PSYCHE. 



[April 1898. 



lected in the State of Vera Cruz, 

 Mexico, by Rev. H. Th. Heyde. This 

 is one of many interesting things which 

 Mr. Heyde has turned up in Mexico, 

 and I take pleasuie in dedicating it to 

 liim. It is nearest constricta and 4- 

 notata, but differs from either in the 

 structure of face and genitals. 



Agallia mexicana n. sp. 



More slender than constricta which it 

 resembles. Length, female 3.5, male 3.25 

 mm. 



Face about a twentieth longer than wide. 

 Front proportioned as in heydei, strongly 

 constricted below the antennae. Vertex as 

 long at middle as at eyes. Pronotal width 

 once and nine tenths the length, the length 

 three and a half times that of the vertex. 

 Elytra proportionally narrower than in 

 constricta. Last ventral segment with hind 

 margin slightly concave, its disc entirely 

 lacking the characteristic depressed areas 

 of constricta. 



Color as in the paler form of constricta, 

 except that tlie spots on vertex and pronotum 

 are much larger, and the elytra are clearer 

 gray. 



Male : Valves narrowing to a slender but 

 obtuse tip, the sides at about half their 

 length more or less distinctly very obtusely 

 angulated. 



Described from many specimens col- 

 lected in the State of Vera Cruz, Mex- 

 ico by Rev. H. Th. Heyde. This 

 belongs to the 4-notata group, which 

 includes 4-notaia, constricta and key- 

 dei. Of this it is nearest constricta, 

 but differs as described above. 



Agallia anomala n. sp. 



Form of novella but smaller. Length of 

 female, 3.5 mm. Face a twelfth longer than 



wide. Front long and narrow, sides evenly 

 curved. Vertex shorter at middle than at 

 eyes, margin back of eyes broad, as in novella. 

 Pronotal width once and three fourths the 

 length, the length about five times that of 

 the vertex. Last ventral segment broadly 

 shallowly notched, the two lobes thus 

 formed, evenly rounded. 



Color pale greenish gray, sternum, legs, 

 and venter pale yellowish. Face rufous, 

 lighter towards margins ; clypeus and lower 

 part of front, antennae cavities, two diago- 

 nal streaks between the ocelli and front, and 

 a spot extending inward from eyes and 

 including ocellus, deep black. Vertex pale 

 yellowish with two small dots between the 

 median line and the e^'es, and a large black 

 spot at inner angle of eye. Pronotum very 

 finely but distinctly shagreened, with three 

 brown points, one at apex and two on disc. 

 Elytra with dark fuscous clouding in outer 

 claval cell, two anteapical cells and third 

 apical cell. 



State of Vera Cruz, Mexico (Rev. 

 H. Th. Heyde). This peculiar form is 

 an interesting addition to the novella 



group. 



Agallia producta n. sp. 



Resembling anomala. Length of male 

 and female, 3.5 mm. 



Female: Face a twelfth lon^tr then wide. 

 Front broad, sides evenly curved from 

 antennae to clypeus. Vertex of nearly the 

 same form as in anomala and novella. 

 Pronotal width about once and two thirds 

 the length, the length five and a half times 

 that of the vertex. Hind margin' of last 

 ventral segment medially strongly produced 

 to an obtuse point, lateral angles broadly 

 rounded. 



Diflfering in color from anomala as fol- 

 lows : Face pale yellowish, minute dots 

 adjoining the ocelli inwardly, antennae
