the top from the base to the tegule, the apex of tegule narrowly, the point be- 
hind them, the apical half of post-scutellum, the top of mesopleure broadly, a 
line down the base, largely triangularly dilated at the base above, the sides of 
the prothorax broadJy, more broadly on the metanotum than on the pleure, 
the sides of the node of 1st abdominal segment broadly the apex above nar- 
rowly, the apices of the others more broadly all round and the sides of the 
2nd below, red ; the apex of the femora,tibie and the tarsi yellow, tinged with 
rufous. Wings hyaline, the radial cellule smoky, the costa and. stigma black. 
Ocelli in a broad curve, the hinder separated from each other by a distinctly 
greater distance than they are from the eyes. Clypeus, if anything, wider 
than long, strongly but not closely punctured, the apex with a shallow triangu- 
lar incision, the teeth bluntly triangular. Thorax about one half longer than 
wide, the base not quite transverse, its sides broadly roaudly narrowed. 
Apex of post-scutellum obliquely narrowed to the middle. Metanotum with 
a shallow furrow, widened gradually towards the apex. Abdomen as long 
as the thorax, the node one-third of the length of the segment, gradually 
widened towards the apex. 2nd segment longer than it is wide at the apex. 
2d segment longer than it is wide at the apex, the base broadly, gradually 
roundly narrowed. Thoracic punctuation strong, close, running in places 
into reticulations ; there is a smooth, semi-circular space in the besal centre of 
mesopleuw. The basal half of the antennal scape and the greater part of 
the basal 2 joints of the flagellum are rufous. 
1, at first, thought this species might be Z. regulus, Saus., with which it 
agrees closely in general colouration (regulus is very variable, in colouration) 
but Saussure’s species should be readily know from mine by the base of thorax 
being transverse and with the sides angled, while in acapulcensis it is broadly 
rounded and not angled laterally. The general reddish colouration is pretty 
much as in &#. aviculus, Saus. I have this species from Belize, but, that is 
larger and, otherwise, may easily be known by the 2nd abdominal segment 
being clearly punctured.
