segment is more prominent. 

 The under side of abdomen is beset with small, stiff, golden hairs, 

 which are irregularly arranged. Length 13 mm. 



Type. — No. 4931, U. S. Nat. Mus. 



One specimen, collected on Hood Island, May 8, 1S99, and one 

 larva collected on Albemarle Island, March 15, 1S99. This insect 

 seems so distinct from the other species of the genus, that I have ven- 

 tured to describe a new species from but one specimen. It somewhat 

 resembles G. gibbiventris Champ, and also G. Jiliventris Spin., but 

 differs from both in length of meso- and metathorax, which are 

 equally long, and in the structure of the abdominal segments. The
